About this trial
Specific characteristics of the lung, such as its functional capacity, heterogeneity, and recruitment potential, can influence the development of ventilator-induced lung injury even under safe ventilation conditions. Objective: To evaluate the risk of ventilator-induced lung injury at the regional level in patients with acute respiratory distress syndrome ventilated with similar tidal volumes and inspiratory pressures.
