Study Arms:
- Sham Bi-PAP (Type: SHAM_COMPARATOR): Sham Bi-PAP was applied through nasal mask for 3 days postoperatively. Sham Bi-PAP was created by introducing a hole at the connection of the mask with the spiral tube of Bi-PAP. With this modality, also used on previous studies, the applied pressure by sham Bi-PAP was constant and equal to 2 centimeter of water (cm H2O).
- Bi-PAP (Type: ACTIVE_COMPARATOR): Bi-PAP through nasal mask, at individualized IPAP/EPAP pressures, was applied for 3 days postoperatively. IPAP and EPAP in the Bi-PAP system were individualized for each patient in accordance with accepted values of SpO2, PaCO2, and patient synchronization and tolerability with the device.Individualized setting of pressures in patient group was applied gradually starting with 12/4 cm H2O (IPAP/EPAP) and up to 18/10 (IPAP/EPAP) with consecutive increases of 2 cm H2O.

Based on this trial design, predict the completion outcome and termination type (if applicable).
