What is the name of the device used to measure blood pressure?

The device used to measure blood pressure is called a sphygmomanometer. This instrument typically consists of an inflatable cuff that is wrapped around the arm and a measuring unit that displays the pressure readings. When the cuff is inflated, it compresses the artery, and as the cuff is slowly deflated, the device measures the pressure in the artery, providing two readings: systolic and diastolic pressure. This is crucial for assessing cardiovascular health and diagnosing conditions such as hypertension.

Other devices listed have different specific functions. A thermometer measures body temperature, a pulsometer is used to measure heart rate or pulse, and an electrocardiograph records the electrical activity of the heart. Each of these instruments serves important roles in medical diagnostics but does not measure blood pressure.
