Wearable technology With the development of the market day by day, smart watches that increase the user experience and become highly skilled especially in health began to emerge. As of today, one of the most prominent features of these devices, which we frequently encounter with the news that they save human lives, is one of the most prominent features. SpO2 is the measurement. Alright SpO2 what is it and how do smartwatches measure it?
What is SpO2?
SpO2, the level of oxygen in the blood, represents the percentage of oxygen carried by red blood cells from the lungs to the rest of the body. Learning how effectively the blood in the body can perform this vital task can help to understand overall health.
in the blood of many oxygen level is in the range of 95-100 percent. However, there are also people who continue their lives normally even though their blood oxygen level is below 95 percent. More measurements taken while sleeping low readings are quite normal and therefore some users may have oxygen values below 95 percent.

How do smartwatches measure SpO2?
As mentioned above, nowadays in the premium segment Most of the smartwatches in the market include this feature. So how do these devices measure the oxygen level (SpO2) in the blood?
smart watches, red And Reflection oximetry that reflects infrared light (IR) to the wrist technique uses. This red light enters the oxygen-containing blood tissues and absorbs the light. to the sensor reflects back. The difference between the level of injected light and the level of reflected light is shown as the human body’s SpO2 level.
Of course, the measurements made by these devices their accuracy is also discussed. First of all, we should point out that the measurements made by a medical device such as an oximeter are more is reliable. These devices are often 650nm and have wavelengths of 950nm red and infrared LEDThey measure with.
The wavelengths in smart watches are not that advanced.
These devices measure through their sensors. oxygen level in the blood (SpO2) Although the accuracy of health data such as do not treat it as a precise dataI we recommend. For precise and more accurate results, it would be healthier to choose medical devices produced for such purposes.
