Study Summary
The seated or "beach chair" position during surgery and general anesthesia decreases brain oxygen levels and can result in stroke. As such, poor neurological outcome following beach chair positioning is a growing concern. In the proposed study the investigators test the hypothesis that changes in ventilation strategy and anesthetic technique can affect cerebral oxygenation in anesthetized patients in the beach chair position.
Primary Outcome
rSO2 will be recorded as a "snap shot." A mean value from right and left sides will be calculated for each patient at each study point. Set Point 1: FIO2 30% (70% nitrogen), PETCO2 30mmHg - supine position. Set Point 2: FIO2 30% (70% nitrogen), PETCO2 30mmHg - beach chair position. Set Point 3: FIO2 100%, PETCO2 30mmHg - beach chair position. Set Point 4: FIO2 100%, PETCO2 45mmHg - beach chair position. Set Point 5: FIO2 30% (70% nitrogen), PETCO2 30mmHg - beach chair position. With each set p
