For the commonly used electronic sphygmomanometers (including the commonly used medical mercury sphygmomanometers), the indirect method is used to measure blood pressure. Compared with the direct method, there is a certain error, and the error is usually between 5% and 20%.
Indirect measurement method is not suitable for people with low or high blood pressure, especially for patients with massive hemorrhage, whose blood pressure is seriously low. Indirect measurement method may cause more than 40% error and lead to doctors' wrong judgment.
In addition, wrist electronic sphygmomanometer, because of its convenient use, has been widely used. Especially in the cold winter, the use of arm type electronic sphygmomanometer is not very convenient.
Due to the successful development of the fourth generation of electronic sphygmomanometer technology, wearable watch sphygmomanometer (blood pressure watch) will enable the detection of blood pressure anytime, anywhere.
The finger cuff sphygmomanometer, which was developed in Japan in the early years, soon proved to be impractical. Therefore, finger cuff sphygmomanometer is not suitable for any crowd!
In conclusion, electronic sphygmomanometer for daily blood pressure monitoring will be further popularized.
