Q:Why is the blood pressure value deviated from the sphygmomanometer?

A:The deviation between the measurement value of the watch and the sphygmomanometer is determined by a variety of factors. The measurement site of the sphygmomanometer is in the radial artery, and the measurement site of the watch is the two main branches of the arteriole. Normaly, the aortic blood pressure measurement and the arteriole Blood pressure measurements will vary by three to forty; if you use a watch and a sphygmomanometer to measure at the same time, because the blood ?ows in the artery in the direction of the centrifuge, the sphygmomanometer measures the straps so that the lower part of your elbow is under pressure. Temporary blood cannot ?ow smoothly to the branch of the artery below, and the vascular tension is increased, which will make the upper and lower blood pressure measurement values more biased.
