Saturation oxygen is an important biological indicator for the respiratory and circulatory of the human being. Many clinical disease can result in insufficient oxygen supply, which will directly affect the normal metabolism of cells, a serious threat to health, so the real-time monitoring of arterial oxygen concentration is very important in the clinical application. This paper introduced to the use of STM8L ultra-low-power microcontroller as the main chip, and using a fingertip photoelectric sensor, in the red wavelength of 660nm and 940nm infrared light as the probe light source, and use the appropriate signal amplifier, those provides a quick means of direct actions for clinical blood oxygen saturation measured by non-invasive method. The method uses a transmissive principle to monitor the pulse beat and the signal amplitude, and calculates the blood oxygen saturation parameter. The results of experiment show that the system as a whole is low-power consumption, stable performance, accurate measurement.
