Figure 1.
All pediatric acute respiratory distress syndrome (PARDS) positive end-expiratory pressure (PEEP)/FiO2 combinations. Actual PEEP values as a function of actual FiO2 levels (median [bar] and interquartile range [box]) for all patients with PARDS for the first day of mechanical ventilation after PARDS diagnosis. The superimposed line represents the ARDS Network protocol target combinations of PEEP/FiO2. In general, clinicians used more PEEP than recommended when FiO2 was less than 0.4 and used less PEEP than recommended when FiO2 was more than 0.5. Median PEEP level did not exceed 10 cm H2O, regardless of FiO2.
