   Edit:管理员   Browse:1055  Date:2017/2/22 

1. The correct position: the sphygmomanometer should be measured with the arm, the heart to maintain the same level. Subjects can choose to sit or lie to measure.

2. Open the sphygmomanometer so that the reading of the mercury column drops to zero. After the air in the cuff of the sphygmomanometer, the sleeve is set at 2 to 3 cm above the elbow of the arm (the left arm is selected as the left arm, and the relative measured data is relatively stable).

3. Tighten the gas sleeves (do not tie too tight or too loose), in the elbow fossa inside the brachial artery after the beating, the stethoscope on the brachial artery, tighten the gas valve on the gas valve. Fast calorie. In the cheer, the surveyor should be watching the blood pressure monitor mercury column (note the line of sight and scale as much as possible to maintain the same level)

4. Unscrew the gas valve so that the mercury slowly drops. When you hear the sound of the first beat, the reading is the systolic blood pressure. Continue to hold the side to listen to, until in a blood pressure scale, pulse sounds weakened or even disappear, then show the blood pressure for diastolic blood pressure. Subjects should remain calm before measuring. After measurement, should be at least 1 to 2 minutes after the re-test. Select the average of the two times as the measured blood pressure value.

5. Mercury sphygmomanometer safe disposal:
(1) After the use of the sphygmomanometer, the sphygmomanometer should be tilted about 45 ° to the right side of the mercury bottle, and the mercury can be completely returned to close the switch of the mercury storage bottle to prevent mercury from flowing out.
(2) Do not inflate or press the rubber bag when the switch is not open. Because the air inside the bag when the mercury switch to open the switch, easily lead to tribute, causing the accident.
(3) If there is a problem with the sphygmomanometer, the professional department should be repaired. Unauthorized repair easily lead to mercury outflow, affecting your health.
(4) the sphygmomanometer should be placed in a stable and stable place, the ambient temperature -20 ℃ ~ +35 ℃, relative humidity ≤ 80%.
