Normal Resting Heart Rates by Age

  • Heart Rate by Age
  • How It Is Measured
  • Causes of Low Rates
  • Causes of High Rates
  • What You Can Do

The normal resting heart rate varies by age. In adults, a resting heart rate of 60 to 100 beats per minute (bpm) is generally considered normal. Babies and young children have higher resting heart rates than older kids, teens, and adults.

Resting heart rate is your heart rate while at rest. It serves as an indication of your general fitness. A lower resting heart rate generally indicates a higher degree of fitness. Even so, certain medical conditions can cause an abnormally low or high resting heart rate.

This article explains what the resting heart rate should be for different age groups, how it is measured, and what low or high resting heart rates say about your health.

Normal Resting Heart Rate by Age

From birth to adulthood, the resting heart rate varies. In babies and children, the rate is generally higher, mainly because their hearts are smaller. The rate will gradually decrease until age 10 when the expected range of values will stabilize through adulthood.

The resting heart rate range , measured in bpm, is the expected range of values seen in 95% of people in that age group.

Resting Heart Rate in Older Adults

The normal resting heart rate for people over 10 years of age, including older adults, is between 60 and 100 beats bpm. If the rate is significantly higher or lower, it usually indicates that your functional status is poor.

Functional status, also known as performance status , refers to your ability to perform everyday tasks, to remain mobile, and to live independently at home.

A 2016 study published in the Canadian Medical Association Journal suggests that the resting heart rate alone—independent of sex, medications, and cardiovascular risk factors —influences whether your functional status is good or poor for your age.

To this end, you need to follow the physical activity guidelines issued by the Department of Health and Human Services whether you are a younger or older adult. If you can't manage the recommended 150 minutes of activity each week, be as physically active as your abilities allow.

If you are living with a chronic condition such as heart disease or chronic obstructive pulmonary disease (COPD) , speak with your healthcare provider first to determine what is the most appropriate plan based on your current functional status.

With time and persistence, your functional status—along with your resting heart rate—should improve.

How to Measure Your Heart Rate

Though there are smartwatches and heart rate monitors able to measure your heart rate automatically, all you really need is a watch with a second hand. To get an accurate resting heart rate reading, you need to be at rest.

To measure your heart rate, place a finger over your radial artery or carotid artery . The radial artery is found at the base of the wrist on the side of the thumb. The carotid artery is found on the neck to the side of the windpipe, just under the jaw.

Once you have located the artery, place your index and middle fingers over it and count the number of pulses you feel in one minute. (A quicker method is to count the number of beats over 15 seconds and multiply this by four to determine beats per minute.)

Common Mistakes

There are certain things that can increase your resting heart rate and throw off your reading, including:

  • Having just exercised
  • Walking or doing physical activity
  • Smoking a cigarette
  • Eating a big meal
  • Drinking a lot of caffeine
  • Feeling stressed

If you're doing or feeling any of these things, it is best to wait an hour or two before measuring your heart rate to get the most accurate reading.

What Causes a Low Resting Heart Rate?

A lower-than-normal resting heart rate is called bradycardia . Having a low heart rate is not necessarily a bad thing. Performance athletes like long-distance runners, for example, can have a resting heart rate in the low 40s and still be considered healthy.

However, for most people, a low heart rate may be a sign of a problem, especially when accompanied by:

  • Lightheadedness, dizziness, or fainting
  • Shortness of breath

There are many different causes of bradycardia, including:

  • A congenital heart defect
  • Heart block (caused by problems with the heart's electrical system)
  • Heart damage caused by a heart attack or heart disease
  • Hypercalcemia (abnormally high blood calcium)
  • Hyperkalemia (abnormally high blood potassium)
  • Hyperparathyroidism (overactive parathyroid gland)
  • Hyponatremia (low blood sodium)
  • Hypothermia (low body temperature due to exposure to cold)
  • Hypothyroidism (underactive thyroid)
  • Intracranial pressure (increased pressure under the skull)
  • Lupus (an inflammatory autoimmune disease)
  • Myocarditis (heart muscle inflammation)
  • Obstructive sleep apnea (gaps in breathing during sleep)
  • Sick sinus syndrome (a heart rhythm problem common in adults over 70)
  • Certain medications like sedatives, opioid drugs, beta-blockers , and calcium channel blockers

What Causes a High Resting Heart Rate?

A heart rate higher than 100 bpm is called tachycardia . Aside from recent exercise, many medical conditions are associated with tachycardia, including:

  • Anemia (low red blood cells)
  • Being overweight or having obesity
  • Dehydration
  • Heavy alcohol use or alcohol withdrawal
  • Heart failure (where the heart is less able to pump blood)
  • High levels of anxiety
  • Hypocalcemia (abnormally low blood calcium)
  • Hypokalemia (abnormally low blood potassium)
  • Hypoparathyroidism (underactive parathyroid gland)
  • Hypotension ( low blood pressure )
  • Hypertension (high blood pressure)
  • Hyperthyroidism (overactive thyroid)
  • Smoking tobacco
  • Stimulations like caffeine, nicotine, cocaine, and crystal methamphetamine

Serious Causes of Tachycardia

Some potentially life-threatening conditions can also cause a high resting heart rate, including:

  • Pulmonary embolism (a blood clot in an artery of the lung)
  • Sepsis (a potentially life-threatening complication of an infection)
  • Ventricular tachycardia (rapid heartbeat in the lower chamber of the heart)

Seek immediate medical help if you have rapid heartbeats accompanied by chest pain, difficulty breathing, dizziness, or fainting.

How to Lower Your Resting Heart Rate

You can lower your resting heart rate by improving your physical fitness and making some lifestyle changes. Regular cardio exercise (like running, swimming, or biking) trains the heart to become more efficient over time.

In addition to exercise, other lifestyle modifications may improve your resting heart rate, including:

  • Quitting cigarettes
  • Cutting back on alcohol
  • Reducing your caffeine intake
  • Getting plenty of sleep
  • Losing weight if you have obesity
  • Managing stress with meditation , yoga, or breathing exercises

The aim is to improve what is known as your target heart rate zone . This is your heart rate during moderate-intensity activities (defined as 50% to 85% of your maximum heart rate).

The target heart rate zone and maximum heart rate vary by a person's age.

Your resting heart rate is an indicator of your general fitness, with lower values associated with better health outcomes. For most adults, the normal resting heart rate is 60–100 bpm. It can be even lower in athletes or people who regularly engage in strenuous physical activity.

People can improve their resting heart rate by routinely exercising, quitting smoking, reducing alcohol and caffeine intake, and managing stress.

9 Common pulse points – (Anatomical pulse sites with demonstration)

common-pulse-points-anatomical-pulse-sites

Last updated on December 28th, 2023

The pulse is the palpable throbbing sensation you feel over the peripheral arteries. It occurs as a result of rapid blood flow within the arteries during the contraction of the heart.

There are 9 common pulse points on the body.  You can feel them by lightly palpating the artery against the underlying bone or muscle. 

Monitoring pulse is a crucial part of physical assessment and observing vital signs. The characteristics (eg: abnormally slow, fast, or irregular pulse) of the pulse will give you an indication of the cardiovascular system’s ability to deliver enough blood to the body.

The radial pulse you feel from the radial artery is the most common pulse point for taking pulse in adolescents and adults.

But during a cardiovascular collapse, radial pulse usually will not be palpable. In this case, a more central site like the carotid artery should be used to check for pulse.

