MEDICAL PHYSIOLOGY

Detailed explanation-1: -For a manual blood pressure measurement, the care provider places a stethoscope over the major artery in the upper arm (brachial artery) to listen to blood flow. The cuff is inflated with a small hand pump. As the cuff inflates, it squeezes the arm. Blood flow through the artery stops for a moment.

Detailed explanation-2: -The blood pressure cuff is placed on the subject’s right arm, allowing 1 inch between the bottom of the cuff and the crease of the elbow. The brachial pulse is palpated just above the angle of the elbow (the “antecubital fossa").

Detailed explanation-3: -Blood travels from the heart into the subclavian artery which continues on down the arm as the axillary artery. The axillary artery travels deep in the arm pit and gives off several small branches which feed muscles and bones around the shoulder. The axillary artery continues down the arm as the brachial artery.
