Detailed explanation-2: -To measure blood pressure, your doctor uses an instrument call a sphygmomanometer, which is more often referred to as a blood pressure cuff. The cuff is wrapped around your upper arm and inflated to stop the flow of blood in your artery.

Detailed explanation-3: -Rest the patient’s arm on a surface that is level with their arm. Place the stethoscope over the brachial artery (in the bend of the elbow) and listen to the pulse (Figure 2). Pump up the cuff slowly and listen for when the pulse disappears. This is an indication to stop inflating the cuff.

Detailed explanation-4: -The bell of the stethoscope is suggested because it is used for low-pitched sounds like blood pressure.
