Tailored breathing settings during obesity surgery may reduce lung complications

This study tested whether adjusting breathing machine pressure (PEEP) to each patient's lung stiffness during laparoscopic weight-loss surgery improves oxygen levels and reduces lung collapse afterward. 40 adults with obesity (BMI over 30) were randomly assigned to either a fixed pressure or a personalized pressure based on real-time lung measurements. The goal was to see which approach leads to better breathing and fewer complications after surgery.
