The deviation between the measurement values of the watch and the

sphygmomanometer is determined by many factors. The measurement part of the sphygmomanometer is in the brachial artery, and the measurement part of

the watch is in the two main public branches of the micro artery.Under normal circumstances, the measurement value of aortic blood pressure and micro arterial blood pressure will differ by 30 to 40. lf you use a watch and a

sphygmomanometer to measure at the same time, since the blood flowing in the artery is in the centrifugal direction, when the sphygmomanometer measures, the lower part of your elbow is under pressure, and the blood

cannot branch smoothly to the artery below. Flow, increased vascular tension, will make the upper and lower blood pressure measurements more deviations.

The ambient temperature during bathing is relatively high, which will produce a lot of water vapor, and the water vapor is gaseous, its molecular radius is small, and it is easy to seep into the gap of the watch. When the temperature drops, it will condense into liquid water droplets again, which is easy to cause The internal circuit of the watch is short-circuited, destroying the circuit board, and then destroying the watch.
