Question

Quizplus · Accepted Answer

A sphygmomanometer is a device used to measure blood pressure. It consists of an inflatable cuff, a bulb to inflate the cuff, and a gauge to measure the pressure within the cuff. The cuff is wrapped around the upper arm and inflated until it compresses the brachial artery, stopping the flow of blood. The pressure at which the blood flow resumes is the systolic pressure, and the pressure at which the sound of blood flow disappears is the diastolic pressure. These values are used to determine a person's blood pressure reading.
