The Lung Flute uses patented low-frequency acoustic wave technology for optimal secretion clearance and bronchial hygiene. The patient exhales through a mouthpiece over a reed inside the horn of the Lung Flute. The resulting acoustic wave travels retrograde into the lower airways and lung parenchyma, and increases mucociliary clearance.
Unlike conventional respiratory devices, the Lung Flute acoustic wave technology clears and mobilizes secretions deep in the lungs so they are easier to expectorate.
