WebResults: We noted 14 episodes of simultaneous decreases in Sr (O (2)) and BIS during acute hypotension in five children. An acute decrease in BIS, which coincided with a decrease in Sr (O (2)) suggesting a reduction in cerebral blood flow, was associated with acute slowing of the raw EEG waveforms. WebAlthough ephedrine increases blood pressure and CBF, it has also been reported to increase BIS values directly. 20 Similar to cerebral oximetry, BIS and other processed EEG monitors analyze EEG signals from the frontal …
