Intraoperative Mechanical Ventilation and Postoperative Pulmonary Complications After On-pump Cardiac Surgery in High-risk Patients

"Tidal Volume (Vt) =6-8 mL/kg of predicted body weight (PBW), Peep=8 cmH2O, recruitment maneuvers=30cm H2O every 30 min after intubation (except during CPB), after any disconnection and at the admission in ICU.~Recruitment maneuvers are performed in accordance with the surgical team an if SAP≥90 mmHg or MAP≥65 mmHg.~Ventilation is maintained during CPB Vt=2.5 mL/kg, Peep= 5 cmH2O"

Vt=6-8 mL/kg of PBW, Peep=5 cmH2O , No recruitment maneuvers. Ventilation maintained during CPB Vt=2.5 mL/kg, Peep= 5 cmH2O.
