Effect of Ultrasound-assisted Lung Recruitment Maneuver on Preventing Perioperative Atelectasis

in the group 2, in addition to the fixed PEEP of 5 cm H₂O, a recruitment maneuver is planned at the end of the surgery. This will involve administering 6 breaths with VC × 2, I/E ratio of 1:1, and a plateau pressure of less than 35 cm H₂O, before extubation.

In the third group, in addition to the fixed PEEP, a recruitment maneuver will be performed at the end of the surgery before extubation. This will involve administering 6 breaths with VC × 2, I/E ratio of 1:1, and a plateau pressure of less than 35 cm H₂O, with 3 breaths in the right lateral decubitus position and 3 breaths in the left lateral decubitus position
