The Lung Flute, a small hand held device, generates acoustic (sound) waves, which loosen, mobilize, and eliminates secretions deep in the lungs.
Generates resonance like a string instrument
Thins secretion by activating the aqueous phase and breaking the hydrogen bonds thinned Secretion, results in Patient coughing and clearing
Physiology of the Lungs
Human lungs possess a natural means for clearing lung secretions. Natural rhythmic 'beating' motion of cilia creates vibration between 16-25Hz. Frequency of oscillation keeps mucus phase in a liquid state, mucus fluid can now be easily moved by natural motion of cilia and Mucus is expelled by coughing or swallowing
Physics of the Lung Flute Acoustic sound waves are amorphous, and will travel deeper into the lung structure than conventional pulsed air device
Patient exhales through the Lung Flute -operating pressure of 2.0-2.5cm H2O
Reed oscillation, horn design and lung cavity act in parallel to produce sound frequency making the secretions thinner and more easily expelled by coughing. Lung Flute operation act in parallel to produce sound frequency between 16-25Hz.
Lung Flute supplements the natural mucus clearing system by artificially vibrating the airways and cilia.
The Advantages of Applied Acoustics
COPD, Asthma, Pneumonia, Tuberculosis, Lung Cancer, Cystic Fibrosis
Airway Clearance / Bronchial Hygiene Therapy
The Lung Flute is a non-invasive device designed to improve gas exchange by mobilizing and
removing retained airway secretions
Genotyping pulmonary TB, identifying infectious agents & inflammatory markers, cell-typing pneumonia, early detection of lung cancer
Drug discovery and research requiring deep lung sputum samples

Government Regulatory Clearances
"The Lung Flute provides physicians with a modality to help patients clear their lungs of debilitating lung congestion and take more control over managing their COPD"
Sanjay Sethi, MD FACP Division Chief, UB School of Medicine
"The Lung Flute is really an excellent device. Everyone that I gave it to has said it is the best thing they have ever used, even my very severe asthmatic patients who struggle with secretions"
Serpil Ezurum MD, Pulmonary, Allergy, and Critical Care Medicine -Cleveland
"The device allows our therapists to focus their treatment times on functional training instead of performing conventional manual chest percussion/vibration for secretion clearance. The results have shown improved secretion clearance by the patient and increased efficiency in the utilization of our staff/treatment times based on functional improvement"
Marc Goldberg, MPT, Director Physical Therapy -NYU Medical Center
