spo2 sensor working principle, function and structure

this Spo2 sensor is mainly through the light emitting diodes issued by the red and infrared light transmission of blood, by the photoelectric detection device to detect the degree of light absorption of blood and its signal transmission to multi-parameter patient monitor, pulse oximeter and other ancillary equipment on the signal Of the amplification, simulation and display of human physiological data, the hospital for patients with noninvasive continuous measurement of patients with arterial or venous blood oxygen content and blood oxygen percentage percentage value for the medical staff to provide patients with physiological information
