Xiaomi bracelet 82 what does it mean

Blood oxygen. The normal range of blood oxygen measured by the millet bracelet is 95%-100%, and blood oxygen saturation below 95% means that there are certain problems in the body, such as COPD, heart disease, anemia, respiratory-related diseases, etc. Blood oxygen values below 94% should be taken to the hospital or clinic as soon as possible to receive professional examination and treatment, so as to avoid causing more damage to the body, where the blood oxygen value of 82% is on the low side, requiring further attention and treatment. As a smart wearable device, the Xiaomi bracelet has some errors in its measurement of blood oxygen, and cannot replace professional medical equipment and diagnosis by professional doctors.
