Extubation stay at high risk of reintubation even scheduled and in the best condition of hematosis. Re-intubation's rate in main studies in chronic obstructive diseases reach to 20% and it is associated to a higher mortality, higher pneumonia under mechanic ventilation, and higher duration of hospitalization especially in intensive care units.
Place of NIV in this situation is still on evaluation. A recent meta-analysis demonstrates that use of NIV in post-extubation in COPD seems to decrease re-intubation rate.
HFO, thanks to its properties (oxygen, humidification and heat with high flow) could be useful in this population in ventilatory weaning. Compared to oxygen conventional therapy with high-concentration mask, HFO seems to be as efficient and better tolerated. A recent study shows that HFO is non-inferior to NVI in post-extubation in patient with high risk of re-intubation.
Furthermore, oxygenation in post-extubation should be optimized to avoid hypoxemia and hypercapnia in this patient at risk of hypoventilation. Place of AFOT could improve hematosis by providing adapted flow of oxygen to each patient.
The investigator choose the hypothesis for this study that HFO is as effective and tolerated in post-extubation than NIV with AFOT.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| High Flow Oxygen (HFO) | Experimental | HFO is a mix tap of air and oxygen. It permits to control FiO2 and generated controlled high flow air until 60/min. Air and oxygen are mixed, warmed, humidified and issued to patient by a warming monopod inspiratory circuit to nasal cannulas of a large diameter. Expiration is free. |
|
| Non Invasive Ventilation (NIV) | Active Comparator | NIV was already evaluated in post-extubation. This technic is now used in daily consolidation processing after extubation because it provides a ventilator help with two levels of pressure helping in respiratory work. Adding Automated Flow Oxygen Titration could optimized patient's oxygenation and reduce workload of caregivers |

| Dyspnea scale of Borg | Dyspnea score which is a quantitative measure of the perception of effort during a physical exercise. The measure is a rating on a scale from 0 to 10 attached to different words of appreciation: "very light, difficult, painful ..." effort. This global measurement, based on the physical and psychological sensations of the person, takes into account the physical condition, the environmental conditions and the level of general fatigue. The scale between 0 and 10 was designed to approximate the heart rate of a healthy young adult (effort 8 represents 80% of the CF). |
