Comparison of the OI and PaO ₂ /FiO ₂ score in evaluating PARDS requiring mechanical ventilation

To examine the differences between oxygenation index (OI) and arterial partial pressure of oxygen to the fraction of inspired oxygen (PaO2 /FiO2 , [P/F]) in evaluating the severity of pediatric acute respiratory distress syndrome (PARDS).The severity of PARDS was graded by using the OI score and P/F ratio, respectively. The data including clinical indexes and prognosis indicators were recorded and analyzed.During the 3-year study period, there...
