Abstract:Backgrounds: There are no clinical data comparing the effect of exercise training using both high fraction of inspired oxygen (FIO2) and high flow through a high-flow nasal cannula (HFNC) with that of ordinary supplemental oxygen on exercise capacity in subjects with chronic respiratory failure (CRF) receiving long-term oxygen therapy (LTOT). Methods: In this randomized study, 32 patients with CRF receiving LTOT were assigned to undergo 4 weeks of exercise training on a cycle ergometer using an HFNC (flow: 50 … Show more
