1. Choose a mercury sphygmomanometer or an electronic sphygmomanometer?
A professional doctors, of course, can choose mercury sphygmomanometer, because the mercury sphygmomanometer measurement accuracy and stability is higher, the user's technical requirements are higher. If the technique is not in place and the operation is not proper, it is easy to make an error in the measured blood pressure.
B ordinary people, choose an electronic blood pressure monitor. The electronic sphygmomanometer is easy to use and easy to measure.
2. Does the electronic sphygmomanometer choose arm or wrist?

The memory function of the sphygmomanometer is to store the blood pressure record (high voltage, low pressure, pulse, etc.) of the measured person in the machine, so that the measured person who uses it for a long time knows the blood pressure value of himself for a period of time, which is a Not a nice feature. Memory functions are generally divided into: single-group memory and multiple-group memory functions; with date and time function and without date and time function.
