Table 3 Comparison of respiratory mechanics indexes at 4 min after the completion of the one-lung ventilation titration (T2) time point.

Group	DP (cmH2O)	PIP (cmH2O)	PEEP (cmH2O)	Cdyn (mL/cmH2O)
Group O	12.88±2.47	24.12±2.76	11.24±1.71	52.48±5.68
Group C	10.80±1.73	18.48±1.05	7.68±1.28	79.67±11.86
P value	0.01	0.01	0.01	0.01
The results of respiratory mechanics showed that at T2, the driving pressure (DP) value of group O (12.88±2.47 cmHO) was higher than that of group C (10.80 ± 1.73 cmHO) (=0.01), and the peak airway pressure (PIP) and positive end-expiratory pressure (PEEP) values of group O were higher than that of group C (24.12±2.76 cmHO vs 18.48±1.05 cmHO and 11.24±1.71 cmHO vs 7.68±1.28 cmHO, respectively). The dynamic lung compliance (Cdyn) value in group C was higher than that in group O (79.67±11.86 mL/cmHO vs 52.48±5.68 mL/cmHO).
