Pulse is measuring heart beat by palpating a peripheral artery by the fingertip (with the exception of using the thumb). Sometimes, there is delay, which is indicative of pathology.
Pulses can be palpated at any place that allows an artery to be compressed against a bone, including:
Head and neck:
Carotid artery, located in the neck, between the anterior border of the sternocleidomastoid muscle, above the hyoid bone, and laterla to the thyroid cartilage. It should be palpated gently while the patient is sitting or lying down. Stimulating its baroreceptors with low palpation can provoke severe bradycardia, or even stop the heart in sensitive patients. A patient's 2 carotid arteries should NOT be palpated at the same time, as it may limit blood flow to the head, possibly causing fainting or brain ischemia
Radial artery, located on the lateral of the wrist, at the anatomical snuffbox, commonly measured using 3 fingers, so the finger closest to the heart occludes the pulse pressure, the middle finger otains a crude estimate of blood pressure, and the ring finger is used to nullify the effect of the ulnar pulses as the 2 arteries are connected via the palmar arches
Apical pulse, located at the 5th intercostal space, 1.25cm lateral to the midclavicular line. Unlike other pulse sites, it is not under an artery, but at the apex of the heart
Femoral artery, located at the groin, in the inner thigh, at the mid-inguinal point, halfway between the pubic symphysis and ASIS (anterior superior iliac spine)
Popliteal artery, located above and behind the knee, in the popliteal fossa, found by holding the bent knee. The knee is bent at apprximately 124 degres, and the doctor holds it in both ahdns to find the popliteal artery in the pit behind th eknee
Posterior tibial artery, located on the medial side of the ankle joint, over Pimenta's Point, where 3 fingers are placed at the midpoint of an imaginary line drawn between the bony prominence of the medial maleolus, and the insertion of the achilles tendon
HR can also be measured by auscultating the heart beat using a stethoscope.
What is pulse? It's the beating of the heart that you're feeling, right?
Yep. So you're feeling the heart beat peripherally.
How do you feel the heart beating peripherally?
So you press the artery against a bone. You can do this in the head, at the carotid artery in the neck. You can do this in the arm, at the brachial artery inside the elbow, radial artery at the wrist. You can also do this in the feet, at the femoral artery at the groin, popliteal artery behind the knee, posterior tibial artery near the ankle joint, and dorsalis pedis artery on the foot.
Rate, is in beats per minute (bpm), representing heart rate. It has the extremities of bradycardia and tachycardia
Rhythm can either be:
Regularly irregular, is a regular but intermittent pulse, and can be caused by:
2nd degree AV block
Irregularly irregular, which is irregularly and intermittent pulse, can be caused by:
Volume (aka amplitude, expansion, size of pulse), is the degree of expansion of the artery during diastole and systole. It includes:
Hypokinetic pulse (aka weak pulse), indicates narrow pulse pressure. It can be caused by:
