Benefits of an oxygen reservoir cannula versus a conventional nasal cannula during exercise in hypoxemic COPD patients: a crossover trial.

摘要

We show that O2 delivery via the Oxymizer is superior to a CNC with regard to endurance capacity and oxygenation during exercise in patients with severe COPD. It seems that patients with a higher demand for O2 (≥ 4 liters/min), in particular, may benefit more from the use of the Oxymizer.
