There are many sphygmomanometer medical terminology. Today, we briefly introduce the relevant knowledge of electronic sphygmomanometers.
The principle of the electronic sphygmomanometer adopts the oscillometric method, which is accurate in principle. The clinical verification of the electronic sphygmomanometer is designed with auscultation as the standard and using statistical methods. But this does not mean that the results measured by auscultation with mercury pressure gauges are more accurate than electronic sphygmomanometers. Of course, it is not necessarily correct to think that the measurement result of an electronic sphygmomanometer is more accurate than the result of auscultation using a mercury pressure gauge.
Because mercury is too destructive to the environment, it is recommended not to use a mercury sphygmomanometer. The country also bans the use of mercury sphygmomanometers in legislation. The mercury sphygmomanometer used by hospital doctors is just a tool for pressure measurement. The point that the mercury sphygmomanometer is an accurate sphygmomanometer is unilateral, because the mercury sphygmomanometer is just a pressure gauge, and the focus is on auscultating the doctor through the stethoscope. Developed countries in the world usually prohibit the use of mercury sphygmomanometers, but pressure gauges should be used, but due to the mechanical design principle of pressure gauges, calibration must be carried out every three months.
Nowadays, the electronic blood pressure monitor has realized automatic and intelligent measurement. The measurement data can be automatically transmitted to the health management platform through the network, and the health data report will be generated and fed back to the user. Due to the use of more advanced technology, the measurement results are more accurate than traditional electronic sphygmomanometers. For individual subjects, it is normal for differences between electronic sphygmomanometers and auscultation methods.
Well, here is the current knowledge about electronic sphygmomanometers. Next time I will continue to discuss the principle of the sphygmomanometer.
