Sphygmomanometer

A sphygmomanometer is a blood pressure measuring device. It's made out of an inflated rubber cuff that wraps over your arm. The pressure of the cuff is shown via a measuring device. The cuff is inflated by a bulb, and the pressure is released via a valve. A stethoscope is used to listen to the sounds of arterial blood flow. 

As the heart beats, blood pumped through the arteries causes a rise in pressure, known as systolic pressure, followed by a reduction in pressure as the ventricles of the heart prepare for another beat. This low pressure is referred to as the diastolic pressure.

What is the importance of a Sphygmomanometer?

To accurately diagnose hypertension, it is critical to be well-trained in blood pressure measuring methods and to have an accurate, dependable device. And  a Sphygmomanometer is the most accurate device to measure blood pressure.

Types of a Sphygmomanometer

There are three types of sphygmomanometers used to measure human blood pressure. 

• Mercury sphygmomanometer. Mercury sphygmomanometer is a conventional and time-tested way of measuring blood pressure.
  The device is made up of an inflated bladder and a mercury column. Various mercury levels in the column are caused by different pressures. Once the column is made, it is not necessary to recalibrate it to their exact specifications.
• Aneroid Sphygmomanometer. The aneroid sphygmomanometer is a device comprised of a spring mechanism and a metal membrane that transforms the signals from the cuff and controls a needle in the gauge. It stands on the stans or walls. Because there is no liquid present, this gadget may be readily transferred from one area to another. Because these devices require calibration checks, the findings are imprecise. Before using the needle, it must be kept at zero. Calibrations are performed on a regular basis to ensure accurate findings.
• Digital Sphygmomanometer. The digital sphygmomanometer comes in useful when you want to test your blood pressure at home without any preparations, including diastolic and systolic blood pressure. Simply insert the rubber node into the monitor's hole and wrap the cuff over your upper arm; when you press the button, it will measure your blood pressure and heart rate using oscillometric detection. The monitor has an audio device that will inform you of the results in accordance with WHO guidelines. It is portable and convenient, that it can be charged, and that we can check average results.
