With the relaxation of prevention and control policies, more and more people are paying attention to their own health, especially blood oxygen saturation. This is because after becoming a "little foreigner", various indicators of the body will change, the most important of which is the impact on the respiratory system, and respiratory conditions will also directly affect blood oxygen saturation.
Blood oxygen refers to the amount of oxygen contained in the blood. Generally speaking, the normal blood oxygen saturation of the human body is between 95% and 98%. Because the virus damages the respiratory system, the body's blood oxygen content will decrease and breathing difficulties may occur. People whose blood oxygen content is seriously lower than the normal value should go to the hospital for oxygen treatment in time.
In addition to oximeter , many smart watches can also test the blood oxygen content of the human body. However, not everyone has these devices. In order to obtain basic data, you can also use the following online blood oxygen and heart rate gadgets.

Testing Principle
According to the developer, the measurement principle relies on remote photoplethysmography (rPPG). Simply put, the camera captures the subtle periodic color changes on the face caused by breathing and heartbeat and converts them into corresponding physiological indicators. The developers of
also reminded that although this non-contact measurement method has certain rationality and accuracy, it is still far behind the professional oximeter, so the test data can only be used as a reference.
