Table 2. Physiologic Data during the Study

Data are mean ± SD.

*P < 0.05 vs.  corresponding baseline.

MAP = mean arterial pressure; Pco²= partial pressure of carbon dioxide; Po²= partial pressure of oxygen; Sao²= arterial oxyhemoglobin saturation; Sco²= cerebral oxyhemoglobin saturation; Sjo²= jugular bulb oxyhemoglobin saturation.
