Rochester, Minnesota 55905


Purpose:

Although drug therapies and pulmonary rehabilitation have greatly improved COPD symptoms, as many as 50% of patients with severe COPD have inadequately controlled dyspnea. Device-guided breathing is a behavioral intervention that guides respiratory rates into a therapeutic range; prolongation of the expiratory phase improves hyperinflation, the most significant driver of dyspnea in this population. Device-guided breathing, has no known side-effects, and may represent a cost effective adjunctive treatment for dyspnea in severe COPD.


Criteria:

Inclusion Criteria: - Current or former cigarette smokers of at least 10 pack-years - Clinically significant dyspnea, as determined by a score of at least 2 on the Medical Research Council Dyspnea Score questionnaire (0-4), or through pulmonary function test results of a residual volume (RV) of > 150% predicted or an FEV1 of <65% predicted - Clinical diagnosis of chronic obstructive pulmonary disease Exclusion Criteria: - Unable to use the slow-breathing device due to hearing impairment - Poor motivation or lack of interest in using the device - Pulmonary Rehabilitation ordered as a new therapy at the time of enrollment
