How does the smart watch's blood oxygen monitoring save people?

Updated: Aug 18, 2021

Oxygen, the basis for the human body to survive

All cells in the human body depend on oxygen for their livelihoods, and blood oxygen content affects almost every part of the body. Low blood oxygen saturation can cause serious systemic complications, such as nervous system hypoxia, which can cause headaches, dizziness, irritability, mental disorders and even coma; cardiovascular hypoxia can cause myocardial ischemia, and severe cardiac arrest Stop, heart failure; hypoxia in the respiratory system can lead to respiratory failure and respiratory arrest.

In the domestic research reports on sudden exercise-related death, some cases indicate that the exerciser’s heart does not have qualitative lesions and abnormalities. The cause of death may be that the exercise load exceeds its tolerance, and the blood volume and oxygen demand required by the cardiac circulatory system suddenly increase. The supply has been relatively reduced. In this state of insufficient blood oxygen supply, the athlete's myocardium will experience acute ischemia, cardiac arrest and cerebral blood interruption, and then sudden exercise-induced cardiac death and brain death.

Why do some people have poor lung function and their blood oxygen saturation can still be normal?

The lung has five lobes, two on the left and three on the right. It can be said that the compensatory function of the lung is very strong and the lung function is not good. Will drop significantly. For example, patients with mild to moderate chronic obstructive pulmonary disease generally do not have the problem of decreased blood oxygen saturation, unless patients with severe chronic obstructive pulmonary disease have poor lung function and may experience decreased blood oxygen saturation in active or even resting states. Generally, the FEV1.0% of the lung function test is below 60%, and the oxygen saturation may be reduced. That is to say, blood oxygen saturation does not objectively reflect whether it is truly hypoxic, whether oxygen is needed or not. In mild hypoxia, oxygen saturation is basically normal.

In addition to the compensatory ability of the lung itself, there is another organ that plays a compensatory function to improve hypoxia, and that is the heart. Therefore, the heart rate will increase when breathing is difficult. The purpose is to pump more blood by increasing the number of heartbeats. To the peripheral tissue cells, increase the oxygen content in the blood. But the heart can't speed up endlessly, and heart failure or even failure will occur after a long time.

How to increase blood oxygen saturation?

If the blood oxygen level is too low, there will not be enough oxygen to be delivered to important tissues and organs. At this time, oxygen inhalation is the key treatment. Many COPD patients will noticeably improve their symptoms after inhaling oxygen, and the oxygen saturation will rise rapidly, but some are serious. The patient needs to use the ventilator in time to improve the symptoms of hypoxia. Of course, if the fundamental problem is to be solved, the primary disease must be treated at the same time.

How to perform blood oxygen monitoring quickly and conveniently?

Now the popular high-end smart watches on the market can basically quickly play a role in blood oxygen monitoring. Typical manufacturers include Apple, Huawei, Samsung, Xiaomi, Huami, and Veepoo. For example, Veepoo watch RIG has a built-in high-precision photoelectric sensor, 7 sets of light path design, 6 LED light sources, 3 electrodes with advanced blood oxygen monitoring algorithm, using green light, red light, infrared light, infrared LED to calculate the blood oxygen content. It also uses intuitive data to let the wearer know the status of the body's absorption of oxygen and the amount of oxygen delivered to the body.

VeePoo Watch RIG not only has the function of blood oxygen monitoring, but also other monitoring functions, such as blood pressure, heart rate, scientific sleep, etc., effectively helping the wearer to have a more comprehensive understanding of their overall health.
