The blood oxygen saturation value is one of the indicators for the detection of new corona virus pneumonia. It is self-tested at home at any time, bringing peace of mind to the family. Blood oxygen saturation is between 95% and 100%, which is normal; between 90% and 95%, it is mild hypoxia; below 90%, it is severe hypoxia, which needs to be sent to hospital for treatment as soon as possible.
Normal human arterial blood has a blood oxygen saturation of 98% and venous blood is 75%. It is generally considered that the normal saturation should be no less than 94%, and below 94% is insufficient oxygen supply.
