Device-guided Breathing for Shortness of Breath in COPD

Not Applicable

Completed

• Conditions: COPD; Dyspnea; Hyperinflation
• Interventions: Behavioral: Twice daily practice of device-guided slow breathing.

• Registration Number: NCT01286181
• Lead Sponsor: Mayo Clinic

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Device-guided slow breathing	Twice daily practice of device-guided slow breathing.	-

Primary Outcome Measures

Name	Time	Method
Determine effect of increased device-guided breathing on health-related quality of life measures.	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.

Secondary Outcome Measures

Name	Time	Method
Evaluate effect of device-guided slow breathing on daily physical activity.	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.