This article covers:

  • definition of pulse,
  • characteristics of pulse,
  • normal pulse rate,
  • factors influencing pulse rate,
  • 9 common pulse points on the body, and
  • how to locate pulse sites

Definition of the pulse

The pulse can be defined as a rhythmic wave of pressure formed by the expansion of an artery due to the heart’s contraction of the left ventricle.

Characteristics of the pulse  

When you assess the pulse, you are observing for characteristics of the pulse. The pulse characteristics offers valuable data for determining the integrity of the client’s cardiovascular system. 

Key characteristics of the pulse include:

  • Frequency or pulse rate
  • Rhythm or regularity
  • Strength (amplitude) or intensity

Characteristic of the pulse

1. Frequency or Pulse Rate 

The pulse rate is the pulsation you feel for one minute. The pulse rate should be within the normal range.

See Table 2 for normal pulse rate as per age.

when the pulse rate is below the normal range (less than 60 in adults) is called Bradycardia.

When the pulse rate is above the normal range (more than 100 in adults) is called Tachycardia.

Pulse is documented as pulse beats per minute (bpm). To determine pulse rate, you have to count pulse for 60 seconds. 

For instance, you can write pulse rate as 74/min or 74 bpm.

Note: Always refer your institute’s guideline when documenting.

2. Rhythm or Regularity of Pulse

Rhythm is the time interval between pulse beats. 

You assess the rhythm of the pulse to determine whether it’s regular or irregular. 

Normal pulse beats at regular intervals. 

Irregular pulse indicates irregular contractions of the heart. Then pulse must be assessed bilaterally. Also you refer the client to a senior clinician for further evaluation.

3. Strength (amplitude) or Intensity of Pulse 

The strength of the pulse is the force of blood felt at each heartbeat.

It is determined by the amount of blood pushed out of the heart into the arteries with every heartbeat.

The force will be at normal strength if the client has a normal pulse.

Abnormal strengths of the pulse are:

  • A weak or feeble pulse indicates reduced cardiac output and requires immediate action.
  • A strong, bounding pulse indicates high blood pressure.

The strength of the pulse also should be graded on a scale of 0 to 4 +.

Factors that Affect Pulse Rate

  • Body temperature
  • Emotional status
  • Blood pressure
  • Food intake
  • Medications (stimulants increase the pulse rate and depressants decrease the pulse rate)

9 Common Pulse Points

9 most commonly assessed pulse points on the body by nurses are:

  • Temporal pulse – over the temple
  • Carotid pulse – at the side of the neck
  • Apical pulse – over the 5th intercostal space (ICS) at left mid-clavicular line.
  • Brachial pulse – on the antecubital fossa (crook) of the arm
  • Radial pulse – in the wrist below the thumb
  • Femoral pulse – in the groin
  • Popliteal pulse – behind the knee
  • Posterior tibial pulse – to the side of the ankle
  • Dorsalis pedis pulse – on the front of the foot.

1. Temporal artery pulse

The superficial temporal artery is where you assess temporal pulse with your index and middle fingertips. 

It can be located over the temple just in front of the tragus of the external ear.

Why is temporal pulse measured?

The temporal artery pulse site is assessed during  nursing head-to-toe assessment

Also, this pulse site is easily accessible in children.

2. Carotid artery pulse

The  anatomical location of the carotid pulse is along the medial edge of the sternocleidomastoid muscle in the neck (i.e., mid-line between earlobe and chin below the jawline.)

Use index and middle fingertips to palpate carotid artery.

When you assess carotid pulse, be cautious and feel both sides separately to avoid vagus nerve stimulation. Because it will reduce the heart rate and circulation to the brain.

Why is the carotid pulse measured? 

The carotid artery pulse site is used:

  • to assess peripheral pulse characteristics
  • to assess the presence of pulse when a person collapses and during cardiopulmonary resuscitation (CPR) 
  • when other peripheral pulses are not palpable.

3. Apical pulse 

The apical pulse can be anatomically located over the 5th intercostal space at the left mid-clavicular line. 

Unlike other pulses, the apical pulse is unilateral and auscultated directly over the apex of the heart.

Always count apical pulse for 1 full minute.

Why is the apical pulse measured? 

The apical pulse site is assessed during the head-to-toe assessment, instead of palpating you listen to the apical pulse using the stethoscope.

Apical pulse is the preferred site to measure heart rate in newborns and infants.

4. Brachial artery pulse

The brachial pulse is felt on the anterior aspect of the elbow by gently pressing the artery against the underlying bone with the middle and index fingers (i.e: the groove between the biceps and triceps at the antecubital fossa).

Why is the brachial pulse measured? 

The brachial artery pulse site is used:

  • to measure blood pressure with a stethoscope and sphygmomanometer.
  • to assess the circulation of the lower arm

5. Radial artery pulse

The anatomical position of the radial pulse is immediately above the wrist joint near the base of the thumb.

This is the most commonly measured pulse by nurses to assess peripheral pulse characteristics. 

The radial artery pulse can be felt by gently pressing the radial artery against the underlying bone with the middle and index fingers.

Why is radial pulse measured? 

Radial artery pulse site is assessed:

  • to check blood circulation of the hand
  • to check peripheral pulse characteristics

Click here for a demonstration of how to take radial pulse.

6. Femoral artery pulse

The femoral pulse is anatomically located below the inguinal ligament between the pubic symphysis and anterior superior iliac spine.

Femoral artery pulse are another major pulse you may palpate during shock or cardiac arrest.

Why is femoral pulse measured?  

The femoral artery pulse site is assessed:

  • to check blood circulation of the leg
  • to check pulse during a shock and cardiac arrest

7. Popliteal artery pulse

The popliteal pulse is located behind the knee in popliteal fossa.

This pulse is more difficult to palpate as compared to other pulse sites.

Why is popliteal pulse measured?  

Popliteal artery pulse site is assessed:

  • to auscultate lower limbs blood pressure
  • to check blood circulation of the lower leg

8. Posterior tibial artery pulse

The posterior tibial pulse is anatomically located inner side of the ankles below the medial malleolus.

You can palpate the tibial artery by gently pressing against the underlying bone with the middle and index fingers.

Why is posterior tibial pulse measured? 

The posterior tibial artery pulse site is assessed to check blood circulation of the foot

9. Dorsalis pedis pulse

The anatomical location of the dorsalis pedis pulse is the groove between the first and second toes slightly medial on the top of the foot.

  Why is dorsalis pedis pulse measured? 

Dorsalis pedis artery pulse site is also assessed to check blood circulation of the foot

Pulse is an important general vital sign. The number of pulsing sensations you feel during 1 minute is the pulse rate per minute. And several factors may affect the pulse rate.

The characteristics of the pulse give information about the status of the cardiovascular system.

There are 9 common pulse points on the surface of the body. Namely, temporal pulse, carotid pulse, apical pulse, brachial pulse, radial pulse, femoral pulse, popliteal pulse, posterior tibial pulse, and dorsalis pedis pulse .

Know your numbers: What is your heart rate?

Adult wearing gold checking heart rate on wrist watch

Your heart rate, or pulse, is the number of times your heart beats per minute. Your resting heart rate is when the heart is pumping the lowest amount of blood you need because you're not exercising. If you're sitting or lying down ― and you're calm, relaxed and aren't sick ― your heart rate is typically between 60 and 100 beats per minute.

