Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This will be a randomized, cross-over trial evaluating the efficacy of nasal high-flow oxygen therapy (HFOT) vs. low-flow oxygen therapy (LFOT) on cycling endurance in patients with chronic obstructive pulmonary disease (COPD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This will be a randomized, cross-over trial evaluating the efficacy of nasal HFOT vs. LFOT on cycling endurance in patients with COPD. Each patient will perform two constant load cycling exercise tests to exhaustion using HFOT and LFOT on two consecutive days, respectively, according to randomization. The load of the cycle ergometer will be set at 75% of the individually estimated maximum work rate (Wmax). During exercise tests, LFOT will be provided by a standard nasal cannula at a flow rate of 3 L/min using an oxygen concentrator. HFOT will be applied by a dedicated large bore nasal cannula at a flow rate 60 L/min, FiO2 45%, temperature 32 °C, using a HFOT device.
