Description
A sphygmomanometer is a medical device used to measure blood pressure. It typically consists of an inflatable cuff, a pressure gauge, and a mechanism for inflation. Here's a breakdown of its components and how it works:
-
Inflatable Cuff: This is wrapped around the upper arm (or sometimes the wrist or thigh) and inflated to a pressure higher than the systolic blood pressure (the pressure in the arteries when the heart beats and pumps blood). The cuff is usually made of durable fabric with a closure mechanism to secure it in place.
-
Pressure Gauge: The pressure gauge is typically a dial with a needle that indicates pressure in millimeters of mercury (mmHg). Modern digital sphygmomanometers may display the pressure digitally. The gauge measures the pressure exerted by the cuff on the brachial artery in the arm.
-
Inflation Mechanism: Traditionally, sphygmomanometers have a hand-operated bulb or a manual pump to inflate the cuff. When squeezed, the bulb or pump increases the pressure in the cuff. However, there are also automatic or electronic versions that inflate the cuff automatically at the press of a button.
-
Release Valve: This allows for controlled release of pressure from the cuff once the measurement is complete. It is crucial for accurate readings and to avoid discomfort or injury to the patient.
How It Works:
To take a blood pressure measurement using a sphygmomanometer, the cuff is wrapped around the upper arm and positioned over the brachial artery. The cuff is inflated until it compresses the artery enough to stop blood flow. Then, the pressure is gradually released while a stethoscope is used to listen for the return of blood flow. The pressure at which the first sound of blood flow is heard (the systolic pressure) and the pressure at which the sound disappears (the diastolic pressure) are recorded. These measurements provide important information about the health of the cardiovascular system.
