On the details page of Huawei Health's application equipment, click Health Monitoring to turn on the automatic blood oxygen detection switch. When it is judged that you are at rest, the device will automatically measure and record the oxygen saturation. Click low blood oxygen reminder to set a reminder when the blood oxygen saturation is lower than the lower limit in non-sleep state.
The blood oxygen saturation measurement of the bracelet is accurate because it is measured according to our pulse, and the result is close to our body. As long as we exercise vigorously, the measured values are accurate.
