抄録

Venous blood oxygen saturation in tissues is important to estimate tissue metabolisms. In the present study, noninvasive method to measure venous blood oxygen saturation in tissues was developed using a near-infrared-light absorption technique. A sensor of reflection type consisted of an optical fiber(connected to two light-emitting diodes)and three photo diodes. Light absorption signals were obtained from the sensor with and without loading of a 100g-weight at the hill of thumb in five healthy subjects. When the venous blood oxygen saturation in tissues was calculated on the basis of the differences in the absorption signals, the venous blood oxygen saturations in tissues obtained from the present method were well correlated with those obtained from blood samples at the cubital vein.
