Brief Summary
The primary objective of the study is to evaluate the efficacy of Helium/Oxygen (He/O2) 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.

Study Arms (2)
Helium/Oxygen
EXPERIMENTALHelium/Oxygen 78%/22% will be administered for a maximum of 72 hours.
Air/Oxygen
ACTIVE COMPARATORAir/Oxygen will be administered for a maximum of 72 hours.
Interventions
The Helium/Oxygen mixture will be administered during NIV and NIV-free sessions for a maximum of 72 hours using study dedicated devices. Patients will then receive the Air/Oxygen mixture with usual devices.

Eligibility Criteria
You may qualify if:
- Patient with known or suspected COPD
- Patient presenting current exacerbation of COPD with hypercapnic acute respiratory failure
- Patient eligible for Non-Invasive Ventilation (NIV)
- Patient admitted in an ICU
You may not qualify if:
