Instrumental Respiratory Physiotherapy in Difficult-to-wean ICU Patients

Patients randomized to this group will receive 3 sessions per day of intensive early respiratory physiotherapy with instrumental techniques from randomization to day 7, before and after any extubation. The strategy will be applied until day 7 of randomization, regardless of the patient's status (intubated or not).

Patients in this group will receive standardized and protocolized respiratory physiotherapy to reproduce the usual practices of non-expert centers,1 to 2 sessions of manual respiratory physiotherapy (not assisted by an instrumental technique) per day until the day of successful extubation, or until day 7 if necessary
