The traditional method of measuring oxygen saturation is to be human blood , blood gas analyzer re-use electrochemical analysis , measuring blood oxygen partial pressure PO2 calculate the oxygen saturation. This method is cumbersome and can not be continuously monitored
Using a fingertip photoelectric sensor , measurement , simply set the sensor on a human finger , a finger as a transparent container containing hemoglobin using red and near -infrared wavelength of 660 nm, 940 nm of the incident light as a light source , measured by the intensity of the light conducting tissue bed to calculate the concentration of hemoglobin and oxygen saturation, the instrument can show the body oxygen saturation , for clinical provides a continuous non-invasive blood oxygen measuring instruments
Generally considered normal SpO2 should not be less than 94% , 94 % or less of oxygen deficiency
Generally considered normal SpO2 should not be less than 94% , 94 % or less of oxygen deficiency
Hypoxic hazards
Hypoxia has a huge impact on the body . For example, the impact on the CNS, liver and kidney function
Hypoxia and homeostasis in patients with the disease itself may have a significant impact on the environment within the patient
