A study of the clinical utility of cerebral and somatic mixed blood oxygen saturation measurement using a noninvasive monitor of mixed blood oxygen saturation (INVOS) during pediatric congenital heart surgery. - A study of the clinical utility of cerebral and somatic INVOS during pediatric congenital heart surgery.

Through the whole surgical period, ScO2 correlated strongly with mean blood pressure regardless of the physiological type. On the other hand, the contribution of mean blood pressure to SrO2 was weak and various other parameters were related to SrO2 changes. Thus, the physiological parameters affecting ScO2 and SrO2 were rather different.
