Patients will be shifted to 100% Oxygen then; the recruitment maneuver will be performed by manual inflation with a pressure of 30 cmH2O for 30 seconds.
Patients will be shifted to 100% Oxygen then; the recruitment maneuver will be performed under the direct real-time guidance of ultrasound if atelectasis (defined as LUS of ≥ 2 for any of the 12 regions) is present. This will be done by manual inflation with a pressure of 10 cmH2O for 10 seconds, increased 10 cmH2O every 10 seconds until no collapsed areas are visible on the ultrasound, the maximum airway pressure will be limited to 40 cmH2O. This could be repeated if needed.
