1. It may be caused by the strong measurement sensitivity of the bracelet. The sensitivity of the bracelet itself is relatively strong, which may cause the measured blood oxygen value to be high and low.
2. There may be some errors in the size of the bracelet. If improperly worn, it may lead to errors in blood oxygen measurement.
If you want to accurately measure oxygen saturation, you can follow the following steps:
1. Make sure that the Huawei watch and Huawei mobile phone are connected normally, and the Bluetooth of the watch has been paired successfully.
2. Ensure that Huawei watches and Huawei mobile phones are in a non-sleep state, and the watches have entered a state of motion.
3. In Huawei Health App, go to the watch details page and check the blood oxygen data measured in the "Blood Oxygen Saturation" card.
4. If the measurement is not accurate, you can try to adjust the position of the watch, or wait until the measurement result is stable before measuring.
If the above methods can't solve the problem, it is recommended to contact customer service or go to the relevant after-sales service center for consultation and maintenance.