Other factors that can affect your heart rate include:

  • Air temperature. When temperatures or humidity increases , the heart pumps more blood, so your pulse or heart rate may increase.
  • Body position. Sometimes, when going from sitting to standing, your pulse may go up a little. After a few minutes, it should return to a typical rate.
  • Emotions. If you're stressed, anxious or incredibly happy, your emotions can raise your heart rate.
  • Body size. Body size usually does not increase your heart rate. However, if you're obese, you may have a higher resting heart rate.
  • Medication use. Medications that block adrenaline tend to slow your heart rate. Thyroid medication may raise it.

Why your heart rate matters

Cardiovascular exercise, also called cardio or aerobic exercise, keeps you and your heart healthy. This specific type of exercise gets your heart rate up and your heart beating faster for several minutes. Cardiovascular exercise helps strengthen your heart, allowing it to pump blood more efficiently and improving blood flow to all parts of your body. It also boosts your high-density lipoprotein (or HDL), or "good" cholesterol , and lowers your low-density lipoprotein (or LDL), or "bad" cholesterol. This may result in less buildup of plaque in your arteries.

What's your target heart rate?

Your target heart rate is the minimum heart rate you need to maintain in a given amount of time to reach the energy level necessary to give your heart a good workout. To find your target heart rate to maximize your cardiovascular exercise, the first step is determining your maximum heart rate.

Your maximum heart rate is 220 minus your age. Your target heart rate for moderate to vigorous exercise is about 50%–85% of your maximum heart rate.

Averages by age as a general guide are:

  • 20: 100–170 beats per minute
  • 30: 95–162 beats per minute
  • 35: 93–157 beats per minute
  • 40: 90–153 beats per minute
  • 45: 88–149 beats per minute
  • 50: 85–145 beats per minute
  • 55: 83–140 beats per minute
  • 60: 80–136 beats per minute
  • 65: 78–132 beats per minute
  • 70: 75–128 beats per minute

What you can do

  • Start slow. If you are beginning an exercise program, aim for the lower end of your target heart rate zone and then gradually build up intensity.
  • Try interval training. Interval training , which includes short bursts ― 15–60 seconds ― of higher-intensity exercise, alternated with longer, less strenuous exercise, effectively increases cardiovascular fitness. Talk with your healthcare team before trying interval training, but it is typically safe for those with existing heart disease and Type 2 diabetes.
  • Take the "talk test." If you can carry on a conversation in brief sentences while exercising, you're probably in the moderate intensity range. You'll be breathing faster, developing a light sweat and feeling some muscle strain. If you're working at a vigorous intensity, you won't be able to say more than a few words without catching your breath. If you can sing while working out, you're probably in the low-intensity range, so step it up.

Know your numbers

Many wearable activity trackers can monitor your heart rate when you exercise and periodically throughout the day. If you don't have an activity tracker, you can use the radial artery in your wrist or the carotid artery in your neck. If you have heart disease or long-standing diabetes, it's best to use the artery on your wrist.

To find your heart rate manually:

  • Locate the artery you will use to find your heart rate.
  • Using the tips of your first two fingers, press lightly over the artery.
  • Count your heartbeats for 30 seconds and multiply by two to find your total beats per minute.

If your heart rate is too high, take it easier. If it's too low, add some intensity and push yourself to get your heart rate closer to your target.

Abnormal heart rate

If you experience irregular heartbeats, including a racing heartbeat, slow heartbeat or a feeling of fluttering in your chest, you may be experiencing a heart arrhythmia . Heart rhythm or heartbeat problems can occur when the electrical impulses that coordinate your heartbeats don't work properly, causing your heart to beat too fast, slow or irregularly. Talk with your healthcare team if you have heart rhythm concerns.

