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.
To measure arterial blood pressure, the cuff of the sphygmomanometer is usually wrapped around the arm so that it surrounds the brachial artery. Air is pumped into the cuff until the cuff pressure exceeds the pressure in that artery. As a result, the vessel is squeezed closed, and its blood flow stopped.
