How to measure blood oxygen with smartwatch?

Blood oxygen can be a crucial health indicator and monitoring it from time to time can help you take better care of yourself. With the advent of smartwatches, especially the Bluetooth Smart Sport Watch, monitoring your blood oxygen levels has become more convenient. So how to measure blood oxygen levels using your smartwatch?


Before we get into the details, it is important to understand why we need to monitor blood oxygen? Blood oxygen saturation is an important indicator to measure the oxygen-carrying capacity of blood, and it is also an important parameter reflecting lung function and circulatory function. Blood oxygen saturation, blood pressure, respiration, body temperature, and pulse are regarded as the five basic signs of life, and they are important pillars for maintaining normal life activities. The decrease in blood oxygen saturation will cause a series of hazards to the health of the body.


The first step to measuring your blood oxygen levels is to ensure whether your smartwatch has the sensor. There is a sensor on the back of the XW100 smart blood oxygen monitor watch to monitor blood oxygen. Afterwards, wear the smart watch directly and put it close to your skin.

To get started with the measurement process, swipe the watch screen and select the blood oxygen function from the menu. Then the system will prompt you: Wear it too tight, and keep the screen facing up. Once you tap start, it will measure your blood oxygen saturation and provide you with a SpO2 level reading and heart rate data within seconds.


You can also use a healthy monitor app that is compatible with XW100 smartwatch, such as x-fitness. This app will enable you to get accurate readings of your SpO2 levels. When using a healthy monitor app, you will also need to ensure that your smartwatch is either connected to your smartphone via Bluetooth.

One important thing to note when measuring your blood oxygen levels is that the readings can be affected by different factors such as activity level, altitude, and medical conditions. Therefore, it is essential to measure your blood oxygen levels when you are at rest and under normal conditions.


In conclusion, measuring your blood oxygen levels with your smartwatch has become more accessible, thanks to the SpO2 sensors located on the back of the device. Of course, there are many devices that can be used to measure blood oxygen, such as fingertip blood oxygen monitoring, smart bracelets, etc.

However, it is important to remember that blood oxygen levels should only be used as a general indicator of health and should not be substituted for medical diagnosis or treatment. Once you find your oxygen saturation suddenly low or feel unwell, you need to pay enough attention and seek medical attention in time.
