Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In mechanically ventilated patients the PaO2/FiO2 ratio might not be the best reflection of the severity of ARDS. It does not incorporate variables and settings used during mechanical ventilatory support such as the positive end expiratory pressure (PEEP), inspiratory time to expiratory time ratio (Ti:Te), and the peak alveolar pressure (Palv). The aim is to identify a new oxygenation index for stratification of severity of ARDS
