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.

Conditions

• COPD
• Dyspnea
• Hyperinflation

Interventions

Type	Name	Description
BEHAVIORAL	Twice daily practice of 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.
