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

With the birth of Mechanical Ventilation in the 1950s came the ventilation induced lung injuries (VILI). Numerous works have since then shown the benefit of "protective ventilation", notably by controlling the delivered tidal volume and pressures. However, as the respiratory condition improves and the weaning is started by shifting to Pressure Support Ventilation (PSV), these parameters stop being tightly controlled. This study aims to determine whether there is a relationship between the driving pressure measured in PSV and the weaning time.
