Could a simple ultrasound replace invasive lung pressure tests?
NCT ID NCT07253480
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study checks if a special ultrasound technique (shear-wave elastography) can accurately measure diaphragm pressure without needles or tubes. Twelve healthy adults will perform breathing exercises while researchers compare ultrasound readings to standard pressure measurements. If it works, this could lead to safer monitoring for lung disease patients.
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 non-invasive way to monitor lung pressure, helping prevent complications in COPD patients after lung surgery.
- What could go wrong
- This is a very early feasibility study with only 12 healthy adults. It may not work in real patients, and the ultrasound method might not be accurate enough.
