1. The room should be quiet, and the room temperature should be kept at about 20℃.

2. Before the measurement, the client should be mentally relaxed, it is best to rest for 20 to 30 minutes, empty the bladder, do not drink alcohol, coffee and strong tea, and stop smoking.



3. The subject can be seated or supine. The tested arm should be placed at the same level as the right atrium (the arm should be at the same level as the fourth costal cartilage when sitting, and at the same level as the midaxillary line when lying), and the abduction should be 45 degrees. Roll up your sleeve to your armpit or remove one side of your sleeve for easier measurement.



4. Before measuring blood pressure, the gas in the cuff of the blood pressure monitor should be drained first, and then the cuff should be tied to the upper arm smoothly, not too loose or too tight, so as not to affect the accuracy of the measurement value. The humeral pulse of the middle of the air bag to the elbow socket (most electronic sphygmomanometers have this position marked with an arrow on the cuff), and the lower edge of the cuff is 2 to 3 cm away from the elbow socket.



5. Turn on the electronic blood pressure monitor and record the blood pressure measurement results after the measurement is completed.



6. After the completion of the first measurement, it should be completely deflated, wait at least 1 minute, and then repeat the measurement once, taking the average value of the two times as the obtained blood pressure value. In addition, if you want to determine whether you suffer from high blood pressure, it is best to measure at different times, it is generally believed that there are at least 3 different times of blood pressure measurement values, can be defined as high blood pressure.



7. If you need to observe blood pressure changes every day, you should measure the blood pressure on the same arm with the same sphygmomanometer at the same time, using the same position, so that the measured results are more reliable.
