PaCO (mmHg)	38±4	31±8^*	37±4	40±6^**
^* ^** CrSO – the rSO value of the contralateral side; CV-MCA – the V-MCA value of the contralateral side; HR – heart rate; IrSO – the rSO value of the surgical side (ipsilateral rSO); IV-MCA – the V-MCA value of the surgical side (ipsilateral V-MCA); MAP – mean arterial pressure; PaCO – arterial partial pressure of carbon dioxide; RM –recruitment maneuver; SM – sham maneuver.
