Methods and steps of blood pressure measurement Methods and key points of blood pressure measurement

1, before measurement: When measuring blood pressure, the patient must be in a quiet state, rest for 20 ~ 30 min after exercise, and check the sphygmomanometer.

2. Prepare the materials, bring them to the bedside, check and explain them, and obtain cooperation.

3. The patient takes a sitting position or a lying position, exposes one arm, rolls the sleeve to the shoulder, straightens the elbow, and palms up.

4, flat sphygmomanometer, open the lid, open the mercury tank switch.

5. Place the middle part of the cuff airbag on the elbow socket, with the lower end of the cuff 2 ~ 3 cm away from the elbow socket, and wrap it flat on the middle part of the upper arm without folding, and the tightness should be suitable for 1 finger.

6. Put the chest radiograph of the stethoscope close to the brachial artery, close the valve, inflate until the brachial artery pulsation disappears, and then make the mercury column rise by 20 ~ 30 mmHg. 7. Slowly deflate (decrease by 4mmHg per second). The first pulsation sound of stethoscope refers to systolic pressure, and the pulsation sound weakens or disappears to refer to diastolic pressure.

7. organize the sphygmomanometer.

8, patient placement, bed unit.

9. record. Recording method: systolic blood pressure/diastolic blood pressure.
