MICROANATOMY

Detailed explanation-1: -a stethoscope for listening to the sound the blood makes as it flows through the brachial artery (the major artery found in your upper arm).

Detailed explanation-2: -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.

Detailed explanation-3: -The brachial artery is the extension of the axillary artery starting at the lower margin of the teres major muscle and is the major artery of the upper extremity. The brachial artery courses along the ventral surface of the arm and gives rise to multiple smaller branching arteries before reaching the cubital fossa.

Detailed explanation-4: -Place the chosen cuff on either the patient’s arm. Place the stethoscope over the brachial artery. Inflate the cuff to a pressure of 30 mmHg above the level at which the radial pulse is no longer palpable. While slowly deflating the cuff, listen for Korotkoff phase I while watching the blood pressure gauge.
