how to use

1) Keep quiet indoors, and the room temperature should be kept at about *0 ℃.



2) Before the measurement, the examinee should relax, have a rest of ****0 minutes, empty the bladder, do not drink alcohol, coffee and strong tea, and stop smoking.



3) The subject can take a sitting position or a supine position. The arm of the subject 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 the arm should be placed at the level of the axillary midline when lying), and abducted *5 degrees. Roll up the sleeve to the armpit, or take off one sleeve for measurement.



4) Before blood pressure measurement, the gas in the sphygmomanometer cuff should be evacuated first, and then the cuff should be tied to the upper arm flatly without being too loose or too tight, so as not to affect the accuracy of the measured value. The middle of the air bag is opposite to the brachial artery of the cubital fossa (most electronic sphygmomanometers mark this position with arrows on the cuff), and the lower edge of the cuff is **3 cm from the cubital fossa.



5) Open the electronic sphygmomanometer and record the blood pressure measurement results after the measurement.
