What is an electronic sphygmomanometer

The principle of electronic sphygmomanometer adopts oscillometric method, which is accurate in principle. The clinical verification of electronic sphygmomanometer is designed with auscultation as the standard and statistical method. But this does not mean that the auscultation method using mercury pressure gauge is more accurate than the electronic sphygmomanometer. Of course, it is not necessarily correct to think that the measurement results of electronic sphygmomanometer are more accurate than those measured by auscultation with mercury pressure gauge.

Because mercury is too destructive to the environment, it is recommended not to use mercury sphygmomanometer. The state also prohibits the use of mercury sphygmomanometer by legislation. The mercury sphygmomanometer used by doctors in hospitals is only a tool for pressure measurement. It is one-sided to think that mercury sphygmomanometer is an accurate sphygmomanometer, because mercury sphygmomanometer is just a manometer, and the focus is on the auscultation performed by doctors through stethoscopes. It is generally forbidden to use mercury sphygmomanometer in developed countries in the world, but pressure gauges are used. However, due to the mechanical design principle of pressure gauges, they must be calibrated once every three months. Now the electronic sphygmomanometer has realized automatic intelligent measurement, and the measured data can be automatically transmitted to the health management platform through the network, and the generated health data report will be fed back to users. The measurement results are more accurate than the traditional electronic sphygmomanometer because of the more advanced technology. It is normal for individual subjects to have differences between electronic sphygmomanometer and auscultation.
