Lung Ultrasound Evaluation of the Effects of PEEP and Recruitment Strategies Adjusted for Intraoperative Dynamic Compliance on Postoperative Respiratory Complications in Obese Patients Planned for Laparoscopic Surgery

In order to find the individualized optimal PEEP value, PEEP will be increased at 2-minute intervals with a maximum peak pressure of 45 cmH2O and a driving pressure of 15 cmH2O. Recruitment will be performed. When the target is reached, the PEEP value will be adjusted to the value at which the highest dynamic compliance is achieved by decreasing it.
