Differences in ventilator strategy on Day 1 of acute respiratory distress syndrome (ARDS) between Children’s Hospital of Philadelphia (CHOP) and Children’s Hospital Los Angeles (CHLA), stratified by PaO2/FiO2 (PF) ratio 24 hours after pediatric ARDS (PARDS) diagnosis. All variables are scaled to a maximum value of 1 for each variable, to highlight relative differences between datasets. Actual values for these parameters can be found in Tables 4 and E4. The individual squares and diamonds represent the median value for the dataset for a given variable. (A) For all patients, CHOP generally used a higher mean airway pressure (PAW), higher positive end-expiratory pressure (PEEP), and slightly lower FiO2 than CHLA, with slightly higher PF ratio and oxygenation index (OI), and similar driving pressure and Vt. (B and C) For patients with PF ratio (B) 200 to 300 or (C) 100 to 200, PAW and PEEP are higher at CHOP than CHLA. (D) For those with PF less than or equal to 100, PAW, PEEP, OI, and PF ratio are similar between datasets, although FiO2, Vt, and driving pressure are slightly higher at CHOP.
