if doctor want to know the spo2 level, first need have the patient monitor and together with the spo2 sensor, put the patient finger into the adult finger clip spo2 sensor.
Multi-clinical disease will cause the lack of oxygen supply, which will directly affect the normal metabolism of cells, serious also threaten human life, so the real-time patient monitor of arterial oxygen concentration in clinical care is very important.
Traditional blood oxygen saturation measurement method is the first blood collection, and then use the blood gas analyzer for electrochemical analysis, measured oxygen partial pressure PO2 calculated oxygen saturation. This method is cumbersome and can not be continuously monitored.
With the finger clip spo2 sensor, the spo2 sensor is set on the human finger, and the finger is used as the transparent container containing hemoglobin. The red light of 660 nm and the near infrared light of 940 nm are used as the injection light source. Tissue bed light intensity, to calculate the hemoglobin concentration and oxygen saturation, the instrument can show the human blood oxygen saturation, for the clinical provision of a continuous undamaged blood oxygen measuring instruments
