Oxygenation Index, Oxygen Saturation Index vs PaO/FiO *PEEP: A Secondary Analysis of OXIVA-CARDS Study.

Background: The classification of Berlin definition is based on the PaO/FiO ratio, which has been found to have a poor association with mortality. Airway pressures reflect lung compliance and the settings of mechanical ventilators. In this study, we aimed to investigate the change in the severity of COVID-19-associated acute respiratory distress syndrome (ARDS) classification using [PaO/FiO × PEEP] (P/FP) ratio compared to the traditional P/F ratio, and whether the P/FP ratio improves the predictive validity of in-hospital mortality.
