Pulse and Respiration
Pulse and Respiration
Measuring and Recording the Pulse
Definition of Pulse:
Pulse is defined as the pressure that the blood exerts on the arterial wall as the heart beats and rests.
Pulse Sites
There are multiple sites on the body where pulses can be measured. These include:
Carotid: Located in the neck
Brachial: Located in the upper arm
Apical: Located in the chest
Radial: Located in the wrist on the thumb side
Femoral: Located in the groin
Popliteal: Located behind the knee
Pedal: Located on the arch of the foot
Beats per Minute
Pulse Expression:
The pulse rate is always expressed as a single number indicating the beats per minute, such as 76 or 88.
Pulse Rate Calculation
Rate Definition:
The rate is defined as the number of beats in a minute.
To obtain this rating, one can count and multiply the results:
Measure for 15 seconds, then multiply by 4
Measure for 30 seconds, then multiply by 2.
Characteristics of Pulse
Rhythm and Strength:
Evaluate whether the pulse is regular or irregular.
Assess the strength of the pulse: is it strong, weak, or thready (barely able to feel) under the fingers?
Factors that Change Pulse Rate
Various factors can lead to changes in pulse rates, including:
Stress
Exercise
Weight
Age
Illness/Pain
Pregnancy
Medication
How to Obtain a Radial Pulse
Instructions on how to obtain a pulse in the wrist are provided through an instructional video.
Normal Pulse Rates
Adults:
A normal pulse rate for adults ranges from 60 - 80 beats per minute.
Pulse is typically taken radially.
Athletes may have a significantly lower pulse rate.
Infants:
A normal pulse rate for infants ranges from 100 - 160 beats per minute.
The smaller the infant, the higher the rate.
Pulse is usually taken apically or in the brachial artery.
Children:
Children aged 1 - 8 or up to puberty have a normal pulse rate from 80 - 100 beats per minute.
Pulse can be taken apically (on the chest) or radially as they grow older.
Respirations
Obtaining Respiratory Rate:
Instructions to learn how to obtain respiratory rates are introduced.
Observational Considerations in Respirations
Altered Breathing:
Individuals may alter their breathing patterns if they are aware they are being observed.
They often try to mimic the observer’s respirations.
It is necessary to make counting less obvious, similar to how pulse is expressed as a rate per minute.
Counting the Respirations
Counting Technique:
To unobtrusively count respirations, it is recommended to take the pulse rate simultaneously:
Count the pulse for 15 seconds, then shift the gaze to the chest to count the rise or fall for another 15 seconds.
Tips for Counting Respirations
Instructions and additional tips for how to accurately count respiratory rates are presented.
Normal Respiratory Rates
Adults:
A normal respiratory rate for adults is 12 - 20 breaths per minute.
Infants:
A normal respiratory rate for infants ranges from 18 - 34 breaths per minute.
Children:
For children aged 1 - 8 or up to puberty, the normal respiratory rate is 16 - 28 breaths per minute.
Relation Between Pulse and Respiratory Rates
Breathing and Heart Rate Correlation:
In general, respirations can be approximately 1/4 of the heart rate.
Example: If the pulse rate is 80, the respiratory rate would be approximately 20.
Practical Application
Your Turn Activity:
Students are encouraged to first find their own pulse, which is easiest when locating it on oneself.
Once confident in locating the radial pulse, students should practice finding pulses in others within the classroom.
Note: Use hand sanitizer before touching another person!
