Aneroid sphygmomanometer with an adult cuff. A sphygmomanometer (pronounced /ËsfÉªÉ¡moÊmÉËnÉmÉ¨tÉr/. SFIG-moh-mÉ-NOM-i-tÉr) or blood pressure meter is a device used to. measure blood pressure, comprising an inflatable cuff to restrict blood. flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what. pressure blood flow is just starting, and at what pressure it is. unimpeded.
Measurement of Arterial Blood Pressure Cardiovascular Systemic arterial blood pressure usually is measured using an instrument called a sphygmomanometer. This device consists of an inflatable rubber cuff connected by tubing to a compressible bulb and a glass tube containing a column of mercury.hen the cuff pressure is approximately equal to the systolic blood pressure within the brachial artery, the artery opens enough for a small amount of blood to spurt through. This movement produces a sharp sound (Korotkoff's sound) that can be heard through the stethoscope.
