Impact of Lung Flute Therapy on Asthma

NCT02003521 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 48

Summary

We hypothesized that the ability of the Lung Flute to enhance mucus clearance from the lower airways could be used to improve asthma control, if the device is used on a chronic basis. The primary end point of the study is the comparison of Asthma Control Test (ACT) - a validated questionnaire for asthma control and exhaled NO before, during and after using the lung flute. Several secondary end points were assessed for efficacy and safety, including health status, spirometric lung function, "stepping down" controller therapy and daily albuterol use.

Conditions

  • Persistent Asthma

Interventions

DEVICE

Lung Flute

A low frequency wave is generated at the mouth by exhaling through a mouthpiece over a laminar surface (Reed) inside the Lung Flute®. The resulting low frequency acoustic wave that is produced travels retrograde into the lower airways and lung parenchyma and increases mucociliary clearance. Patients expel air with the force required to blow out a single candle. Patients concentrate on producing a low tone through the device while breathing in a proscribed pattern. Twenty repetitions of a single two-breath pattern are performed with the device to complete a diagnostic session.
