Predictors and Outcome of Early-Onset Pneumonia After Out-of-Hospital Cardiac Arrest

P_aO2/F_IO2, leukocyte count, and C-reactive protein during the first 10 days after out-of-hospital cardiac arrest, in subjects with or without early-onset pneumonia. For P_aO2/F_IO2 there were significant differences on day 4 (P = .009), day 5 (P = .003), and day 6 (P = .03). For leukocyte count there were no significant differences. For C-reactive protein there were significant differences on day 3 (P = .006), day 4 (P = .052), and day 7 (P = .02).