Readers' Questions

What is a 3 pulse in medicine?
In medicine, a "3 pulse" typically refers to the palpation of the radial artery in the wrist, which corresponds to three beats felt with each cardiac cycle. It indicates a normal pulse rate.
Are thready and 1 pulses the same thing?
No, "thready" and "1 pulses" are not the same thing. "Thready" typically refers to a weak or feeble pulse, indicating a low blood pressure or a weak circulatory system. On the other hand, "1 pulses" may refer to counting the pulse on the wrist, where each pulsation is labeled as "1" during the counting process. It is a method used in determining the heart rate or pulse rate.
What does plus2 pedal pulse mean?
A plus 2 pedal pulse refers to the strength, or amplitude, of a pulse felt on the foot. In medical terms, plus 2 pedal pulse indicates a strong and easily palpable pulse on the foot, which suggests good blood circulation to the foot and lower extremities. This assessment is usually done by a healthcare professional to evaluate the peripheral vascular status of a patient.
What is a good pluse 04?
Pulse 04 is a Bluetooth speaker model manufactured by JBL. It is known for its excellent audio quality, robust build, and unique LED light show feature. The speaker offers a 360-degree sound experience and comes with a built-in rechargeable battery for portable use. Additionally, it is water-resistant and can be connected to multiple devices simultaneously. Overall, JBL Pulse 04 is a popular choice for those looking for a reliable and feature-packed Bluetooth speaker.
How to describe pedal pulse?
Pedal pulse refers to the pulse felt in the foot, specifically the dorsalis pedis artery and posterior tibial artery. It is commonly assessed in medical examinations to determine the blood flow and overall health of the lower extremities. When describing pedal pulse, you can consider the following characteristics: Location: Identify the location where the pulse is felt, usually on the top of the foot for the dorsalis pedis artery or behind the inner ankle for the posterior tibial artery. Strength: Note the strength or intensity of the pulse. You can use terms like strong, weak, thready, bounding, or absent to describe it. Rate: Determine the rate or frequency of the pulse, typically measured in beats per minute. It may be described as fast, slow, regular, or irregular. Rhythm: Observe the rhythm of the pulse. It should ideally be regular and consistent. Mention if there is any abnormality, such as irregularity or intermittent pulsations. Quality: Assess the quality or character of the pulse. You can use descriptors like full, weak, pulsating, steady, or easily palpable. Symmetry: Compare the pulses between both feet. Note if they have similar characteristics or if there is any significant difference in strength, rhythm, or quality. For example, you could describe pedal pulse as follows: "The dorsalis pedis pulse was readily palpable on the top of the right foot, exhibiting a strong and regular pulsation with a rate of 80 beats per minute. In comparison, the posterior tibial pulse on the left foot was weaker and slightly irregular, with a rate of 70 beats per minute. No significant asymmetry was noted."
What is fast and thready pulse?
A fast and thready pulse refers to a heartbeat that is rapid and weak. It is characterized by a rapid heart rate (above the normal range) but a weak and faint pulse when felt at the radial artery (wrist) or carotid artery (neck). This can occur due to various reasons, including dehydration, low blood pressure, bleeding, shock, heart failure, or certain medical conditions. It is important to seek medical attention if experiencing a fast and thready pulse, as it may indicate a serious underlying health issue.
Which grade denotes a normal pulse strength?
A normal pulse strength can vary among individuals and may also be influenced by factors such as age, fitness level, and underlying health conditions. However, in general, a grade 2 pulse strength is considered normal.
Is 2 pluse strength bad?
No, 2 plus strength is not bad. In fact, it indicates that a person has above average strength.
How to read pulses 2 3?
To read pulses of 2 and 3, you would need to use a pulse sensor or a similar device that can detect and measure pulses. Here are the steps to follow: Obtain a pulse sensor: You can purchase a pulse sensor from an electronics store or online marketplace. Connect the pulse sensor: Follow the instructions provided with the pulse sensor to connect it to a microcontroller or development board. Typically, the sensor will have three pins - power, ground, and signal. Connect the power and ground pins to a suitable power source and connect the signal pin to a digital input pin on the microcontroller. Read the pulses using code: Write a program in a suitable programming language (such as Arduino or Python) to read the pulses from the sensor. Use the digital input pin connected to the sensor to read the state of the pulses. For example, in Arduino, use the `digitalRead()` function to read the digital signal from the pulse sensor. Measure the pulses: Now that you can read the digital signal from the pulse sensor, you can measure the pulses. Each pulse will correspond to a change in the state of the signal. You can count the number of pulses over a certain period of time or measure the duration between successive pulses to calculate the pulse rate. Note: It's important to understand that the number 2 and 3 mentioned in your question might refer to something specific in your context. If you can provide more information or clarify your question, I can give a more specific answer.
How to grade pulses sample chart?
Grading pulses involves evaluating their appearance, texture, color, size, and overall quality. Here's a general guideline on how to grade pulses using a sample chart: Gather your samples: Collect a representative sample of pulses that you want to grade. Ensure that you have enough variability in terms of quality and characteristics. Create a grading chart: Prepare a chart that includes the parameters you want to assess. Common factors to consider are appearance, texture, color, size, and defects. Divide each parameter into different grades or categories, ranging from excellent to poor. Evaluate appearance: Look at the pulses and note their overall appearance. Assess factors such as cleanliness, shape, moisture content, uniformity, and any visible defects. Assign a grade to each sample based on your chart. Assess texture: Feel the pulses between your fingers to assess their texture. Determine whether they are firm, soft, chewy, or have any undesirable textures. Use your grading chart to assign a suitable grade. Examine color: Evaluate the color of the pulses, noting any variations or inconsistencies. Ensure that the color is typical for the respective variety. Grade the samples according to the color parameter on your chart. Measure size: Measure the size of the pulses using appropriate tools, such as a sieve or caliper. Compare the size with the desired range for that particular pulse type. Assign grades based on size conformity. Identify defects: Look for any defects in the pulses, such as damaged, discolored, insect-damaged, or shriveled ones. Note the number and severity of defects and determine the appropriate grade based on your chart. Summarize the grades: Once you have evaluated all the parameters for each sample, summarize the grades for each category. Calculate an overall grade for each sample, considering all the parameters you assessed. Interpret the grades: Based on the grading chart, interpret the grades for each sample. Identify patterns, trends, and areas of improvement. This information can guide decisions related to the quality, market value, and potential uses of the pulses. Note: The grading process may vary slightly depending on local standards, regulations, or specific requirements for different pulse varieties. It's important to refer to any relevant guidelines or specifications set by grading authorities or industry organizations in your region.
How to document dorsalis pulses on exam?
To document dorsalis pulses on an exam, you can follow these steps: Position the patient: Ensure that the patient is comfortably lying down or sitting with their legs uncrossed. Locate the dorsalis pedal pulse: The dorsalis pulse is located on the top of the foot, between the first and second metatarsal bones. Use your fingers to gently feel for the pulse. Palpate the pulse: Place your index and middle fingers over the area where the dorsalis pulse is located. Apply gentle pressure and move your fingers in a back-and-forth motion to feel the pulse. Assess the pulse quality: Pay attention to the strength and regularity of the pulse. Note whether it is bounding, weak, or absent. You can use a scale (such as 0-4+) to document the strength of the pulse. Document the findings: Record your findings in the patient's medical chart or exam notes. Include the following information: - Date and time of the examination - The location of the pulse (dorsalis pedal) - Pulse strength (e.g., 2+) - Any abnormalities or notable findings (e.g., bounding pulse) - Patient's symptoms or complaints related to the pulse, if applicable For example, you might write: "Dorsalis pulses palpated and found to be 2+ bilaterally. No abnormalities noted. Patient denies any pain or numbness in the feet." Remember to use clear and concise language when documenting to ensure accurate communication of the patient's condition.
How to document peripheral pulse strength?
To document peripheral pulse strength, follow these steps: Wash your hands thoroughly before assessing the pulse. Find a comfortable and well-lit area to perform the assessment. Explain the procedure to the patient and ensure their comfort. Locate the peripheral pulse, commonly assessed in the radial artery (wrist). Gently palpate the pulse using your index and middle fingers. Pay attention to the strength, regularity, and volume of the pulse. Assign a numeric value to describe the pulse strength using the following scale: - 0 = Absent pulse - 1+ = Barely palpable or very weak pulse - 2+ = Easily palpable and slightly weak pulse - 3+ = Normal or optimal pulse strength - 4+ = Strong and bounding pulse Note any variations or abnormalities, such as irregular rhythm or weak thready pulse. Record the pulse strength along with the date, time, and your initials on the patient's medical chart or assessment form. Communicate the findings to the appropriate healthcare professionals involved in the patient's care. Remember to practice and become familiar with assessing peripheral pulses to ensure accurate and consistent documentation.
How to chart positive pedal pulses?
To chart positive pedal pulses, follow these steps: Position the patient: Ask the patient to lie down on a comfortable examination table or bed, positioning them with their legs straight and relaxed. Prepare the patient: Help the patient to relax by ensuring they are comfortable and at ease. This can be achieved by providing a warm environment, offering a supportive pillow, and maintaining good communication throughout the procedure. Locate the pedal pulse: Find the pedal pulse by palpating the dorsalis pedis artery or the posterior tibial artery. The dorsalis pedis artery is located on the top of the foot, between the first and second metatarsal bones and can be felt slightly lateral to the extensor hallucis longus tendon. The posterior tibial artery is found behind the medial ankle bone (medial malleolus). Use proper technique: Apply firm but gentle pressure with your index and middle fingers on the palpated area over the artery. Feel for rhythmic pulsations. Assess the pulse: Pay attention to the strength, rate, and regularity of the pedal pulse. Note the intensity of the pulsations as either strong, weak, or absent. Also, count the number of beats per minute to determine the pulse rate. Finally, assess whether the pulse is regular or irregular. Document the findings: Use an appropriate charting system to record your assessment. A common method is to use a standardized flowchart or an electronic medical record system. Make sure to document the location of the pulse, the strength, and any other relevant observations, such as rhythm or absence. Repeat the process if needed: If the initial assessment was challenging or inconclusive, repeat the procedure on both feet to ensure accuracy and consistency. Remember, if you encounter difficulty or have concerns about the patient's pedal pulse, it is essential to seek assistance from a healthcare professional, such as a nurse or physician, for further examination and evaluation.
Who established 0 1 2 3 for pulses?
The concept of using 0 and 1 as binary digits (bits) was established by Gottfried Wilhelm Leibniz, a German mathematician and philosopher, in the late 17th century. This binary system was further developed and used in electronic circuitry by Claude Shannon and his colleagues, leading to the use of binary digits for pulses in modern computing.
What are the strength of pulses rated as ( 4)?
A rating of (4) for the strength of pulses can indicate the following strengths: Strong: A rating of (4) implies that the pulses are strong, exhibiting a forceful and vigorous sensation when felt. The pulsations can be easily felt and have a powerful impact. Full: It suggests that the pulses are complete and fully perceived. The rhythm and intensity of the pulses are distinct and easily discernible. Robust: The strength of the pulses is substantial and robust. They may be described as powerful and able to be easily detected. Forceful: The pulsations are forceful, indicating a significant surge of blood flow. It may feel as though the pulses are pushing against the surface of the body. Overall, a rating of ( 4) for the strength of pulses suggests that they are strong, forceful, and easily palpable.
How to describe pulses?
Pulses are rhythmic and regular movements or vibrations that travel through a medium (such as a body part, a substance, or a wave). They can be described in the following ways: Frequency: This refers to the number of pulses occurring in a given time frame. It is measured in hertz (Hz), which represents the number of pulses per second. Amplitude: This describes the size or magnitude of the pulses. It indicates the maximum displacement or disturbance caused by the pulse. Amplitude can be high or low, signifying strong or weak pulses respectively. Waveform: Pulses can have different shapes and patterns as they propagate. They can be described as being sinusoidal (smooth and symmetrical), square (sudden and rapidly changing), or triangular (gradual rise and fall). Speed: The rate at which pulses travel through a medium is known as speed. It can be fast or slow, depending on the properties of the medium and the nature of the pulse. Duration: This refers to the length of time that a pulse lasts before it dissipates or disappears. Pulses can be brief, lasting for only a fraction of a second, or they can endure for more extended periods. Energy: Pulses can carry energy from one point to another. The energy of a pulse is directly related to its amplitude. Higher amplitude pulses contain more energy. Direction: Pulses can propagate in different directions. They can travel in a straight line, bounce off boundaries, or be reflected or refracted when encountering different media. Interference: When two or more pulses overlap or interact with each other, they can either combine constructively (increasing amplitude) or destructively (decreasing or cancelling out amplitude). Interference patterns may form depending on the properties of the pulses. By using these descriptions, one can effectively communicate the characteristics and properties of pulses.
Which grade pulse (quality) is considered normal?
A normal resting heart rate for adults is typically between 60-100 beats per minute. However, heart rate can vary based on various factors such as age, fitness level, and overall health. It is always best to consult with a healthcare professional for a more accurate evaluation of your specific heart rate.
How to desbribe a full pulse?
A full pulse can be described as strong and regular, with a palpable beating sensation that can be felt throughout the body. It is characterized by a firm, consistent rhythm and can be easily detected by placing fingers on a major artery, such as the radial artery in the wrist or the carotid artery in the neck. A full pulse signifies a healthy cardiovascular system and a normal blood flow rate.
How to grade normal pulse feet?
To grade a normal pulse in the feet, you can follow these steps: Find a comfortable and quiet environment to assess the pulse in the feet. Have the person lie down on their back or sit in a chair with their legs uncrossed and feet exposed. Sit or kneel beside the person and elevate one of their feet so that it is at a comfortable height for you to access. Locate the pulse point in the foot - it is typically found on the inner side of the ankle, just below the ankle bone, and slightly towards the arch of the foot. Place your index and middle fingers gently over the pulse point. Apply slight pressure, but not too much as it could obstruct the pulse. Feel for the pulsations. The normal pulse in the feet should feel regular, steady, and have a moderate strength. Each beat should have a distinct "thump" that you can feel between your fingers. Count the pulses for 15 seconds or 30 seconds and multiply the count by 4 or 2, respectively, to get the pulse rate per minute. Repeat the process on the other foot to ensure consistency. Compare the pulse rate to the normal range, which is generally between 60 to 100 beats per minute (bpm) for adults. If the pulse rate falls within the normal range and feels regular and steady, you can consider the pulse in the feet as graded as normal. Note: It's important to mention that grading a pulse should ideally be done by a trained healthcare professional. If you have any concerns or suspect any abnormalities, it is best to consult a healthcare provider.
How to document radial pulse?
To document the radial pulse, follow these steps: Patient Position: Ask the patient to sit or lie down comfortably and relax their arm, palm facing upwards. Locate the Radial Artery: Find the radial artery on the wrist by placing your index and middle fingers on the wrist's inner side, just below the base of the thumb. Assess the Pulse: Lightly press your fingers against the radial artery, feeling for the pulsations. Note the rate, rhythm, and strength of the pulse. - Rate: Count the number of beats felt in one minute. If the pulse is regular, count for 30 seconds and multiply by 2 for a quicker assessment. - Rhythm: Determine if the pulse is regular (consistent spacing between beats) or irregular (varying spacing between beats). Note any irregularities. - Strength: Assess the strength of the pulse as weak, normal, or strong. Compare it to your own pulse or use a pulse strength grading system if available. Documentation: Record the obtained information in the appropriate format or system, such as a patient chart or electronic medical record. - Write down the time and date of the assessment. - Include the rate, rhythm, and strength of the pulse using appropriate descriptors. - Note any subjective observations, such as a bounding or weak pulse, or presence of irregularities. Interpretation: Compare the recorded data with the individual's normal baseline or expected ranges for their age and health status. Monitor and Follow-up: Document any changes in the pulse during subsequent assessments. Note variations from previous recordings or any concerning patterns. Note: Apart from documenting pulse, it is crucial to assess other vital signs, such as blood pressure, respiratory rate, and oxygen saturation, to gain a comprehensive evaluation of a patient's overall condition.
Which grade is given to the normal strength of a pulse?
The normal strength of a pulse is typically graded as 2+, which indicates a normal and easily palpable pulse.
How to chart arterial pulses?
Charting arterial pulses involves documenting the rate, rhythm, and quality of the pulse. Here's a step-by-step guide on how to chart arterial pulses: Assess the location: Identify the location of the pulse you want to chart. Commonly charted arterial pulses include the radial artery (located at the wrist), carotid artery (located in the neck), and pedal pulses (located in the foot). Wash hands: Proper hand hygiene is essential before any patient care. Wash your hands thoroughly with soap and water or use hand sanitizer. Prepare the patient: Explain the procedure to the patient and ensure they are in a comfortable position. Make sure the limb is exposed and easily accessible. Find the pulse: Use your fingertips to locate the pulse at the chosen location. Apply gentle pressure until you feel the pulsation. Take note of any difficulty in finding the pulse. Assess the rate: Count the number of beats you feel within a 60-second time frame. Use a watch with a second hand or a digital timer to ensure accuracy. Determine the rhythm: Assess the regularity of the pulse. If the beats are evenly spaced, it is considered regular. If there are irregular intervals between beats, it is considered irregular. Evaluate the quality: Pay attention to the strength and quality of the pulse. Using your fingertips, assess if the pulse is weak, normal, or bounding (strong). Descriptive terms like thready, strong, or full can be used to indicate the quality of the pulse. Document the findings: Use a charting system or electronic medical record to record the pulse assessment. Include the location (e.g., Radial Pulse), rate (e.g., 80 beats per minute), rhythm (e.g., regular), and quality (e.g., normal/strong). Report any abnormalities: If you notice any abnormalities or significant changes in the arterial pulse, report it to the appropriate healthcare professional for further assessment and intervention. Remember to follow the specific charting protocols of your healthcare facility and document all findings accurately and objectively.
How do you describe a patients pulse that is palpable but not bounding?
A patient's pulse that is palpable but not bounding can be described as being present and detectable, but not excessively strong or forceful. It can be felt and measured, but lacks the heightened intensity typically associated with a bounding pulse.
The strength of pulses is rated on a scale of 0-4, with 4 being the strongest.
How to describe pulse quality?
Pulse quality refers to the characteristics of a person's pulse that can be felt and assessed by a healthcare professional. It can provide important information about the person's overall health and cardiovascular system. Here are some ways to describe pulse quality: Rate: This refers to the number of pulsations felt per minute. The pulse rate can be described as fast (tachycardia), normal (around 60-100 beats per minute), or slow (bradycardia). Rhythm: Rhythm describes the regularity or irregularity of the pulse. A regular pulse has an equal time interval between each beat, while an irregular pulse may have inconsistent intervals. Common irregularities include skipped beats or extra beats. Strength or amplitude: This refers to the force or intensity of the pulse. A pulse can be described as strong, weak, or normal. It can be assessed on a scale from absent (0) to bounding (4+). Equality: This describes whether the pulse is the same on both sides of the body. For example, a pulsation that is weaker on one side compared to the other may indicate an underlying condition. Contour: Contour refers to the shape or waveform of the pulse. It can be described as smooth or erratic. Certain conditions or diseases may cause an abnormal pulse contour. Symmetry: Symmetry relates to the evenness of the pulse when comparing different pulse points of the body. Assessing the pulse at multiple locations, such as both wrists or both carotid arteries, helps determine if the pulse is symmetrical. Volume: Volume refers to the amount of blood being pumped with each heartbeat. It can be described as full or diminished. Assessing volume can aid in identifying conditions such as dehydration or fluid overload. When describing pulse quality, it is essential to be as precise and accurate as possible to ensure proper diagnosis and treatment. It is always best to leave the final interpretation and diagnosis to a trained healthcare professional.
What is a full, increased pulse is being graded as?
When a pulse is described as "full" and "increased," it typically indicates that the pulse is strong and forceful, with an elevated rate. This can occur in various situations, such as during exercise, emotional stress, fever, or certain medical conditions. A full, increased pulse can be an indication of a heightened cardiovascular response or increased blood flow in the body. However, it is important to consult a healthcare professional for an accurate assessment and appropriate management of any abnormal pulse.
If pulses are rated as a strength of 4, it implies that the pulses are strong and forceful.
How to assess pedal pulses?
Assessing pedal pulses involves examining the strength and quality of the pulses in the feet. Here is a step-by-step guide on how to assess pedal pulses: Position: Have the person being assessed lie down or lay on their back in a comfortable position. Make sure their feet are accessible and exposed. Warm up: Before assessing the pulses, it's good to warm up the person's feet by gently rubbing them or massaging them for a few minutes. This helps to improve blood flow and make the pulses easier to feel. Locate the pulse: Begin by finding the location of the pedal pulse. There are two main pedal pulses to assess, the dorsalis pedis pulse on the top of the foot, and the posterior tibial pulse on the inside of the ankle along the Achilles tendon. Use the pads of your fingers to feel for the pulse. Assess strength: Once you've located the pulse, use your index and middle fingers to gently press down on the pulse. Assess the strength or force of the pulse. It can range from absent or weak to normal or bounding. A weak pulse may feel faint and barely detectable, while a strong pulse will have noticeable force. Assess rhythm: While feeling for the pulse, also pay attention to the rhythm of the pulses. The rhythm should be regular and consistent. Any irregularities should be noted. Assess bilateral: Repeat the same process on the opposite foot to compare the strength and quality of the pedal pulses bilaterally. This helps to identify any asymmetries or abnormalities. Document the findings: Once you have assessed both pedal pulses, document your findings in the appropriate medical records or assessment form. Include the strength, rhythm, and any notable findings or abnormalities. Remember, if you are not a healthcare professional or have limited experience, it is best to seek professional medical attention for a thorough assessment of pedal pulses.

