Figure 2. Brain tissue PO2, PCO2, pH, and blood flow during 9% desflurane and middle cerebral artery occlusion in patient 3. Desflurane increased blood flow, PO2, and pH and decreased tissue PCO2. Middle cerebral artery occlusion produced a decrease in tissue PO2without a change in pH or P (CO)2. This patient had a good recovery.
