Ultrasound may predict breathing readiness without tube blocking
NCT ID NCT07564258
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This study will test whether ultrasound measurements of the diaphragm can estimate a standard breathing effort test (P0.1) in 40 intubated patients. During a spontaneous breathing trial, researchers will compare diaphragm movement and thickness with the P0.1 reading. If the ultrasound matches well, it could offer a non-invasive way to assess breathing drive in patients who cannot have the standard test.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- diaphragm ultrasound
- What this could lead to
- If successful, this could lead to a simpler, non-invasive way to measure breathing effort in patients on breathing machines, helping doctors decide when to remove the tube.
- What could go wrong
- This is a small, early-stage study (40 participants) that only tests a correlation, not a treatment. The ultrasound method may not be accurate enough to replace the standard test in all patients.
