This has a certain role, but his accuracy is relatively low, the doctor will not recognize these data, you have to go to the hospital, the hospital and the need to specialize in medical equipment for you to carry out another test.
From a technical point of view, such as ECG monitoring: the more patients you monitor, the larger the cumulative database, the more accurate your monitoring data will be, the more accurate the analysis of arrhythmia, which will bring the doctor a more meaningful reference value, why MOTORA ECG algorithms are highly regarded, is the reason. But the premise is that the production company has such a research and development department to do this kind of thing. Oxygen saturation monitoring and blood pressure monitoring general monitor can also monitor out, but it is difficult to say whether it is accurate or not. The monitor is the same as a watch, if it is not accurate, the use of meaningless, so that the ICU and operating room why willing to use imported monitors, because they are critical patients, inaccurate monitoring caused by errors in judgment will cause serious consequences, and even medical malpractice.
That is to say, that watch can measure the heart rate, the heart rate is the number of times the heart beats per minute.
