Comparison of the PaO2/FiO2 Ratio to Other Oxygenation Indexes for the Classification of Severity of Acute Respiratory Distress Syndrome

American University of Beirut Medical Center150 enrolled

Overview

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
