Abstract
Background Minimising hypoxemia during submaximal walking tests has a positive effect on exercise capacity and dyspnea in patients with COPD on long-term oxygen therapy (LTOT). However, the impact of optimising oxygenation during everyday tasks remains unexplored. Therefore, we investigated the effects of maintaining a target saturation on activities of daily living (ADL) using automated oxygen titration compared to conventional fixed oxygen flow.