Check the quality: Determine whether pulses are arterial (tapping) or venous (throbbing). Grade the pulse: Generally, a normal pulse is graded from 0 to Grade 0 indicates no palpable pulse, Grade 1 indicates very weak, Grade 2 indicates weak, Grade 3 indicates normal, and Grade 4 indicates strong.
How to detect pulse grading?
Pulse grading is used to assess a person's pulse rate and is based on the size and strength of the pulse at the radial artery. To detect pulse grading, a medical professional or clinician can use a stethoscope to listen for the pulse beat at the wrist or neck. They can then count the number of beats in a 15-second period and multiply that number by four to get the pulse rate. During the assessment, the examiner can then grade the pulse rate by noting the strength and size of the pulse at each beat. The grading system usually ranges from 0 (absent pulse) to 4+ (very strong pulse).
High Nutrition Value: Pulses are a powerhouse of proteins, vitamins, minerals, and dietary fiber. They are a rich source of proteins and minerals. Low Glycemic Index: Pulses are low in glycemic index which helps to reduce sugar level in the body and helps in controlling diabetes. Good Source of Fiber: Pulses are a good source of dietary fiber which helps to improve digestion and reduces the risk of constipation. High in Antioxidants: Pulses are rich in antioxidants which helps to protect the body cells from the damage caused by free radicals.

