Breath test may guide ICU nutrition, boost survival
NCT ID NCT07457554
First seen Jun 24, 2026 · Last updated Sep 11, 2026 · Updated 3 times
Summary
This study tests whether using a breath measurement called respiratory quotient (RQ) can help doctors give the right amount of calories to ICU patients on ventilators. 200 patients will be randomly assigned to either standard nutrition care or nutrition tailored to their RQ. The goal is to see if this personalized approach improves survival and reduces time on a ventilator.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- RQ-guided nutrition therapy
- What this could lead to
- If successful, this could lead to a simple way to tailor nutrition for ICU patients, potentially reducing complications and improving survival.
- What could go wrong
- This is a relatively small, early-stage study (200 patients) and the approach is still experimental. It may not show a clear benefit over standard care, and results may not apply to all ICU patients.
