  1. Coefficient values are presented as medians (with 25th and 75th percentiles). R2 = 0.306. CI, confidence interval; Dx, diagnostic group; ICU, intensive care unit; PaO2/FiO2, partial pressure of oxygen in arterial blood/fraction of inspired oxygen; PiCCO, pulse contour cardiac output; R, reason for catheter insertion; RRT, renal replacement therapy; SAPS II, simplified acute physiology score.
