An Aneroid Blood Pressure Machine is a manual blood pressure measuring device that utilizes an aneroid gauge to determine blood pressure levels. It is commonly known as an aneroid sphygmomanometer. The term "aneroid" refers to the absence of liquid within the gauge; instead, it employs a mechanical mechanism to measure pressure.
Key components of an aneroid blood pressure machine include:
-
Aneroid Gauge: The gauge has a dial that displays blood pressure readings in millimeters of mercury (mmHg). It typically consists of a needle that moves along the scale as pressure changes.
-
Cuff: The inflatable cuff is wrapped around the patient's upper arm. It is connected to the gauge via tubing.
-
Bulb: A hand-operated bulb (BP bulb) is used to inflate the cuff, creating pressure around the arm.
-
Valve: A release valve allows for controlled deflation of the cuff.
Healthcare professionals use aneroid blood pressure machines to manually measure blood pressure by listening to Korotkoff sounds with a stethoscope. This method is commonly employed in clinical settings and is valued for its accuracy and reliability when performed by trained practitioners.
