Study Comparing Two Ventilation Modes NAVA (Neurally Adjusted Ventilatory Assist) Mode and Spontaneous Breathing With Inspiratory Pressure Support (IPS) Mode in Consecutive Patients Hospitalized for Acute Respiratory Failure Requiring Mechanical Ventilation With Endotracheal Tube.
ZEPHYR: Multicenter, Prospective, Randomized, Open-label Study in Consecutive Patients Hospitalized for Acute Respiratory Failure Requiring Mechanical Ventilation With Endotracheal Tube. This Study Compared Two Ventilation Modes: NAVA Mode and Spontaneous Breathing With Inspiratory Pressure Support (the Latter is Considered as the Reference Ventilation Mode).

Description de la mesure |
Délai |
|---|---|---|
|
Evaluate the benefit of NAVA mode as compared to IPS mode in terms of duration of spontaneous ventilation 48 hours after inclusion.
Délai: Continuous recording during 48 hours following the intubation
|
The time spent in different modes of spontaneous ventilation (NAVA, IPS) and controlled ventilation (VAC controlled pressure) will be measured.
The primary endpoint will be the proportion of patients remaining in spontaneous ventilation after the first 48 hours.
