Abstract (in Japanese) (See Japanese page) 
(in English) A new calibration method using a non linear multivariate regression method, support vector machines regression (SVMsR) of pulse oximetry was attempted. Two photo plethysmograms (PPGs) by red and IR were measured on five subjects. Simultaneously, oxygen saturation (SpO_2) level was measured by a commercial pulse oxymeter. SpO_2 level was controlled by breathing 10% oxygen gas for obtaining 98-75% SpO2 level. Sequentially, feature points of two PPGs were extracted in beat by beat. Then, SVMsR were attempted to obtain regression model between SpO_2 by meter and the feature points of PPG. Finally, the regression model was evaluated by unknown data. The root mean squared error is 1.90 [SpO_2 level %]. In conclusion, SVMsR might be applicable on calibration for pulse oximetry.
