What is the function of BP apparatus aneroid?

The BP (blood pressure) apparatus aneroid is a device used to measure blood pressure without the use of liquid. It consists of a cuff that wraps around the arm, a pressure gauge that indicates the pressure readings, and a bulb for inflating the cuff. As the cuff inflates and then deflates, the gauge measures the pressure in the arteries, providing systolic and diastolic readings. This device is commonly used in clinical settings for monitoring cardiovascular health.
