Systematic review and meta-analysis evaluates the mortality predictive value of the PaO2/FIO2 ratio in acute respiratory distress syndrome, highlighting its clinical utility for risk assessment.
Objective Despite the controversy regarding its clinical utility, the arterial oxygen partial pressure (PaO2) to the fraction of inspired oxygen (FIO2) ratio has been used to define the severity of acute respiratory distress syndrome (ARDS). This systematic review and meta-analysis (SRMA) details summary estimates of the predictive performance of PaO2/FIO2 ratio in predicting mortality in patients with ARDS.
