Breath sniffing test could spot lung trouble in ventilator patients
NCT ID NCT06189924
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a new way to check the health of ICU patients who are on breathing machines. Researchers collect a small sample of the air patients breathe out and analyze its proteins. They also take a blood sample to look for related changes in DNA, RNA, and other molecules. The goal is to find patterns that signal early signs of lung problems, so doctors can act faster.
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 lead to a simple, non-invasive breath test that helps doctors detect lung complications earlier in critically ill patients.
- What could go wrong
- This is an early observational study, not a treatment trial. The patterns found may not be specific enough to reliably diagnose conditions in real time.
