In order to alleviate patients pain for the long time using transmission type non-invasive pulse and blood oxygen saturation monitor, a pulse and blood oxygen saturation monitoring method is proposed by using the reflection type photoelectric sensor. Using LabVIEW software with strong function of data processing, combined with the NI USB-6353 DAQ the data acquisition system can be built rapidly. Monitoring test of pulse rate and oxygen saturation in 10 patients, and compared with the data of monitor and prototype, the oxygen saturation measured average error is 0.2%, and the average error of measurement of pulse rate is 0.8 time/min. The results show that the design and clinical use of the blood oxygen saturation monitor have good consistency, so this method can measure the pulse rate and blood oxygen saturation, can be a supplement to the existing physiological parameter monitoring method.
