Description

technical field

[0001] The invention relates to the research field of a vital sign parameter detection device, in particular to a blood oxygen saturation detection device based on a wearable device. Background technique

[0002] Oxygen in the air enters the blood after being exchanged in the lungs of the human body, and is combined with hemoglobin to supply to the whole body to maintain the normal metabolism of cells. Blood oxygen saturation (SpO2) is used to reflect the oxygen level in the blood, and blood oxygen saturation refers to the percentage of the capacity of oxygenated hemoglobin (HbO2) in the blood to the total hemoglobin (Hb) capacity. Under normal circumstances, the blood oxygen saturation of the human body is maintained at 98%, generally not lower than 94%. If the blood oxygen saturation is too low, it indicates that the tissues cannot get enough oxygen, or cannot make full use of oxygen, causing tissue Abnormal changes in the metabolism, function, and even mo...
