Developmental phase
Assessment
Primary outcomes
Radiological atelectasis score of the dependent lung just after surgery
Key secondary outcomes
*Radiological atelectasis score of the dependent lung on postoperative day (POD)1
*PaO2/FIO2 ratio just after surgery and on POD1
*Time-weighted average of SpO2 and FIO2 during surgery
*Sequential Organ Failure Assessment (SOFA) score on POD1 and POD2
*Postoperative complications within 7 days following surgery (Clavien-Dindo classification grade =>III)
*AKI within 2 days following surgery (defined using KDIGO creatinine criteria)
*Hospital-free days at 28 days
*Hypoxemia during surgery (SpO2 <88% continues for more than 2min)
*Severe hypoxemia during surgery (SpO2 =<85% continues for more than 2min)
