Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The duaration of time from the incision of pleura to satisfactory lung deflation (verbal rating scale = 8); | — |
Secondary
| Measure | Time frame |
|---|---|
| the lung collapse scale at 1, 5, 10, 20, 30 and 40 min after pleural opening using a verbal rating scale from 0 (no lung deflation) up to 10 (complete collapse).;Arterial blood gases were obtained preoperatively while patients were breathing room air, and at 0, 20, 40 min after pleural incision.;incidence of hypoxemia (SPO2<90%) and the need for CPAP; | — |
