Review challenges use of home oxygen for moderate hypoxaemia

Pooled data from high-quality studies suggest guidelines may need to be brought up to date, leading physicians say

Home oxygen provides no survival benefit in patients with COPD and moderate hypoxaemia, nor does it reduce the rate of hospitalisations, according to findings from a potentially practice-changing study.

International researchers say there is little evidence to support the widespread use of long-term oxygen therapy (LTOT) or nocturnal oxygen therapy in this patient population.
