Figure 3 Relative changes in regional cerebral oxygenation (rSO2) and middle cerebral artery blood velocity (V-MCA) ipsilateral to the surgical side, mean arterial pressure (MAP), and heart rate (HR) from baseline in response to a recruitment maneuver (RM) and sham maneuver (SM), respectively. Changes in ipsilateral side (I) and contralateral side (C) were also compared. Values are mean±SD. (A) Changes of rSO2 comparison; # P<0.05, RM-IrSO2 vs SM-IrSO2; ## P<0.05, RM-CrSO2 vs SM-CrSO2; (B) Changes of V-MCA comparison; # P<0.05, RM IV-MCA vs SM IV-MCA and RM IV-MCA vs RM CV-MCA; ## P<0.05, SM IV-MCA vs SM CV-MCA; (C) Changes of HR comparison; # P<0.05, RM-HR vs SM-HR; (D) Changes of MAP comparison; # P<0.05, RM-MAP vs SM-MAP.
