Device-guided Breathing for Shortness of Breath in COPD
April 1, 2013 updated by: Roberto P. Benzo, Mayo Clinic
Device-guided Slow Breathing in COPD Patients With Clinically Significant Dyspnea: Phase 2
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Device-guided slow breathing
|
Participants are asked to use the slow-breathing device for 20 minutes twice daily, for 8 weeks.
Participants receive weekly telephone calls to monitor device use and are encouraged to use pursed-lips when following the breathing tones of the device while exhaling.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Determine effect of increased device-guided breathing on health-related quality of life measures.
Time Frame: 8 weeks
|
Pre and post device use measures of dyspnea, health-related quality of life, stress, adn self-efficacy for managing chronic disease will be obtained through self-administered questionnaires.

Measure Description |
Time Frame |
---|---|---|
Evaluate effect of device-guided slow breathing on daily physical activity.
Time Frame: 8 weeks
|
Evaluate the effect of a higher intensity of device-guided breathing (20 minutes twice daily for 8 weeks) on daily physical activity, as measured by a gold-standard activity monitor, before and after device use.
