- The gauge: This is the device that shows the blood pressure readings on a dial or digital display.
- The pump: This is the mechanism that inflates the cuff with air.
- The stethoscope: In manual blood pressure machines, a stethoscope is used to listen to the sound of blood flowing through the artery, allowing the user to take an accurate reading.
Each component plays a crucial role in ensuring accurate and reliable blood pressure readings. The cuff is tightly wrapped around the upper arm, while the gauge displays the pressure reading in millimeters of mercury (mmHg). The pump inflates the cuff, and the stethoscope allows the user to listen to the blood flow, making adjustments as needed.
Types of Blood Pressure Machines
There are several types of blood pressure machines available, each with its own advantages and disadvantages:
- Mercury sphygmomanometer: This is the traditional blood pressure machine that uses a mercury column to measure blood pressure. It is no longer widely used due to environmental concerns.
- Aneroid sphygmomanometer: This type of machine uses a series of coils to measure blood pressure, making it more portable and maintenance-free.
- Digital sphygmomanometer: This is the most common type of blood pressure machine, using electronic sensors and a display to show blood pressure readings.
