You can use the "Blood Oxygen" App to measure the blood oxygen level directly on your wrist as needed to understand your overall health. The data measured by the "Blood Oxygen" App is not suitable for medical use and can only be used for general fitness and health purposes. The "Blood Oxygen" App can only be used in some countries and regions.
Blood oxygen monitoring on mobile phones is only an auxiliary indicator. If you are really unwell, you should go to the hospital in time. We can't blindly believe in blood oxygen monitoring. After all, such products do not detect the body deeply and are not necessarily accurate.
