Pulse Rate The What, Why, and How What is a pulse? ▪ Pulse is defined as “the pressure of the blood pushing against the wall of an artery as the heart beats and rests” ▪ It is a throbbing of the arteries that is caused by the contractions of the heart. ▪ The pulse is more easily felt in arteries that are fairly close to the skin and can be pressed against a bone by the fingers. ▪ Correlation between heart health and physical condition Why is this measurement important ▪ The heart is one of the most important muscles in your body. ▪ In so many words, it’s a way to keep track of the performance of your heart ▪ Pulse (Heart rate) is a way to measure how hard your heart is working ▪ The higher resting HR, the harder the heart is working ▪ The lower resting HR, the easier the heart is working Normal Pulse Ranges ▪ Adult: 60 – 100 ▪ Infants: 100 – 160 ▪ An infant heart cannot stretch very much due to immature muscle fibers. It has to pump at a faster rate to maintain blood flow through the body. Abnormal Pulse Ranges ▪ Tachycardia: pulse over 100 bpm (except in children) ▪ Bradycardia: pulse under 60 bpm ▪ Arryhthmia: irregular or abnormal rhythm, usually caused by a defect in the electrical conduction pattern of the heart. ▪ https://youtu.be/DLmmN0jy-s0 Variables that impact pulse Good Variables Bad Variables Exercise Caffeine beverages Meditation Sugary foods Healthy Diet Smoking High Stress Levels Obesity Alcohol consumption How do you measure pulse (heart rate)? https://youtu.be/3YOap5k0R_8 Major sites pulses are felt ▪ Temporal: at the side of the forehead ▪ Carotid: on the side of the neck ▪ Brachial: inner aspect of the bicep near the crease of the elbow ▪ Radial: at the inner aspect of the wrist, above the thumb ▪ Femoral: at the inner aspect of the upper thigh ▪ Popliteal: behind the knee ▪ Dorsalis pedis: at the top of the foot arch ▪ Posterior tibial: below the medial side of the ankle Temporal Pulse Carotid Pulse Brachial Pulse Radial Pulse Femoral Pulse Popliteal Pulse Posterior Tibial Pulse Dorsalis pedis Pulse https://youtu.be/8F 5qE8kjjUA
