Definition of SpO2 Sensor Blood Oxygen Probe

SpO2 probes also called SpO2 probes, which means that the fingertips or clips of the probe are fixed to the fingertips, and the fingers are used as transparent containers for hemoglobin. Red light with a wavelength of 660 nm and near-infrared light with a wavelength of 940 nm were used as incident light sources, and the intensity of light transmission through the tissue was measured to calculate the hemoglobin concentration and blood oxygen saturation. Through SPO2 monitoring, you can get SPO2, pulse rate, and pulse wave. Used for blood oxygen monitoring of various patients, usually the other end is connected to the ECG monitor.
