Impact of Lung Flute Therapy on Asthma

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.
