Wearing a smart watch and using the real-time monitoring function of the smart watch, once the heart rate is abnormal, an early warning prompt will be given immediately, reminding the exerciser to adjust the exercise intensity in time to ensure exercise safety. In addition, healthy ordinary people can also wear wearable devices and use their blood oxygen monitoring to provide timely health warning services. So the principle of blood oxygen measurement of wearable devices on the market is similar, and what principle is used to achieve it. First of all, we need to understand the formation principle of blood oxygen. In fact, blood oxygen and heart rate, blood pressure, respiratory rate, and temperature are the five most critical health indicators of the human body. If you want to measure blood oxygen, you need professional equipment and large monitors in the hospital to monitor. At present, smart watches can obtain blood oxygen data through the wrist from the sensor hardware and algorithm, which is more portable than professional equipment in hospitals. , can achieve real-time close-to-body measurement.

Therefore, for ordinary people to keep the blood oxygen content at a normal level, one is to keep the air fresh and circulated, and the other is to strengthen the cardiopulmonary function exercise to enhance the breathing ability and blood transport ability. There is also the monitoring of sleep apnea syndrome. Smart watches can continuously monitor blood oxygen changes through built-in sensors in the device, and combine the existing heart rate sensor data to find potential apnea problems. Poor breathing during sleep can cause oxygen

The decreased intake will cause deep harm to the human body, such as inducing cardiovascular disease and increasing the risk of sudden death.

Patients with chronic diseases such as diabetes, heart disease and respiratory disease, especially the elderly, have the characteristics of low cure rate, low control rate, high complication rate, disability, and fatality rate. Good habits can slow down the development and deterioration of the disease, and daily monitoring of physical signs is particularly important. Like patients with chronic diseases, it is very necessary for sports enthusiasts to monitor their vital signs when exercising to adjust the intensity and frequency of exercise. Especially during high-intensity exercise, it is easy to have insufficient oxygen supply. In severe cases, it will lead to acute ischemia, cardiac arrest and interruption of cerebral blood in the athlete's myocardium, resulting in exercise-induced sudden cardiac death and sudden cerebral death. Exercise intensity is very important.

In addition to the conventional self-monitoring indicators such as heart rate, blood pressure, and body temperature. As more and more smart wearable devices have added the function of blood oxygen monitoring, blood oxygen monitoring has also become popular. For patients with chronic diseases, the monitoring of this indicator has also become easier. By recording these indicators, not only can you better monitor your health outside the hospital, but you can also go to the hospital for follow-up examinations in time according to the deterioration of the indicators. At the same time, the trend of these data changes is also a very important basis for doctors to diagnose and adjust treatment plans.

Smart watches are becoming more and more common, and wearing a smart watch to complete self-test is also a sense of responsibility for one's own health. Young people’s work and irregular work and rest can easily cause some bad results to the body. When wearing a smart watch, you can pay attention to the changes in your body, control your daily work and rest, and strengthen exercise to improve your immunity. These are all beneficial.
