step S1: and measuring data of the blood oxygen saturation of the person to be measured is obtained through the photoelectric pulse oximeter.
Specifically, the basic principle of the electro-optical pulse oximeter is the lambert-beer law, which uses the absorption difference of oxygenated hemoglobin and non-oxygenated hemoglobin for different wavelengths of light. The amount of light absorbed during these pulsations is related to the oxygen content in the blood. The microprocessor calculates the ratio of the two spectra absorbed and compares the result with a table of saturation values stored in a memory, thereby obtaining the blood oxygen saturation.
A typical oximeter sensor has a pair of LEDs that face a photodiode through a translucent portion of the patient's body, typically the fingertip or earlobe. One of the LEDs is red, with a wavelength of 660 nm; the other is infrared, and the wavelength is 940 nm. The percentage of blood oxygen is calculated by measuring the two wavelengths of light having different absorbencies after they have passed through the body.
Step S2: and acquiring skin color information of the person to be detected, and selecting a calibration curve according to the skin color information. Specifically, the standard measurement curve is calibrated by using the measurement result of the standard blood gas analyzer as a reference to obtain a plurality of different measurement curves, and after the skin color information of the person to be measured is obtained, the calibration curve is selected according to the skin color, so that the result can be conveniently calibrated according to the calibration curve.
Step S3: and substituting the measurement data into the calibration curve to obtain the arterial blood oxygen saturation measurement result of the person to be measured. Specifically, the measurement result with higher accuracy is obtained by substituting the measurement data into the calibration curve and calibrating the calibration curve.

Specifically, carry out real-time supervision to measurement personnel through photoelectricity pulse oximeter, carry out oximetry through blood gas analyzer extraction measurer's arterial blood, both go on at the same time, because blood gas analyzer's measuring result is comparatively accurate, can mark as the standard to photoelectricity pulse oximeter's monitoring data.
Step S212: the oximetry data is classified according to different skin tone types. Specifically, skin color has a large influence on the measurement result, so that the blood oxygen measurement data is classified according to the skin color type, and the calibration curves of different skin color types can be generated conveniently in the follow-up process.
Step S213: and calibrating the blood oxygen monitoring data according to the classified blood oxygen measurement data, and generating a plurality of calibration curves according to the calibration result. Specifically, the blood gas and the pulse blood oxygen recording value in the blood oxygen monitoring data are compared and analyzed according to the classified blood oxygen measurement data, and the measurement curves with different skin colors are obtained by calibrating on the basis of a standard curve through a mathematical method. Compared with a general standard measurement curve in the photoelectric pulse oximeter, the calibration curve has smaller error when monitoring the blood oxygen values of different skin color crowds.
