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). | ||||
