The main objective of the study is to assess the FreeDom innovative strategy (FreeO2 at Domicile) to reduce hospitalization duration in patients with COPD exacerbation. This strategy will enable an early return home, patients using an innovative device that automatically adjusts and wean the oxygen flow (FreeO2 system) coupled to telemedicine and tele-rehabilitation.~The main hypothesis of this study is that a strategy for an early return home with a home hospitalization managed by telemedicine will reduce the length of hospitalization by 50 percent from 30 days.
The main objective of the study is to assess the FreeDom innovative strategy (FreeO2 at Domicile) to reduce hospitalization duration in patients with COPD exacerbation. This strategy associates early hospital discharge, automated O2 flow weaning with FreeO2 system, telemedicine and tele-rehabilitation.~The main hypothesis of this study is that the FreeDom strategy will reduce the number of hospitalization day by 50 percent at day 30.
