Patients with OHS are efficiently managed with long term home-based nocturnal noninvasive positive pressure ventilation (NIPPV). Several NIPPV devices offer the feature of automatically adjusting pressure support (and/or respiratory back-up rate) on the basis of a pre-determined "ideal tidal volume" or "ideal ventilation". However algorithms used to achieve these ideal targets are different among different commercialized devices and the relative efficacy from an algorithm compared to another remains unknown. The main objective is this study is to compare two commercialized NIPPV that have this option

Primary Outcome Measures:
  • Mean Nocturnal transcutaneous CO2 pressure (Mean nocturnal PtCO2) [ Time Frame: 1 night ] [ Designated as safety issue: No ]
    transcutaneous CO2 pressure is measured overnight. It is a reliable estimation of arterial PaCO2 to monitor nocturnal ventilation in adults with chronic respiratory failure.

Secondary Outcome Measures:
  • Mean transcutaneous CO2 pressure during REM Sleep [ Time Frame: 1 Night ] [ Designated as safety issue: No ]
  • Mean nocturnal SpO2 [ Time Frame: 1 night ] [ Designated as safety issue: No ]
  • Awake arterial PaCO2 after 1 hour of NIPPV withdrawal [ Time Frame: After 1 night ] [ Designated as safety issue: No ]
  • Micro-arousals/hour of sleep [ Time Frame: 1 night ] [ Designated as safety issue: No ]
  • Sleep Quality assess by Visual analogic scale (100mm) [ Time Frame: 1 night ] [ Designated as safety issue: No ]
  • Respiratory residual events detected by NIPPV built-in softwares [ Time Frame: 1 Night ] [ Designated as safety issue: No ]
