Summary

This study looked at 140 adults having lung surgery to see if setting the breathing machine based on each person's own lung capacity (forced vital capacity) works better than using a standard formula based on height and weight. The goal was to find out which method keeps lungs working well during and after surgery. Researchers measured oxygen levels, lung stiffness, and checked for complications like pneumonia or air leaks after the operation.
