How to use a sphygmomanometer? How to use a sphygmomanometer?

Many people have sphygmomanometers at home. Some people just bought it and read the instructions, but they don't particularly know how to operate and how to measure blood pressure. The following is how to use the sphygmomanometer.

Use of sphygmomanometer

Patients with high blood pressure at home will be advised by doctors to buy a sphygmomanometer at home so as to measure their blood pressure in time. Sphygmomanometers are generally electronic sphygmomanometers and mercury sphygmomanometers used in hospitals. Mercury sphygmomanometer can measure accurately, but it will be more troublesome to operate and cannot be used by one person alone. The electronic sphygmomanometer is simple to operate, but the data is not particularly accurate. You can choose a sphygmomanometer according to different situations. Here I teach you how to use a sphygmomanometer.

How to use electronic sphygmomanometer;

You can go to the toilet 20 minutes before your blood pressure is measured. Holding your urine will have a certain effect on blood pressure. After that, I sat at the table and didn't exercise or smoke.

/kloc-after 0/5 minutes, relax, then exhaust the cuff of the electronic sphygmomanometer and tie it on the left arm or right arm, paying attention to it, flush with the heart. And you can't have thick clothes such as sweaters. The cuffs should be in contact with the skin or only thin clothes.

Turn on the start button of the electronic sphygmomanometer to measure, and then look at the measuring time according to the instruction manual of the electronic sphygmomanometer, which shall prevail. (The time will vary from model to model. )

During the measurement, relax your arms, open your palms, and don't make a fist. Take a rest for 3-5 minutes and then measure it again. The average value is the result of this measurement. The best measurement time is 1 hour after getting up or 1 hour before going to bed.

How to use mercury sphygmomanometer

1. Correct posture: The sphygmomanometer should keep the same horizontal position with the arm and heart to be measured. Subjects can choose to sit or lie down for measurement.

2. Turn on the sphygmomanometer and reduce the mercury column reading to zero. After exhausting the air in the cuff of the sphygmomanometer, put it 2 ~ 3 cm above the elbow joint of the arm (it is best to choose the left arm for measurement, because the left arm is close to the heart and the relative measurement data is relatively stable).

3. Fix the cuffs (not too tight or too loose). After the brachial artery pulsates inside the cubital fossa, put the stethoscope head on the brachial artery and tighten the air valve on the cuff. Fast pumping and pressure measurement. When pumping air, the measurer should pay attention to the mercury column of the sphygmomanometer (pay attention to keeping the line of sight and scale on the same horizontal line as possible).

4. Unscrew the air valve and let the mercury drop slowly. When you hear the sound of the first pulse beating, the reading displayed at this time is the systolic blood pressure value. Continue listening while deflating until the pulse sound at a certain blood pressure scale weakens or even disappears, and the displayed blood pressure is diastolic pressure. Subjects should keep calm before measurement. After measurement, re-measure at least after 1 ~ 2 minutes. The average value of two times is selected as the measured blood pressure value.

5. Safe disposal of mercury sphygmomanometer:

(1) After using the sphygmomanometer, tilt the sphygmomanometer about 45 to the right of the mercury bottle, and turn off the switch of the mercury storage bottle after the mercury completely returns to prevent the mercury from flowing out.

(2) When the switch of the mercury storage bottle is not turned on, do not inflate or pressurize the rubber bag. Because when there is air in the bag, turning on the switch of the mercury storage bottle is easy to cause Gong to discharge and cause an accident.

(3) If there is any problem with the sphygmomanometer, it should be sent to a professional department for maintenance. Unauthorized maintenance can easily lead to mercury outflow and affect health.

(4) The sphygmomanometer should be placed horizontally in a stable and firm place, with an ambient temperature of -20℃ ~+35℃ and a relative humidity of ≤80%.

Small knowledge of sphygmomanometer

Sphygmomanometer mainly includes auscultation sphygmomanometer and oscillometric sphygmomanometer. Auscultation includes manual auscultation and automatic auscultation. Mercury sphygmomanometer (manometer) and spring sphygmomanometer (manometer) are early manual auscultation sphygmomanometer, and now there are digital display sphygmomanometer, light display sphygmomanometer and liquid crystal sphygmomanometer. Auscultation automation technology is difficult.

The automation of Coriolis auscultation will be the main direction of sphygmomanometer development. Automatic auscultation sphygmomanometer will make blood pressure measurement more convenient and accurate.

Oscillographic method, also known as oscillation method, is simply to obtain the oscillation wave generated during deflation and convert it into blood pressure value through a certain algorithm. . Most electronic sphygmomanometers are designed according to the oscillometric principle. Electronic sphygmomanometer can be divided into upper arm, wrist and finger.

Why can drinking celery juice lower blood pressure?

1. celery juice contains apigenin, which can maintain the normal function of blood vessels, enhance elasticity and relieve the tension of the central nervous system, thus lowering blood pressure.

2. High sodium ion content in blood will lead to hypertension, while potassium ion content in celery juice is higher than sodium ion content. celery juice can promote the discharge of sodium ion in the body, which has the functions of protecting blood vessels and lowering blood pressure.

What should pregnant women do if their blood pressure is unstable?

Is it normal that blood pressure is sometimes high and sometimes low after pregnancy?

Experts tell us that during pregnancy, due to physical reasons, blood pressure will increase slightly, decrease in the middle period, return to normal in the later period, and blood pressure will fluctuate throughout pregnancy.

Of course, these changes are generally within a certain range and vary according to everyone's physique. Pregnant mothers can learn more information by consulting a doctor.

It can be seen that the blood pressure of pregnant women will be unstable within a certain range, which is normal, and pregnant mothers do not need to worry. In addition, dizziness and palpitation are also symptoms of some pregnant women, which may be anemia during pregnancy or temporary hypoxia.

When a pregnant mother finds that her blood pressure is wrong at home, or suddenly has symptoms of hypertension or hypotension, she can go to the hospital for a detailed examination first. Don't worry too much. Doctors will explain everything and tell them how to treat it.
