Figure 1From: Plasma levels of surfactant protein D and KL-6 for evaluation of lung injury in critically ill mechanically ventilated patients Mechanical ventilation parameters. Mechanical ventilation parameters in patients with ALI/ARDS (circles) and without lung injury at onset of mechanical ventilation (squares). Open symbols: patients ventilated with a lung-protective mechanical ventilation strategy with lower tidal volumes; closed symbols: patients ventilated with a potentially lung-injurious strategy using conventional tidal volumes. VT, tidal volume; Pmax, maximum airway pressure.Back to article page
