Abstract
The blood oxygen saturation is an important human physiological parameter. Currently,the blood oxygen saturation detection method is divided into the invasive measurement of blood oxygen saturation and noninvasive measurement of blood oxygen saturation based on photoplethysmography method. Among them,based on photoplethysmography method of noninvasive oxygen saturation research model adopts photoelectric volume pulse wave signals of the human body as an information carrier for noninvasive continuous blood oxygen saturation detection. This paper reviews noninvasive oxygen saturation based on photoplethysmography method measurement principle and measurement system,mainly introduces the reflectance oxygen saturation detection system. And the related factors affecting the accuracy of the noninvasive blood oxygen saturation measurement system were concluded and summarized.
