Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Chronic Obstructive Pulmonary Disease (COPD) affects over 14 million people in the United States. It is the fourth leading cause of death and the only leading cause of death for which mortality rates are rising. Medical science has developed few effective therapies for COPD. In patients with advanced COPD and chronic hypoxemia, long-term oxygen therapy (LTOT) has been shown to be uniquely beneficial. It is the only available non-surgical therapy demonstrated to prolong survival in these patients. This study will compare the clinical and physiologic benefits of two different oxygen therapy devices among hypoxemic individuals with COPD: a lightweight ambulatory oxygen device versus the standard portable E-cylinder device.
