Effect of a Personalized Weaning Strategy on Weaning Success

Weaning strategy in accordance with the care practices of the department, regarding the assessment of weaning criteria, SBT and extubation modalities.

"\- Risk factors of WIPO~Step 1 : Daily assessment of weaning criteria in accordance with the study protocol.~Step 2 : Spontaneous breathing trial with T-piece for an hour. Measure of protein and haemoglobin by blood sample before and after the trial.~Step 3 : Reconnect the patient to the ventilator for at least 30 minutes and then extubate if SBT is successful.~If SBT failed : no extubation and new SBT the next day. Optimization of cardiac function or fluid overload will be in charge of the investigator.~\- No risk factors of WIPO~Step 1 : Daily assessment of weaning criteria in accordance with the study protocol.~Step 2 : Spontaneous breathing trial with pressure support ventilation (pressure support from 5 to 8 cmH20 - PEEP at 0 cmH20) for an hour.~Step 3 : Reconnect the patient to the ventilator for at least 30 minutes and then extubate if SBT is successful."
