P<0.05. Compared with Group VCV, PIP in Group PCV-VG was significantly reduced (P=0.01) and Cdyn was significantly increased at T2 (P=0.01). There were no significant differences in artery blood gas between both groups at T2 (P>0.05). PIP – peak inspiratory pressure; Cdyn – pulmonary dynamic compliance. T2 – one-lung ventilation 30 min.