How to grad epulses 2 1?
To write "grad epulses 2 1" correctly, you may mean "grade impulses 2 1." Here is a possible interpretation of this request: To grade impulses on a scale of 2 to 1, you can follow these steps: Clearly define the criteria for grading: Determine what factors or qualities you want to evaluate in the impulses. For example, if you are grading creative impulses, you might consider originality, relevance, or execution. Assign a numerical value: Decide on a numeric scale that ranges from 2 to For instance, you can establish 2 as the highest grade and 1 as the lowest. Evaluate each impulse: Analyze each impulse based on the previously defined criteria. Assess how well the impulses meet the standards you set. Assign grades: Assign a numeric value of either 2 or 1 to each impulse, depending on its performance in meeting the criteria. 2 reflects a higher grade, indicating that the impulse meets the criteria exceptionally well, while 1 means the impulse falls short or does not meet the requirements as expected. Provide feedback: If possible, give constructive feedback to explain the rationale behind the assigned grades. This can help the individuals receiving the grades understand how they performed and how they can improve. Remember that this interpretation assumes you want to grade impulses on a scale from 2 to If your question had a different meaning, please provide more context or clarify the intention, and I'll be happy to assist you further.

What's a normal resting heart rate.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute.

Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

To measure your heart rate, simply check your pulse. Place your index and third fingers on your neck to the side of your windpipe. To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist.

When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.

Keep in mind that many factors can influence heart rate, including:

  • Fitness and activity levels
  • Being a smoker
  • Having cardiovascular disease, high cholesterol or diabetes
  • Air temperature
  • Body position (standing up or lying down, for example)
  • Medications

Although there's a wide range of normal, an unusually high or low heart rate may indicate an underlying problem. Consult your doctor if your resting heart rate is consistently above 100 beats a minute (tachycardia) or if you're not a trained athlete and your resting heart rate is below 60 beats a minute (bradycardia) — especially if you have other signs or symptoms, such as fainting, dizziness or shortness of breath.

