What is the blood oxygen saturation measurement on the Xiaomi Smart Band 9 Active?
Blood oxygen saturation measurement (also known as SpO₂ measurement) on the Xiaomi Smart Band 9 Active refers to the process of measuring the percentage of oxygen in your blood, which is an important indicator of your respiratory and overall health.
Here's what happens during the measurement process:
1. The Xiaomi Smart Band 9 Active uses optical sensors to measure blood oxygen saturation. The process takes around 15-60 seconds to complete, depending on factors such as how snugly the band fits on your wrist, your skin characteristics, and the surrounding environment. If any of these factors cause an issue (e.g., improper fit or environmental interference), the measurement will time out;
2. During the measurement, the band activates red and infrared lights (the infrared light is invisible to the naked eye), which penetrate the skin to measure the oxygen levels in the blood. If the indicator flashes in green, it means that it is measuring the heart rate;
3. To ensure an accurate blood oxygen measurement, it's essential to wear the band properly. Adjust the band so that the back of the device is snug against your wrist, ensuring good skin contact. This minimizes the potential for interference during the measurement and improves the accuracy of the results.
