Official title: Outcome Comparisons of Two Vibratory Positive Expiratory Pressure Devices in Patients Unable to Clear Airway Secretions

Run by Rush University Medical Center · NCT05873504 · Data updated 2026-11-12

This study is testing whether a high oscillatory airway clearance device works better than a low oscillatory one for helping adults clear mucus from their lungs.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18 years or older with a RAAT score of at least 10 and a secretion score of at least 5.

Probably not a fit

Patients younger than 18, pregnant individuals, or those with severe respiratory limitations may not benefit from this study.

What this trial studies

This pilot study is a randomized control trial that aims to compare the effectiveness of a high oscillatory index device versus a low oscillatory index device in clearing airway secretions in adult patients. Participants will be adults aged 18 and older who meet specific respiratory assessment criteria. After randomization, patients will receive instructions on how to use the assigned device, and their clinical outcomes will be monitored until discharge from the hospital. The primary outcome measured will be the RAAT score, which assesses various respiratory parameters.

Why it matters

Potential benefit: If successful, this study could improve airway clearance techniques for patients with respiratory impairments.

How similar studies have gone: Other studies have explored airway clearance devices, but this specific comparison of oscillatory index devices is novel.