Word History

Middle English pous, pouce, pulse, borrowed from Anglo-French & Latin; Anglo-French pous, polz, puls, borrowed from Latin pulsus "action of beating or striking, beat, stroke, beat of the heart" ("pulse" in phrase pulsus venārum/artēriārum, literally, "beating of the veins/arteries"), noun of action from pellere "to beat against, push, strike, rouse, expel, repulse," of uncertain origin

Note: The etymology of pellere is problematic, because it lacks an obvious formal and semantic counterpart in other Indo-European languages. A traditional explanation derives it from a base *pel-d-, with the *-d- a present-tense formative marking an action reaching a definite termination (thus Ernout and Meillet in Dictionnaire étymologique de la langue latine, 8. édition, 1985; cf. tender entry 3 ). A hypothetically related form would be Greek pállō, pállein "to poise (a missile before it is thrown), brandish, swing, shake" (Epic aorist pêlai, 3rd singular passive pálto ), though semantically the comparison is weak. A base *pel-d- would correctly produce the past participle pulsus (from *poltos < *pl̥d-t-os ); however the frequentative verb pultāre "to strike repeatedly," attested in Plautus alongside pulsāre, suggests that the original past participle may have been *pultus. According to an alternative hypothesis, pellere is descended from an Indo-European base *pelh 2 - "approach, draw near," seen in Greek pílnamai "I draw near to, make contact with," 3rd singular aorist plêto, verbal adjective in the negated form áplētos, áplātos "unapproachable, monstrous." (The assumed semantic shift is from "approach, touch" to "push, strike.") Both Latin and Greek verbs would continue a present with nasal infix *pl̥-ne-h 2 -/pl̥n-h 2 -. These presumably are seen also in Umbrian ampentu, apentu, ampetu, 3rd singular imperative (allegedly "touches, brings near," with the prefix an- "up, upon," but the meaning of this verb, describing the first action of an animal sacrifice in the Iguvine Tables, is quite uncertain); Old Irish ˑella in adˑella "(s/he) visits, approaches," doˑella "(s/he) turns aside, goes astray" (< *φal-na- ?; e-vocalism is secondary) and eblaid "(s/he) will drive/impel," suppletive future to aigid "(s/he) drives" (< *pi-plā- ); Middle Welsh el, 3rd person singular present subjunctive of mynet "to go" (< *pel-ase/o- ). Note that alongside pellere there is a group of first-conjugation verbs with the same base pell- that occur only with prefixes: appellāre "to speak to, address, name," compellāre "to address, appeal to, rebuke," interpellāre "to interrupt" (see appeal entry 2 , compellation , interpellate ). According to P. Schrijver ( The Reflexes of the Proto-Indo-European Laryngeals in Latin, Rodopi, 1991, pp. 408-12), these are a relic of an original nasal present *pel-n-a-C (< *pl̥-ne-h 2 - with full-grade vocalism) given a thematic suffix *-i̯e/o- in derivatives. These verbs have the common underlying sense "to address (positively or negatively)," which fits fairly well with the hypothetical meaning "approach" of the base *pelh 2 -. For English borrowings of prefixed forms of pellere see compel , dispel , expel , impel , propel , repel .

Middle English puls , probably from Anglo-French puuiz gruel, from Latin pult-, puls , probably from Greek poltos

O Captain! My Captain! Summary & Analysis by Walt Whitman

pulse trip meaning

“O Captain! My Captain!” is an elegy written by Walt Whitman in 1865 to commemorate the death of President Abraham Lincoln. It was first published in Sequel to Drum-Taps (1865), a collection of Whitman’s poems inspired by the events of the American Civil War. The poem is perhaps Whitman’s most famous—which is ironic, since it is far more conventional in meter, form, and subject than much of Whitman’s other work. Although some critics have suggested that Whitman regretted ever writing “O Captain! My Captain!” it undeniably captured the mood of a nation in mourning and has remained one of Whitman’s best-loved and most-quoted poems.

The Full Text of “O Captain! My Captain!”

1 O Captain! my Captain! our fearful trip is done,

2 The ship has weather’d every rack, the prize we sought is won,

3 The port is near, the bells I hear, the people all exulting,

4 While follow eyes the steady keel, the vessel grim and daring;

5                          But O heart! heart! heart!

6                             O the bleeding drops of red,

7                                Where on the deck my Captain lies,

8                                   Fallen cold and dead.

9 O Captain! my Captain! rise up and hear the bells;

10 Rise up—for you the flag is flung—for you the bugle trills,

11 For you bouquets and ribbon’d wreaths—for you the shores a-crowding,

12 For you they call, the swaying mass, their eager faces turning;

13                          Here Captain! dear father!

14                             This arm beneath your head!

15                                It is some dream that on the deck,

Pulse Oximeter Chart – Safe, Normal & Low Blood Oxygen Levels

When using a pulse oximeter at home, it is important that you understand what the readings mean.

What exactly is the impact of safe, normal & low blood oxygen levels , and how should you respond?

Essentially, blood oxygen levels are important as they provide information on how blood cells are transporting oxygen around the body.

Each cell can carry up to four oxygen molecules , and you clearly need a good supply to keep vital organs such as the heart and brain working at optimum levels.

In short, vital systems need a normal percentage of oxygen inside your blood at all times.

This is known as oxygen saturation, and you use a pulse oximeter to measure this.

Blood Oxygen Saturation Levels

OXYGEN SATURATION LEVELS CHART 1

Pulse Oximeter Readings

Oxygen levels are measured in relation to the percentage of oxygen saturated in your blood. In medical terms, this is your SpO2 level.

Normal Blood Oxygen Levels

The normal blood oxygen saturation rate is between 95% and 100% .

‘Concerning’ Blood Oxygen Levels

If oxygen concentrations fall between 91% and 95%, it is a cause for concern . This signifies an underlying medical problem and it is advised that if you have a reading in this range, that you contact your healthcare provider.

Low Blood Oxygen Levels

Low blood oxygen rate is medically defined as percentages that fall below 90% oxygen saturation. In short, readings at this level indicate a medical emergency. You should call 911 immediately if blood oxygen saturation falls this low

Below 85% Oxygen Saturation Levels

If a patient’s oxygen saturation level falls to 85% or below , the brain is being adversely affected due to lack of oxygen. Symptoms include vision changes or loss of vision and total blackout.

If blood oxygen saturation levels fall to around 67%, Cyanosis will set it.

The lack of oxygen being transported by your blood cells, causes a blue tinge to develop on your skin. Your mouth, lips, and beneath your fingernail matrix will be affected first, followed by the spread occurring over the rest of your body.

Final Words

Understanding blood oxygen saturation levels is very important when using a pulse oximeter at home. If you take a reading lower than 95% you now know that action does need to be taken.

3 thoughts on “Pulse Oximeter Chart – Safe, Normal & Low Blood Oxygen Levels”

Your color chart is seriously in need of help. The light text is almost impossible to read even the two columns on the right are hard to read. Seriously someone needs to do a little quality check on this page.

You seem to have a notation error for the O2 Oximeter Chart and the written description below the chart. ” >= 90% Low Blood Oxygen Levels”. The notation you are using is incorrect; “>= ” means Greater than or equal to any value that is listed to its left, which in this case is assumed to be the value for Oxygen saturation. You need to reverse the symbol to : <= , which would indicate an O2 value LESS THAN or EQUAL TO 90% represents "Low Blood Oxygen Levels", which is obviously your intent.

For the orange box above, with 91%, I think it would be less than 91, not greater than. I believe the > sign above should be <

National Security Adviser Makes Covert Trip to Kyiv

Jake Sullivan met with President Volodymyr Zelensky of Ukraine and his senior officials as additional U.S. aid continued to languish in the House.

  • Share full article

Jake Sullivan, in a black suit and a red tie, speaks into a microphone while seated in front of American and Ukrainian flags. Next to him is Andriy Yermak, the head of the presidential office of Ukraine, who is wearing green military-style clothes.

By Zolan Kanno-Youngs

Reporting from Phoenix

President Biden’s top national security official made a secret trip to Kyiv on Wednesday, as Ukrainian soldiers holding off Russian troops are running out of munitions and U.S. aid remains stalled in congressional gridlock.

Jake Sullivan, the national security adviser, met with President Volodymyr Zelensky of Ukraine and his senior officials “to reaffirm the United States’ unwavering commitment to Ukraine in its self-defense against Russia’s brutal invasion,” said a national security spokeswoman, Adrienne Watson. “He stressed the urgent need for the U.S. House of Representatives to pass the national security supplemental to meet Ukraine’s critical battlefield needs.”

