FIGURE 2. Graphical representation of the effect of pre-ECLS PaO₂/FiO₂ ratio on the probability of fatal outcome from ELCS, derived from the multiple logistic regression model of pre-ECLS variables found to be independent predictors of outcome. The light gray box represents the 95% confidence interval for the graph.

FIGURE 1. University of Michigan algorithm for treatment of severe ARDS. PIP, plateau inspiratory pressure; PEEP, positive end-expiratory pressure; FiO₂, fraction of inspired oxygen; SaO₂, arterial oxygen saturation; SvO₂, mixed venous oxygen saturation; I:E, inspiratory to expiratory; Hct, hematocrit; PRBC's, packed red blood cells; CVVH, continuous veno-venous hemofiltration; ECLS, extracorporeal life support.
