New lung monitor aims to prevent breathing problems after surgery
NCT ID NCT06899295
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watches how the lungs work during surgery in 34 adults under general anesthesia. It uses special monitors to measure lung pressure and air distribution during a routine breathing technique called alveolar recruitment. The goal is to see if these monitors can help doctors set the ventilator more safely and reduce the risk of lung injury after surgery.
