Application skills of sphygmomanometer
Mercury sphygmomanometer:
1. Before measuring blood pressure, keep the patient in bed for a few minutes. Expose the right arm, always expose the shoulder, and straighten the elbow, palm up flat.
2. Place the sphygmomanometer on the bed or table so that the '0' point of the sphygmomanometer is on the same plane as the patient's heart.
3. Wrap the cuff of the sphygmomanometer around the patient's upper arm. The lower edge of the cuff should be 2-3cm away from the elbow socket, not too tight or too loose.
4. Close the balloon and inflate the cuff until the brachial artery pulsation is not audible. Then slowly release the valve to reduce the pressure. Pay attention to the scale of the mercury column until the first pulsation is heard. At this point, the scale of the mercury column is the systolic pressure.
5. The pressure continues to decrease until the pulsating sound of the artery increases gradually until it suddenly softens and weakens. At this time, the scale is diastolic blood pressure (note that the pulsating sound does not disappear completely). Blood pressure should be measured continuously for two or three times, and the lowest value should be taken.
Electronic sphygmomanometer:
1. Before measuring blood pressure, keep the patient in bed for a few minutes. Expose the right arm, always expose the shoulder, and straighten the elbow, palm up flat.
2. Place the sphygmomanometer on the bed or table so that the '0' point of the sphygmomanometer is on the same plane as the patient's heart.
3. Wrap the cuff of the sphygmomanometer around the patient's upper arm. Long press the switch of the electronic sphygmomanometer, the sphygmomanometer will start to measure, wait for the determination of the measured value of the sphygmomanometer, and do not move during the measurement. After the measurement, press the switch button to turn off the sphygmomanometer. It is better to measure twice, and then repeat the above steps.
If possible, record the measured values of each field for easy observation.
