Withdrawn

• Conditions: Chronic Obstructive Pulmonary Disease

• Registration Number: NCT00972868
• Lead Sponsor: Massachusetts General Hospital

Brief Summary

The purpose of this study is to determine the feasibility, safety and efficacy of a unidirectional breathing mask (breathe in through the nose and out through the mouth or breathe in through the mouth and out through the nose) in COPD patients with breathing difficulties requiring noninvasive positive pressure ventilation (NPPV).
