The specific steps of using blood pressure meter
Whether sitting or supine position, blood pressure should be placed at the level of the heart, and keep the same level of arms and heart. The correct posture, relax, keep breathing evenly.
1 Hold down the button to open the mercury blood pressure meter.
2 Loosen the bleed valve on the balloon.
3 Out of gas in the cuff.
4 Mercury valve for opening mercury blood pressure meter.
5 Cuff size should be appropriate, cuff air package should be at least 80% upper arm. Attach cuff at were upper arm, cuff lower edge should be 2-3 cm away from the elbow, cuff and heart at the same level.
6 Tie cuff, tightness in can accommodate two refers to the appropriate.
7 The right tie cuff, connecting pipe should be at the top of the side arm, the stethoscope chest piece of brachial artery at the elbow fossa. Regardless of the position of the body, the blood pressure meter should be placed at the heart level.
8The stethoscope in the ear.
9 Tighten the bleeder valves repeatedly squeeze the rubber balloon to cuff inflation pressure increases, the pressure inside the balloon should be sent to the radial artery pulse disappears and rises again 30mmhg, then at a constant rate (2-6mmHg seconds) slow deflated, slow heart rate when the outgassing rate is slow. Diastolic blood pressure to get a quick release to zero.
10 Systolic blood pressure (high pressure) reading: in slowly deflated relief when blood vessels when the first time I heard the sound when mercury column height that is representative of the systolic blood pressure.
11 Diastolic blood pressure (low pressure) reading: continue to deflate, the blood vessels, the sound suddenly change from strong to weak or voice suddenly disappeared when the mercury column height that is representative of the diastolic blood pressure
12 Diastolic blood pressure (low pressure) reading: continue to deflate, the blood vessels, the sound suddenly change from strong to weak or voice suddenly disappeared when the mercury column height that is representative of the diastolic blood pressure
