Chest vibrations may boost lung sample collection
NCT ID NCT07751705
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether a device that sends gentle vibrations through the chest can help people with COPD cough up more sputum (mucus) during a standard collection procedure. Each participant undergoes the procedure twice—once with the device and once without—to compare the amount of sample obtained. The goal is to see if the device improves sample yield, which could enhance research on lung diseases.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- A vibroacoustic device applied to the chest during sputum collection
- What this could lead to
- If effective, this device could improve sputum collection in COPD, aiding research and diagnosis of lung diseases.
- What could go wrong
- The trial is small (20 participants) and early, so results may not apply broadly. The device may not increase sputum yield or could cause discomfort.
