In conclusion, this preliminary study showed in real life conditions, the possibility of a systematic switch of NIV to CPAP in most stable patients with OHS and a concomitant OSA, with similar efficacy on diurnal and nocturnal alveolar gas exchange, quality of life and quality of sleep. These results need to be confirmed by a larger trial that could also evaluate the clinical consequences of this switch in the longer term, especially cardio-vascular consequences.
