Is the mercury sphygmomanometer more accurate than the electronic sphygmomanometer? The following editor will answer one or two for you.
The principle of the electronic sphygmomanometer adopts the oscillometric method, which should be accurate in principle. The clinical verification is designed with auscultation as the standard and using statistical methods. But this does not mean that the results measured by the auscultation method using a mercury pressure gauge are more accurate than those of an electronic sphygmomanometer. Of course, it is also wrong to think that the measurement result of the electronic sphygmomanometer is more accurate than the result measured by the auscultation method using a mercury pressure gauge.
The mercury column sphygmomanometer used by doctors in the hospital is just a tool for pressure measurement. The view that the mercury sphygmomanometer is an accurate sphygmomanometer is one-sided, because the mercury sphygmomanometer is just a pressure gauge, and the emphasis is on the doctor’s auscultation through a stethoscope. Developed countries in the world generally ban the use of mercury-type sphygmomanometers and adopt pressure gauges. However, due to the mechanical design principle of pressure gauges, it must be calibrated once every three months.
Nowadays, electronic sphygmomanometers have 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. The measurement results are more accurate than traditional electronic blood pressure monitors due to the use of more advanced technology. The following editor will recommend several accurate and easy-to-use electronic sphygmomanometers:
