Detailed Description:

the purpose of this study is to evaluate the distance walked by patients with severe Chronic Obstructive Pulmonary Disease (COPD) during a Six-Minute Walk test (6MWT) while breathing Helium/Oxygen 65%/35% compared to either breathing Nitrogen/Oxygen 65%/35% or receiving Non-Invasive Ventilation (NIV) with a FiO2 of 0.35 and to evaluate exercise related symptoms
