Cheap nebulizer could bring cough testing out of the lab
NCT ID NCT07531901
First seen Jun 27, 2026 · Last updated Jul 21, 2026 · Updated 2 times
Summary
This study tests whether a simple, handheld nebulizer can reliably measure how sensitive a person's cough reflex is, compared to expensive lab equipment. Ten healthy adults will take part, each using both methods. The goal is to see if the cheaper device gives consistent results, which could make cough testing more widely available.
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 make cough sensitivity testing cheaper and more accessible outside specialized labs.
- What could go wrong
- This is a very small, early feasibility study with only 10 healthy adults. Results may not apply to people with cough conditions or in real-world settings.
