How to use different sphygmomanometers
1. Electronic sphygmomanometer
1. 20 days before measuring blood pressure Minutes, you can go to the toilet, holding back urine will have a certain impact on blood pressure, after that, sit at the table, do not exercise, smoke, etc.
2. After exhausting the air from the cuff of the electronic sphygmomanometer, tie it to the left or right arm, paying attention to be flush with the heart. And there can be no thick clothes such as sweaters, the cuff should be in contact with the skin or only a thin layer of clothing.
3. Open the start button of the electronic sphygmomanometer to measure, and then check the measurement time according to the manual of the electronic sphygmomanometer. The specific time depends on the manual of the electronic sphygmomanometer. different.
4. During the measurement, relax the arm, open the palm, and do not make a fist. Measure again after 3-5 minutes of rest, and take the average value as the result of this measurement. The best time to measure is 1 hour after getting up or 1 hour before going to bed.
2. Mercury sphygmomanometer
1. The sphygmomanometer should keep the same horizontal position as the arm and heart to be measured. Measure in the supine position.
2. Turn on the sphygmomanometer so that the mercury column reading drops to zero. After exhausting the air in the sphygmomanometer cuff, put it 2-3 cm above the elbow joint of the arm.
3. Tie the air sleeves, be careful not to tie them too tightly or too loosely. After feeling the throbbing of the brachial artery inside the cubital fossa, place the stethoscope on the brachial artery and tighten the air valve on the air cuff. Quickly pump up the pressure. When pumping up, the measurer should look at the mercury column of the sphygmomanometer, and keep the line of sight and the scale at the same level as possible.
4. Unscrew the gas valve to make the mercury drop slowly. When you hear the sound of the first pulse beat, the reading displayed at this time is the systolic blood pressure value. Continue to listen while deflating, until at a certain blood pressure scale, the pulse sound becomes weak or even disappears, and the blood pressure displayed at this time is diastolic blood pressure. The subject should remain calm before the measurement. After the measurement, the re-measurement should be performed at least 1 to 2 minutes later. The average value of the two measurements was selected as the measured blood pressure value.
III. Barometric sphygmomanometer
1. After installing the battery, connect the catheter and turn it on.
2. Tie the cuff. The length and width of the cuff airbag are very important for accurate blood pressure measurement. It is recommended that children, adults and obese people use cuffs of different specifications. The arm and the trunk are at 45°, the armband should be flat and tightly wrapped around the upper arm, the lower edge of the armband should be 2.5 cm above the elbow, and the balloon catheter and the middle finger should be in a straight line.
3. When sitting and measuring, the armband should be at the same level as the heart. When measuring in the supine position, the arm and the heart should be at the same level. No matter which position is taken to measure blood pressure, the palms are upwards and the arms are straight and relaxed.
4. Predict your highest blood pressure first, then hold the balloon with the other hand, squeeze hard to inflate and pressurize the armband, until it is about 30-40 higher than the predicted highest blood pressure. mmHg, and at the same time, the indicator light goes out. The maximum blood pressure does not exceed 300 mm Hg. After the compression is finished, the sphygmomanometer starts to measure automatically.
5. After the measurement, the display shows the highest blood pressure value (systolic blood pressure), the lowest blood pressure value (diastolic blood pressure) and the pulse rate. Then deflate and the measurement ends.
6. After waiting for 2 to 5 minutes, repeat the measurement on the same arm. Active shutdown or automatic shutdown. Record each blood pressure measurement and see a doctor or consult if necessary.
What should I pay attention to when measuring blood pressure at home
1. Because of the blood flow direction, the blood pressure measured by the left hand and the right hand is usually different. Usually, the blood pressure value of the left hand is slightly higher than that of the right hand, but the difference between 10 and 20 mmHg is normal. However, the highest measurement data should prevail when recording. If the difference between the two hands exceeds 40-50mmHg, it may be a blockage of blood vessels. It is best to consult a doctor to find out the cause.
2. It is not advisable to measure blood pressure only once. You should measure your blood pressure several times a day and record it in order to understand the changes in your blood pressure within a day.
3. The commercially available sphygmomanometers are mostly electronic, and their measurement results are usually slightly higher than those of traditional mercury sphygmomanometers. The electronic sphygmomanometer is divided into two types: the wrist type and the arm type. Although the wrist type is more convenient to use, it is usually farther away from the heart, and the greater the difference in measurement results. It is recommended to test on the spot when purchasing. If the results of the arm type and the wrist type are not very different, both can be used; if the difference is large, the arm type is better.
4. Before and after using the mercury sphygmomanometer, you should always pay attention to check the blood pressure status, keep the scale clear, the column should be cleaned regularly with a strip, and there should be no air bubbles when the pressure is about 200mmgH. Air bubbles should be stopped for inspection and maintenance.
5. The traditional mercury sphygmomanometer will be affected by thermal expansion and contraction, and should be calibrated and reset to zero every six months on average.
6. The electronic sphygmomanometer will be affected by the aging of components, and it needs to be calibrated once a year on average.
