blood pressure monitor, also known as a sphygmomanometer, is a medical device used to measure blood pressure in the arteries. It is essential tool for diagnosing and managing conditions related to blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure).
Components of a Blood Pressure Monitor:
- Cuff: A flexible band that wraps around the upper arm (or wrist, in some models) and inflates to constrict blood flow in the artery.
- Pressure Gauge: An analog dial or digital display that shows blood pressure readings, typically measured in millimeters of mercury (mmHg).
- Bulb or Pump: A manual or automatic mechanism used to inflate the cuff.
How Blood Pressure is Measured:
Blood pressure is reported as two numbers:
- Systolic Pressure: The first, higher number, which measures the pressure in the arteries when the heart beats and pumps blood.
- Diastolic Pressure: The second, lower number, which measures the pressure in the arteries when the heart is at rest between beats.
