COPD
Conditions
Brief summary
This is a 26 week randomized controlled study. The study consists of, in order, an enrollment visit, followed by clinic visits at 2 weeks, 14 weeks and at 26 weeks. There will also be telephonic assessments at 8 weeks and 20 weeks. Clinic visits will involve comprehensive assessments of the patients lung condition, including post-bronchodilator spirometry, Shuttle walk distance, BODE index, health status (SGRQ) and symptoms (CCQ). Sputum and serum samples will also be collected at these visits for microbiological and inflammation analysis. Sputum will be obtained with the Lung Flute as an induction device and Pulse Oximetry will be assessed prior to and after use of the Lung Flute. Clinic and telephonic visits will collect information regarding compliance with the use of the Lung Flute, adverse events and exacerbation history.

Subjects must have a smoking history of at least 10 pack-years. 4. Subjects must have stable disease for at least 1 month prior to enrollment with no changes in the maintenance treatment for COPD in this period. \-
Exclusion criteria

Inability to vibrate the reed of the Lung Flute® consistently because of severely expiratory flow rate. 4. Subject with any evidence of significant concomitant clinical disease that, in the opinion of the investigator, could interfere with the conduct of the study or safety of the subject. 5. Pregnant or nursing females or females intending to become pregnant during the course of the study. 6. Use of any investigational drug within one month or 6 half-lives (which-ever is greater) of the enrollment visit. 7.
