Can personalized breathing settings protect lungs during heart surgery?
NCT ID NCT07044089
First seen Sep 03, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This trial tests whether tailoring breathing support to each patient protects the lungs better than a standard fixed setting during heart bypass surgery. Researchers will compare two methods of setting positive end-expiratory pressure, or PEEP, in 86 adults having on-pump coronary artery bypass grafting. They will measure oxygen levels, lung function, and heart stability during surgery, then track breathing complications, time on a ventilator, and length of hospital stay afterward.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Individualized positive end-expiratory pressure (PEEP) guided by driving pressure, compared with a fixed PEEP level, during lung-protective ventilation
- What this could lead to
- If individualized PEEP works better, it could reduce lung complications and shorten hospital stays for people having heart bypass surgery.
- What could go wrong
- This is a single-center trial with 86 participants, so results may not apply to all patients. Individualized PEEP may not improve outcomes and could affect blood pressure or heart function during surgery.