The covert trip showed the rising sense of urgency in the White House to pressure Congress to pass billions of dollars of aid for Ukraine, a financial package that the Biden administration says the country needs to defend itself against Russia.

The White House has tried, so far unsuccessfully, to push House Republicans to support a $60 billion emergency spending plan for weapons for Ukraine and to bolster armament production in the United States.

With that funding held back and future U.S. aid in limbo, the administration last week sent Ukraine a $300 million package that included air defense interceptors, artillery rounds, armor systems and an older version of the Army’s longer-range missile systems known as ATACMS. But that package is most likely going to hold off Russia for only a matter of weeks, U.S. officials have said.

“Ukrainian troops have fought bravely, are fighting bravely throughout this war,” Mr. Sullivan said when the package was announced, “but they are now forced to ration their ammunition under pressure on multiple fronts.”

Mr. Sullivan’s visit came one day after Defense Secretary Lloyd J. Austin III met with other backers of Ukraine in Germany to strategize on how to maintain military support for Kyiv.

“Ukraine’s battle remains one of the great causes of our time,” Mr. Austin said.

Our Coverage of the War in Ukraine

News and Analysis

Ahead of the U.S. elections, Russia is intensifying efforts to elevate candidates  who oppose aid for Ukraine and support isolationism, disinformation experts say.

A large-scale Russian missile and drone attack damaged power plants  and caused blackouts for more than a million Ukrainians in what Ukrainian officials said was one of the war’s largest assaults on energy infrastructure.

Russian missiles streaked into Kyiv  in the biggest assault on the Ukrainian capital in weeks, injuring several people and damaging several buildings.

Symbolism or Strategy?: Ukrainians say that defending places with little strategic value is worth the cost in casualties and weapons , because the attacking Russians pay an even higher price. American officials aren’t so sure.

Elaborate Tales: As the Ukraine war grinds on, the Kremlin has created increasingly complex fabrications online  to discredit Ukraine’s leader, Volodymyr Zelensky, and undermine the country’s support in the West.

Targeting Russia’s Oil Industry: With its army short of ammunition and troops to break the deadlock on the battlefield, Kyiv has increasingly taken the fight beyond the Ukrainian border, attacking oil infrastructure deep in Russian territory .

Baltimore bridge collapse wasn't first major accident for giant container ship Dali

Propulsion failed on the cargo ship that struck the Francis Key Bridge in Baltimore early Tuesday as it was leaving port, causing it to collapse into the frigid Patapsco River. Its crew warned Maryland officials of a possible collision because they had lost control.

“The vessel notified MD Department of Transportation (MDOT) that they had lost control of the vessel” and a collision with the bridge “was possible,” according to an unclassified Department of Homeland Security report. “The vessel struck the bridge causing a complete collapse.”

An official speaking on condition of anonymity confirmed to USA TODAY that the DHS’ Cybersecurity and Infrastructure Security Agency is working with federal, state, and local officials “to understand the potential impacts of this morning’s collapse of the Francis Scott Key Bridge.”

Clay Diamond, executive director, American Pilots’ Association, told USA TODAY power issues are not unusual on cargo ships, which are so large they cannot easily course correct.

“It’s likely that virtually every pilot in the country has experienced a power loss of some kind (but) it generally is momentary,” Diamond said. “This was a complete blackout of all the power on the ship, so that’s unusual. Of course this happened at the worst possible location.” 

The ship in Tuesday's crash, Dali, was involved in at least one prior accident when it collided with a shipping pier in Belgium.

That 2016 incident occurred as the Dali was leaving port in Antwerp and struck a loading pier made of stone, causing damage to the ship’s stern, according to VesselFinder.com, a site that tracks ships across the world. An investigation determined a mistake made by the ship’s master and pilot was to blame.

No one was injured in that crash, although the ship required repair and a full inspection before being returned to service. The pier – or berth – was also seriously damaged and had to be closed.

VesselFinder reports that the Dali was chartered by Maersk, the same company chartering it during the Baltimore harbor incident.

The 9-year-old container ship had passed previous inspections during its time at sea, but during one such inspection in June at the Port of San Antonio in Chile, officials discovered a deficiency with its "propulsion and auxiliary machinery (gauges, thermometers, etc)," according to the Tokyo MOU, an intergovernmental maritime authority in the Asia-Pacific region.

The report provided no other information about the deficiency except to note that it was not serious enough to remove the ship from service.

Why did Dali crash into the Baltimore bridge?

Officials said Tuesday they’re investigating the collision, including whether systems on board lost electricity early Tuesday morning, which could be related to mechanical failure, according to a U.S. official who was not authorized to speak publicly.

Accidents at sea, known as marine casualties, are not uncommon, the source told USA TODAY. However, “allisions,” in which a moving object strikes a stationary one with catastrophic results, are far less common. The investigation of the power loss aboard the Dali, a Singapore-flagged vessel, will be a high priority.

In a video posted to social media, lights on the Dali shut off, then turned back on, then shut off again before the ship struck a support pier on the bridge.

Numerous cargo and cruise ships have lost power over the years.

The International Convention for the Safety of Life at Sea requires all international vessels to have two independent sources of electricity, both of which should be able to maintain the ship's seaworthiness on their own, according to a safety study about power failures on ships , citing the International Convention for the Safety of Life at Sea.

The Dali's emergency generator was likely responsible for the lights coming back on after the initial blackout, Diamond said.

“There was still some steerage left when they initially lost power,” he said. “We’ve been told the ship never recovered propulsion. The emergency generator is a diesel itself – so if you light off the generator, that’s also going to put off a puff of exhaust.”

Under maritime law, all foreign flagged vessels must be piloted into state ports by a state licensed pilot so the Dali's pilot is licensed by Association of Maryland Pilots .

Diamond described the incident based on information from the Maryland agency that licensed the pilot aboard the ship. His organization represents that group and all other state piloting agencies in the US.

“The pilot was directing navigation of the ship as it happened,” he said. “He asked the captain to get the engines back online. They weren’t able to do that, so the pilot took all the action he could. He tried to steer, to keep the ship in the channel. He also dropped the ship’s anchor to slow the ship and guide the direction.

“Neither one was enough. The ship never did regain its engine power.”

How big is the Dali ship?

The Dali is a 984-foot container vessel built in 2015 by Hyundai Heavy Industries in South Korea. With a cruising speed of about 22 knots – roughly 25 mph. It has traveled the world carrying goods from port to port.

The ship, constructed of high-strength steel, has one engine and one propeller, according to MarineTraffic.com.

The Dali arrived in Baltimore on Sunday from the Port of Norfolk in Virginia. Before that, it had been in New York and came through the Panama Canal.

It remains at the scene of the collapse as authorities investigate.

Who owns and operates the Dali?

It is owned by the Singapore-based Grace Ocean Pte Ltd but managed by Synergy Marine Group, also based in Singapore. It was carrying Maersk customers’ cargo, according to a statement from the shipping company.

“We are deeply concerned by this incident and are closely monitoring the situation,” Maersk said in the statement. 

Synergy, which describes itself as a leading ship manager with more than 600 vessels under its guidance, issued a statement on its website acknowledging the incident and reporting no injuries among its crew and no pollution in the water. There were two pilots on board and 22 crew members in all, according to Synergy, all of them from India.

USA TODAY reached out to Synergy on Tuesday, but the company did not immediately return a call seeking comment.
