How to measure blood pressure with sphygmomanometer

It's good to take blood pressure regularly. However, many unfortunate people suffer from "angels in white's hypertension", which is an anxiety symptom caused by high blood pressure when approaching a doctor with a stethoscope. Taking blood pressure at home will eliminate this anxiety. You can estimate your average blood pressure by measuring it every day in your life. There are many digital blood pressure measuring devices on the market. The cheapest-arguably the most reliable 3354 instrument is the sphygmomanometer, also called sphygmomanometer, which is the same as that used by doctors. Here's how to use it at home.

Assemble equipment.

Sit down and turn on the blood pressure meter. Sit at the dining table or desk, so that you can easily assemble the required parts. Take out the cuff, stethoscope, pressure gauge and rubber ball (also called "inflatable bag") from the box and carefully straighten out all kinds of pipes.

Raise your arms to the height of your heart. Raise your arms so that when you bend your elbows, they will be flush with your heart. This can ensure that the blood pressure measurement results will not be too high or too low. It is also important to support your arm during the measurement, so make sure that your elbow is placed on a stable plane.

Lean on a solid plane.

Wrap the cuff around your arm. Most cuffs have shackles, which can easily fix the cuffs. If the clothes are long sleeves or thick sleeves, you need to roll up the sleeves first, because there can only be a very thin layer of cloth under the cuffs at most. The lower edge of the cuff is about an inch from the elbow.

Some experts suggest measuring the blood pressure of the left hand; Other experts suggest testing both arms. But if you are right-handed, take your left blood pressure for the first time, and vice versa.

Be sure to wrap the cuffs tightly, but not too tightly. If the cuff is too loose, the arterial blood flow cannot be cut off correctly, resulting in a low blood pressure reading. Tight cuff will cause "cuff hypertension", which will lead to high blood pressure reading.

Put the wide head of the stethoscope on your arm. The auscultation head (also called diaphragm head) should be placed inside the arm and attached to the skin. The edge of the auscultation head should be just below the cuff and placed on the brachial artery. Gently put the stethoscope earplug into your ear.

Don't put your thumb on the auscultation head. Your thumb has its own pulse, which will interfere with your blood pressure measurement.

The best way is to fix the auscultation head in place with the index finger and middle finger. In this way, you should not hear the banging sound before you start inflating the cuff.

Clamp the pressure gauge on a stable horizontal workbench. If the pressure gauge is clamped on the cuff, don't clamp it up, just lean on something stable, such as a hardcover book. So you can put it in front of you and see it more easily. It is important to install the pressure gauge correctly.

Before starting to measure blood pressure, make sure that the light is strong enough to see the pointer and scale of the pressure gauge.

Hold the rubber ball and tighten the valve. Before starting the measurement, the valve needs to be completely closed. This can ensure that there will be no air leakage when inflating, otherwise the reading will be inaccurate. Tighten the valve clockwise until it feels unable to turn.

It is also important to avoid screwing the valve too tightly, otherwise, the valve will open too hard and bleed too fast.
