The purpose of this study is to compare differences in oxygen delivery between portable oxygen concentrators (POCs) and liquid oxygen (LOs) portable units, pose a question if POCs are equally effective as LOs in reducing exercise-induced hypoxaemia. DESIGN: Randomized, single-blind clinical trial.
Our primary objective is to compare at rest and during exercise the evolution of oxygen saturation and dyspnea during 6 minutes walking test in patients with COPD receiving oxygen supplementation either with portable concentrators or liquid oxygen in a random order.
