The inaccuracy of electronic sphygmomanometer is not due to the inaccuracy of pressure sensor, but the error of domestic pressure sensor can be controlled at 1mmHg, because the measurement principle of oscillometric method is flawed.
Sphygmomanometer mainly includes auscultation sphygmomanometer and oscillometric sphygmomanometer.
Auscultation includes manual auscultation and automatic auscultation. Mercury sphygmomanometer (manometer) and spring sphygmomanometer (manometer) are early manual auscultation sphygmomanometer, and now there are digital display sphygmomanometer, light display sphygmomanometer and liquid crystal sphygmomanometer. Auscultation automation technology is difficult. The automation of Coriolis auscultation will be the main direction of sphygmomanometer development. Automatic auscultation sphygmomanometer will make blood pressure measurement more convenient and accurate.
Oscillographic method, also known as oscillation method, is simply to obtain the oscillation wave generated during deflation and convert it into blood pressure value through a certain algorithm. Most electronic sphygmomanometers are designed according to the oscillometric principle. Electronic sphygmomanometer can be divided into upper arm, wrist and finger. Please choose auscultation automatic sphygmomanometer when choosing sphygmomanometer. Accurate measurement of blood pressure is the premise of preventing and treating hypertension.
Question 2: the brand of bracelet seems to be very accurate in measuring blood pressure, and even the steps are not very accurate. And FITBIT is too expensive, don't consider it? Lexin's medical treatment seems to be quite accurate, but after all, it is a medical bracelet and the price is not low. If the price is close to the people, the cost performance is relatively high. I suggest that both LeTV and Bolun can consider it.
Question 3: What brand of bracelet is 1 for monitoring blood pressure and heart rate? At present, most smart bracelets on the market monitor the resting heart rate, which refers to the number of heartbeats per minute when awake, inactive and quiet. 2. The importance of heart rate is beyond doubt, so if the current smart bracelet does not have the function of heart rate monitoring, it can basically be ignored. Of course, the heart rate value monitored by the general smart bracelet can be used as a reference. You can also go to the hospital for monitoring if necessary. 3. I recently started a smart bracelet of hesvit, one of which is heart rate monitoring. Personally, I think it is still of great reference value. I talked to a doctor last time.
Question 4: Can the current smart bracelet measure blood pressure? Nowadays, bracelets generally have the functions of exercise step counting, sleep monitoring and heart rate detection, but there is no bracelet that can measure blood pressure. You can buy a smart sphygmomanometer for your elders directly.
Question 5: How to measure data with a bracelet that can measure blood pressure and heart rate? How accurate is it? The cloud embedded health+ECG breathing bracelet conducts current through the human body through two chips at the bottom of the bracelet and flows back to the other hand. The other finger is placed on the chip above the bracelet to form a circle, and the data can be measured. All of them are accurate, the accuracy rate is 99%, and the functions are complete, such as heart rate measurement, breathing training and so on.
Question 6: Can the Midong Health Bracelet measure blood pressure? Sorry, the Midong Health Bracelet does not support blood pressure measurement. You can know your health by measuring heart rate, heart rate variability and cardiovascular health index.
Question 7: Is the bracelet that can detect blood pressure accurate? Y.M.H Yamaha sphygmomanometer adopts imported chips and broadcasts in one-button intelligent language.

Question 8: Is there a bracelet or smart watch that can measure blood pressure? There seems to be, but it is immature and inaccurate. It's all liars' stuff. It is recommended not to buy it.
Question 9: Can the smart bracelet measure blood pressure? 10 smart bracelet can effectively record daily exercise. Sleep situation. It's safer to answer the phone while driving.
