Primary Outcome Measures:
  • Evolution of daytime PaCO2 of NIV without target volume, with Target volume and with CPAP alone [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Evolution in dyspnea scores (BDI/TDI and Simon Score) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Evolution of subjective and objective sleepness (Osler) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Cardiovascular parameters on Arterial strength (pulse velocity) and Endothelial function (Post ischemic test) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Evolution of blood inflammation (IL6, TNFα et CRP) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Evolution of insulin résistance [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Compliance (hours of treatment) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Evolution of quality of ventilation (Leaks, asynchronism, others events) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Sleep quality (PSG) between the 3 groups at 6 weeks [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
