Many people think that electronic sphygmomanometers are not accurate. This view is wrong. As long as the purchased electronic sphygmomanometer has passed the verification of international standards (check the manual carefully when purchasing), its accuracy can be trusted. If you are not at ease, you can compare it with a mercury sphygmomanometer after purchasing an electronic sphygmomanometer (it is recommended to go to a large hospital for comparison, because the mercury sphygmomanometer in a large public hospital requires standardized measurement and testing every year, so it is more reliable). It should be noted that currently only the arm-type electronic sphygmomanometer is recommended. The accuracy of the wrist-type sphygmomanometer for measuring blood pressure on the wrist has yet to be evaluated, so it is not recommended.
Compared with mercury sphygmomanometers, electronic sphygmomanometers require low measurement technology, are easy to use, and can avoid human errors. However, patients suffering from atrial fibrillation or frequent premature beats may have large errors in the measurement of electronic sphygmomanometers. In this case, it is best to measure several times, take the average value, or use a mercury sphygmomanometer to measure it.
With the development of science and technology, electronic sphygmomanometers have gradually replaced traditional sphygmomanometers, but many people have some doubts about electronic sphygmomanometers: Is it accurate or not? How to measure blood pressure? When is the best time to measure?
For sphygmomanometers, there are generally two types of electronic sphygmomanometers and medical mercury sphygmomanometers.
The measurement of medical mercury sphygmomanometer is more accurate, but it will be troublesome to operate, and it is difficult to use it alone.
The electronic sphygmomanometer is simple to operate, and the data is basically accurate. It is used to monitor the daily blood pressure of patients with hypertension and adjust the dose of antihypertensive drugs accordingly; remind patients to see a doctor at a time when blood pressure is high to avoid delays in their condition, etc. The electronic sphygmomanometer is fully competent.
But it should be noted that if you use an electronic sphygmomanometer, it is best to verify and calibrate it regularly.
In addition, the accuracy of the wrist sphygmomanometer may be worse due to the measurement position, blood vessel thickness, etc., so the arm-type electronic sphygmomanometer is still recommended.
The best time to measure blood pressure is within 1 hour after getting up in the morning, or before going to bed at night.
