Basic Principles and Interpretation of Viatom Reusable SpO₂ Sensors
The blood oxygen monitoring module consists of three parts: optical sensor, front-end signal acquisition system and algorithm. The principle is that according to the different absorption rates of red light and infrared light by oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) in the blood, the red light and infrared light are irradiated to the skin through an optical sensor, and then the subcutaneous blood vessels are obtained. After the reflected red light and infrared light, the blood oxygen is finally calculated by the algorithm.
