Comparing Two Types of Breathing Support in People With COPD, High Carbon Dioxide Levels, and Sleep Apnea

Sponsor: University of British Columbia

Summary

This pilot study compares two positive airway pressure strategies for patients with both COPD and obstructive sleep apnea (overlap syndrome) who retain excess carbon dioxide. Thirty-two patients will be randomly assigned to either CPAP or high-intensity bilevel ventilation (BiPAP) for 12 months. The primary outcome is change in carbon dioxide levels. Secondary outcomes will be to evaluate the feasibility of conducting a larger multi-centre trial to guide treatment for this underserved population and other measures including sleep quality, respiratory symptoms, quality of life, treatment adherence, side effects, and safety.
