New study tests best way to keep lungs open during surgery
NCT ID NCT07186920
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 70 adults having surgery to see if a special breathing machine setting (lowest driving pressure) prevents lung collapse better than standard protective settings. Researchers used lung ultrasound to check for collapse right after surgery. The goal was to find which method keeps lungs healthier and may reduce hospital stays or complications.
