Tummy tuck breathing study: does surgery pressure harm lungs?

This study looks at how changing the air pressure in a patient's lungs during a tummy tuck (abdominoplasty) affects their breathing after surgery. Researchers will measure lung pressure before and after the surgeon tightens the belly muscles, and then check lung function afterward. The goal is to learn how to make this common cosmetic surgery safer for the lungs. The study will include 120 adults aged 20 to 50 who are healthy enough for surgery.
