Many people with relevant backgrounds know that accurate measurement of blood pressure depends on arterial catheterization, but this tool is not affordable for all people, and there are many limitations, so it is only used in cardiac catheterization. The other two commonly used are electronic sphygmomanometer and mercury sphygmomanometer, although these two tools can only get as close to the real blood pressure data as possible, but they can also play a good reference value.
The first is that Mantissa preference can be reduced or eliminated.
Mercury sphygmomanometers like to habitually record blood pressure readings as the last 0 or 5 mmHg. And in the actual operation of the doctor, it is found that the incidence of this Mantissa preference is not low, which will easily lead to the doctor to make a wrong judgment. However, if you use an electronic sphygmomanometer, you can well reduce and eliminate Mantissa preference.
The second is that multi-parts can be measured synchronously.
This function means that the electronic sphygmomanometer can effectively evaluate the difference in blood pressure between the arms and limbs. This method of measurement can reduce man-made errors and eliminate the differences caused by blood pressure fluctuations at different times and different mental states.
The third is to do self-help blood pressure measurement.
This is also an advantage of the improved oscillographic electronic sphygmomanometer, which can work on its own, leave patients alone in the consultation room, and measure automatically without the presence of medical personnel.
The fourth is to have the function of memory.
The auxiliary starting device of the electronic sphygmomanometer includes the memory function, but the ambulatory blood pressure measurement is realized.
Above we have analyzed why the electronic sphygmomanometer is more popular, it is very easy to operate. Therefore, when we choose mercury sphygmomanometer and electronic sphygmomanometer, we can consider more electronic sphygmomanometer.
