Summary

This study tests whether a special ventilator mode called APRV can improve breathing and oxygen levels in very obese patients after elective heart surgery. About 180 adults with a BMI of 40 or higher will be randomly assigned to receive either APRV or standard ventilation after surgery. The goal is to see if APRV reduces lung problems and shortens ICU stays.
