About

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.

Full description

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.

Enrollment: 19 patients

Sex: All

Ages: 45 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

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

Exclusion criteria

• Evolutive heart disease.
• Unability to understand or realize the tests.
• Acute exacerbation during the last month.
