Measuring lung pressure during surgery to improve ventilator safety
NCT ID NCT05859672
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study observed 150 adults undergoing elective surgery with general anesthesia. Researchers used an esophageal balloon to measure how changes in ventilator settings (tidal volume and PEEP) affect pressure inside the lungs and chest. The goal was to better understand these pressure changes and how they relate to blood flow, which may help guide safer ventilator use in the future.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors choose safer ventilator settings during surgery to protect patients' lungs.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures pressure changes and does not test any new therapy or device.
