Supplemental oxygen improves exercise capacity in IPF patients with exertional desaturation

ABSTRACT Background and objective The efficacy of supplemental oxygen during exercise remains unclear for patients with IPF, as there have been conflicting results from recent prospective studies with small sample sizes. Methods This prospective, single‐blind, randomized, crossover trial evaluated the efficacy of supplemental oxygen compared with placebo air during exercise in consecutive patients with IPF without resting hypoxaemia at initial evaluation. Patients with
