Oxygen Portable Concentrator During Exercises in Patients With COPD

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.

About this study

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.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • COPD with respiratory failure and indication for oxygen supplementation at rest and/or during exercice.

Exclusion criteria
