Effect of Oxygen on Health Quality of Life in Patients with COPD: Transient Exertional Hypoxemia

What is it about?

Ambulatory oxygen helps acute exercise performance in people with chronic obstructive pulmonary disease (COPD). However, this improvement may not help in terms of symptomatic benefit for patients during everyday activities. This study looks at a series of individual randomized controlled trials in order to measure the effect of oxygen in patients with COPD. Particularly in patients who do not meet the criteria for mortality reduction with long-term oxygen therapy.

Why is it important?

This study is important as our findings do not support the general application of long-term ambulatory oxygen therapy for patients with COPD especially those who do not meet the criteria for mortality reduction with long-term oxygen therapy.
