NCT00603096

Brief Summary

The aim of this randomized controlled trial is comparing the improvement of diurnal PaCO2 in OHS patients after one month of NIV treatment depending upon the tools used for adjusting settings. In one arm settings will be adjusted using only nocturnal oxygen SaO2 and PaCO2 at awakening whereas in the other arm patients will benefit from a complete polysomnography under NIV.
