Summary

Chronic obstructive pulmonary disease (COPD) is a serious respiratory disease in which the airways in the lungs are partially blocked, resulting in symptoms of chest tightness, coughing, and difficulty breathing. Currently, there are many available treatments for managing COPD symptoms and improving quality of life, including medications, lifestyle changes, oxygen therapy, and pulmonary rehabilitation. For people with severe COPD that is characterized by very low blood oxygen levels at rest, long term oxygen therapy can help to prolong life and promote feelings of well-being. However, the effectiveness of supplemental oxygen therapy for people with COPD that is characterized by only moderately low blood oxygen levels at rest or normal blood oxygen at rest and desaturation on exercise is not known. This study will evaluate the effectiveness of supplemental oxygen therapy in treating people with COPD who have moderately low blood oxygen levels at rest or who have normal blood oxygen levels at rest, but have low or very low blood oxygen levels during exercise.

Conditions

Interventions

DRUG

Supplemental oxygen therapy

Oxygen dose at rest and during sleep will be 2 L/min via nasal cannula. The oxygen dose used while walking will be individually prescribed and will be sufficient to maintain oxygen saturation at 90% or above for at least 2 minutes while walking. Participants who have low blood oxygen levels at rest will be instructed to use oxygen 24 hours per day. Participants who have normal resting blood oxygen levels, but low or very low blood oxygen levels during exercise, will be instructed to use oxygen during physical activity and sleep.
