Sphygmomanometer Definition. A sphygmomanometer is a device that measures blood pressure. It is composes of an inflatable rubber cuff, which is wrapped around the arm. A measuring device indicates the cuff's pressure. A bulb inflates the cuff and a valve releases pressure. A stethoscope is used to listen to arterial blood flow sounds.
When a sphygmomanometer is used, the cuff is inflated, usually around the upper arm, and the pressure is gradually released. A digital sphygmomanometer often operates at the touch of a button, and the blood pressure data is displayed on a digital screen. Many manual sphygmomanometers are also still in use, which usually require a medical professional to operate correctly.
