A new randomized controlled trial published in The Lancet shows no meaningful benefit from home oxygen therapy for patients with fibrotic interstitial lung disease who experience low blood oxygen only during activity.
The study challenges long-standing assumptions that ambulatory oxygen improves quality of life or exercise tolerance in this group, despite its widespread use in clinical practice.
What the trial actually found
Should current users stop oxygen therapy?
No — any changes to therapy should be discussed with a healthcare provider, as individual responses vary and oxygen may still facilitate some patients subjectively even if average trial results are negative.
The study only addressed isolated exertional hypoxemia; it did not evaluate patients with resting hypoxemia or those requiring oxygen for other complications like pulmonary hypertension.

Clinicians should reassess individual demand, considering potential burdens like cost, equipment management, and social stigma, especially when objective benefits are absent.

No — any changes to therapy should be discussed with a healthcare provider, as individual responses vary and oxygen may still facilitate some patients subjectively even if average trial results are negative.
Patients may continue using oxygen due to symptom relief or habit, but the evidence no longer supports routine prescription for exertional hypoxemia alone in fibrotic ILD.

That earlier study reported quality of life gains, but its design limits reliability, and subsequent lab-based studies showing transient benefit during exercise tests do not translate to real-world use.

The American Thoracic Society guideline supports ambulatory oxygen for ILD patients with exertional desaturation based on a single small, unblinded crossover study from two decades ago with only two weeks of treatment.

Secondary endpoints including six-minute walk distance, dyspnea scores, and physical activity levels also showed no clinically important improvement with oxygen therapy.

There was no significant difference between groups in the primary outcome of health-related quality of life measured by the St. George’s Respiratory Questionnaire.

Researchers in Australia enrolled patients with ILD and isolated exertional hypoxemia, assigning them to either active oxygen or medical air delivered via nasal cannula during daily activities over 12 weeks.
