Driving Pressure as a Predictor of Mechanical Ventilation Weaning Time on Post-ARDS Patients in Pressure Support Ventilation.

"* Daily measures of End Inspiratory Pressure with respiratory synchronisation optimised by use of EAdi~* Daily spontaneous breathing trial using low levels of pressure support~* Pplat, Respiratory System Compliance, Driving Pressure, PEEP, Tidal Volume will be monitored daily as well as clinical and other routine ventilatory data. Data concerning initial severity of ARDS, and duration of ARDS, controlled mechanical ventilation, sedation and neuromuscular blockade and date of first spontaneous breathing trial will be collected. A weaning test will be conducted daily."
