两组患者不同时间点HR、MAP、Ppeak的比较

Comparison of HR, MAP and Ppeak between the two groups at different time points (Mean±SD, n=23)

Index	Group	T0	T1	T2	T3	F	P △
HR: Heart rate; MAP: Mean arterial pressure; Ppeak: Peak airway pressure; T0: Before the start of single lung ventilation; T1: Single lung ventilation for 30 min; T2: Single lung ventilation for 60 min; T3: Both lungs resumed ventilation for 30 min. aP<0.05 vs T0, bP<0.05 vs T1, cP<0.05 vs T2; △: Intra-group comparison; ☆: Compared with control group.
