Electronic sphygmomanometer is a medical instrument that uses modern electronic technology and indirect blood pressure measurement principle to measure blood pressure. Electronic sphygmomanometer can be divided into arm type and wrist type; Its technology has experienced the most primitive development of the first generation, the second generation (arm use) and the third generation (wrist use). Electronic sphygmomanometer has become the main tool for home self-testing blood pressure. Electronic sphygmomanometers are also increasingly used in hospitals and other medical institutions.
Applicable people:
For the commonly used electronic [1] sphygmomanometer (including the commonly used medical mercury sphygmomanometer), there is a certain error in indirectly measuring blood pressure compared with the direct measurement method, and the error is usually between 5% and 20%.
Indirect measurement is not suitable for people with low or high blood pressure, especially patients with massive hemorrhage, whose blood pressure is seriously low. Indirect measurement may cause more than 40% error, leading to doctors making wrong judgments.
In addition, wrist electronic sphygmomanometer is not suitable for the elderly, because their blood pressure is already very high and blood viscosity is also very high. Compared with the blood pressure pumped by the heart itself, the result measured by this sphygmomanometer has been much lower, and this measurement result has no reference value.
Finger-cuff sphygmomanometer was developed in Japan in the early years, and it was not long before it was proved to be unworkable. Therefore, finger cuff sphygmomanometer is not suitable for any crowd!
To sum up, the electronic sphygmomanometer is mainly suitable for people with hypertension below grade 3, mainly used for daily blood pressure monitoring. classify
