New ultrasound technique could help prevent lung injury in ventilator patients
NCT ID NCT03405779
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study is testing a new ultrasound tool that measures how much the lungs stretch (strain) in patients on breathing machines in the ICU. The goal is to collect initial data from 10 adults with lung disease to see if this technique can help doctors better monitor and prevent lung damage caused by ventilation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lung ultrasonography
- What this could lead to
- If successful, this could lead to a new way to monitor lung health in ventilated patients and help prevent ventilator-induced lung injury.
- What could go wrong
- This is a very small pilot study with only 10 patients, so results may not apply broadly. The tool is experimental and not yet proven to improve outcomes.
