From: Arterial hyperoxia and in-hospital mortality after resuscitation from cardiac arrest
Odds ratios for hospital mortality by deciles of PaO 2 . Odds ratios for hospital mortality with partial pressure of arterial oxygen (PaO2) divided into deciles and referenced against the fourth decile (PaO2, 83 to 93). The adjusted model included the following covariates: fraction of inspired oxygen (deciles), Acute Physiology and Chronic Health Evaluation III (APACHE III) index of illness severity in which the oxygen component of the APACHE III scoring system was removed, year of admission, treatment limitation on admission to intensive care unit, patient's lowest glucose level in the first 24 hours, hospital characteristics, patient indigenous status and hospital source from home. 95% CI, 95% confidence interval.
