How to treat sphygmomanometer

If you want to know the measurement results of sphygmomanometer, it is better to know the measurement method of sphygmomanometer first. I have used a nine-amp sphygmomanometer, and the measurement method is very simple. The traditional measurement method is: take supine position or sitting position, and the arm (usually the right upper limb) should be bare, flush with the heart and slightly abduction.

Steps:

1. First turn on the switch for adjusting mercury to see if it is in the standard position (key! Then, stick the middle part of the cuff airbag of the sphygmomanometer on the brachial artery (stick it outward) and stick it on the upper arm near the skin. The lower edge of the cuff is 2 ~ 3 cm away from the cubital fossa, and it should not be too loose, so it is advisable to insert a finger.

2. Touch the pulse of the brachial artery at the cubital fossa, then put the chest radiograph of the stethoscope (preferably a bell-shaped chest radiograph) on the brachial artery at the cubital fossa, and gently press the chest radiograph of the stethoscope to make it closely contact with the skin. Put on a stethoscope and inflate the cuff.

3. While inflating, auscultate (at this time, you don't need to hold the cuff by hand, you can do it naturally). After hearing no pulsation of brachial artery, raise the mercury column by 2.7 ~ 4 kPa (20 ~ 30 mm Hg) and slowly release the air in the cuff. When you hear the first sound, the displayed mercury column value is systolic blood pressure; After that, the sound gradually weakens, and the mercury column value displayed when the sound disappears is diastolic pressure, and the difference between them is pulse pressure.

4. After completing the pressure measurement, wait for 2 minutes, repeat the pressure measurement on the same arm, and take the average of the two measurements.

Attention should be paid to: a. Normal blood pressure standard: systolic blood pressure < 18.7 kPa (140mmhg) and diastolic blood pressure <12kPa (90mmhg). Write it as: systolic blood pressure/diastolic blood pressure = 140/90 mmHgb. The premise is to measure correctly under the condition of excluding drugs, emotions and physiological conditions. If the blood pressure measured more than three times on different days exceeds the normal blood pressure standard, it can be diagnosed as hypertension. Because the blood pressure difference between the two upper limbs can be 1.3 ~ 2.7 kPa (10-20 mm Hg), the blood pressure of the upper arm of the same patient should be fixed. If the blood pressure of the two arms is not much different, the blood pressure of the right upper arm should be fixed.

In fact, in order to save time and the accuracy of the measurement results, I personally think it's better to buy an intelligent sphygmomanometer, such as the Jiu 'an sphygmomanometer I'm using now. It is very convenient, without too many complicated operations, and it also supports voice broadcast. Very scientific and accurate, really feel very practical!
