Many chronic obstructive pulmonary disease patients suffer from dyspnoea and reduced physical abilities. Some of the patients exhibit desaturation during physical exercise. Few studies have examined if oxygen therapy during physical exercise can relieve symptoms and improve outcomes of pulmonary rehabilitation. These studies show that oxygen therapy during exercise results in significant improvement in exercise capacity. Yet it is not possible to draw a clear conclusion regarding the effects of more prolonged (weeks) treatment. The studies are in general small and of poor methodological quality.
许多慢性阻塞性肺疾病患者存在呼吸困难和身体能力下降的问题。一些患者在体育锻炼期间会出现血氧饱和度降低的情况。很少有研究探讨体育锻炼期间进行氧疗是否能缓解症状并改善肺康复的效果。这些研究表明，运动期间进行氧疗能显著提高运动能力。然而，对于更长时间（数周）治疗的效果，目前还无法得出明确结论。总体而言，这些研究规模较小，方法学质量较差。
