what is measured using a sphygmomanometer:
Among the many common tools used in a doctorâs office is one which weâre all familiar with, but whose real name is little-known. That device is the sphygmomanometer, which is used to measure blood pressure. The sphygmomanometer has been in wide use since the early 20th century, and consists of a cuff placed around the arm, as well as a device to measure the pressure at which blood flows freely, and the pressure at which blood flow is restricted.
