When you have a medical examination in the hospital or the medical examination center. Usually, we use an aneroid sphygmomanometer to measure blood pressure.From 2020, it is not convenient to go to the hospital, and you can buy some personal medical tools to evaluate your body. The aneroid sphygmomanometer is the one that you can buy. Maybe you still don’t know how to use it.


In this article, we will let you know the details when using the aneroid sphygmomanometer. The information will as follow:


The function of the aneroid sphygmomanometer

The using precautions of the aneroid sphygmomanometer


1.The function of the aneroid sphygmomanometer


An aneroid sphygmomanometer is a device for measuring blood pressure. It consists of an inflatable rubber cuff that is wound around the arm. The measuring device indicates the pressure of the cuff. The bulb expands the cuff and releases pressure from the valve. The stethoscope is used to listen for arterial blood flow.


The pressure we measured, is not just one pressure, actually two kinds of pressures, the first one is the systolic pressure, another one is the diastolic pressure


As the heartbeats, the blood forced through the arteries causes a pressure called systolic pressure to rise, which is then lowered as the heart's ventricles prepare to beat again. This low pressure is called diastolic pressure.


The cuff of the aneroid sphygmomanometer inflated to a much higher systolic pressure than expected. As the valve opens, cuff pressure decreases slowly. When the cuff pressure is equal to the arterial systolic pressure, blood begins to flow through the cuff, producing turbulent blood flow and audible sounds. Using a stethoscope, you can hear these sounds and record the pressure on the cuff. The sound of blood flow will continue until the cuff pressure drops below diastolic blood pressure. The pressure at the cessation of blood flow indicates diastolic pressure.


These two kinds of blood pressure can evaluate your body, whether you have hypertension or other diseases.


2.The using precautions of the aneroid sphygmomanometer

To begin blood pressure measurement, use a properly sized blood pressure cuff. If the rubber cuff is small, the result will not be accurate.


Rapidly inflate the aneroid sphygmomanometer cuff to 180mmHg. After that, release air from the cuff at a moderate rate.


Listen with your stethoscope and look at the dial or mercury gauge. The pressure when you hear the first knock sound is systolic pressure. When the knocking sound disappears, at that moment, the pressure showed on the gauge it the diastolic blood pressure.


Record the pressures for each side of the arm, and notice the differences.


Alarming, when the blood pressure above the 180/120mmhg or higher.


The children may have higher blood pressure, which is usual.


When testing, do not bend your arms and keep your arm relax.


Don't place the cuff over clothing.


Keep attention to those precautions, and you will be able to use the aneroid sphygmomanometer.
