E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of Helium/Oxygen 78%/22% compared to a conventional Air/O2 mixture in reducing endotracheal intubation rate and mortality in patients with severe hypercapnic exacerbations of Chronic Obstructive Pulmonary Disease (COPD) during their index Intensive/Intermediate Care Unit (ICU) stay |
