Breath In With Veepoo's RIG Smartwatch


Smartwatch Oxygen Saturation

If you are new to the Smart wearable world, it must be overwhelming to see all these functions on your device. In this article, we will introduce an important health related feature, which is the oxygen saturation level and how could we utilize this particular information on your smartwatch. Humans live on oxygen. After oxygen is inhaled from the lungs, the oxygen enters the blood through the capillaries, and is transported by the blood to various organs or cells in the body for use. The higher the oxygen content in the blood, the better the human metabolism.However, high blood oxygen content is not always a good phenomenon. The blood oxygen in the human body has a certain degree of saturation. If it is too low there's insufficient oxygen supply in the body, and high saturation could lead to aging of cells in the body. In General, The human body's normal blood oxygen saturation is above 95%.




Smartwatch Oxygen Saturation


Under normal circumstances, most people's measurement is around 96%-100%. When it is less than 90%, it is usually related to serious problem with cardiopulmonary function. If it reaches the level below 80%, the average person has lost consciousness and can't take the blood oxygen test by himself awake. Therefore, it is also very important to pay attention to blood oxygen saturation. The sooner the problem is discovered, the sooner the correct treatment can be made. That's where a smartwatch can help because it will allow you to record oxygen saturation of yourself anytime,anywhere, but for better accuracy you should get a reliable health smartwatch such as Veepoo's RIG.



  • In our daily life, there are several scenarios that may require the detection of blood oxygen saturation by a smartwatch:


When engaged in outdoor sports such as hiking. We know that the higher the altitude, the thinner the air, and the lower the human blood oxygen saturation. When you are engaged in outdoor activities in high-altitude areas, Smartwatch can assess your physical condition in real time, thereby adjusting the current exercise according to the report by the smartwatch to cope with the changing environment.


Perform high-intensity mental work. Remember to check your oxygen saturation level at work. The oxygen consumption of the brain accounts for 20% of the whole body oxygen uptake. When high-intensity mental work is performed, the oxygen consumption of the brain will inevitably increase. The human body can take in limited oxygen, consumes too much, and consumes less, which will not only cause dizziness, fatigue, slow response and other problems, but also cause damage to the brain. People who study or work for a long time every day need to pay attention to their blood oxygen saturation.


Drinking. The human body needs three units of oxygen for every unit of alcohol to completely decompose. Therefore, hypoxia is one of the important manifestations of drunkenness. However, long-term alcoholics have developed a certain tolerance to alcohol and hypoxia, and they are basically unable to detect them when they are slightly drunk. Such people need to pay more attention to monitoring changes in blood oxygen when drinking.


  • What technology does smart wearable device use to detect blood oxygen saturation?


The oxygen level of hemoglobin in the blood will affect the blood's absorption of red light and infrared light. Specifically, hemoglobin saturated with oxygen absorbs more infrared light, and hemoglobin without oxygen absorbs more red light.

Smart wearable devices such as smart bracelets or watches use photoelectric sensors to perform optical measurement based on the principle that the amount of light absorbed by arterial blood varies with arterial pulsation. Luminous tubes are installed in the smartwatch to emit red light and infrared light respectively, and a photodetector is installed to convert the red light and infrared light detected through the arteries into electrical signals to obtain a set of data. Based on these data and using background algorithms, the sports watch can calculate the estimated value of the user's blood oxygen saturation.
