Oxygen Therapy during Exercise in Patients with Interstitial Lung Diseases

Area of Science:

• Pulmonology
• Critical Care Medicine

Background:

• Interstitial lung diseases (ILDs) are a group of lung diseases causing significant morbidity and mortality.
• Current ILD treatments slow disease progression but do not offer a cure.
• The role of oxygen therapy in managing ILDs remains unclear.

Purpose of the Study:

• To evaluate the existing literature on oxygen therapy's impact on mortality in ILD patients.
• To determine if oxygen therapy serves a supportive role or offers survival benefits.

Main Methods:

• A systematic literature review of studies published since 2010 concerning oxygen therapy during exercise in ILD patients.
• Exclusion of studies utilizing cardiopulmonary tests, focusing solely on the 6-minute walking test (6MWT) or free walking tests.
• Inclusion of 11 relevant articles.

Main Results:

• Most studies indicated improved oxyhemoglobin saturation during exercise with oxygen administration.
• The AmbOx study (2018) demonstrated significant quality of life improvements for patients using oxygen during daily activities.
• One Japanese study reported different findings regarding oxygen saturation.

Conclusions:

• The current body of literature lacks sufficient evidence to establish specific guidelines for oxygen therapy in ILDs.
• It remains inconclusive whether oxygen therapy impacts ILD patient mortality or merely provides supportive care.
