Single logistic regression models were calculated for each hemodynamic variable and were each adjusted for age, admission year, mean catecholamine (epinephrine, norepinephrine, dobutamine and milrinone) dosages and SAPS II (excl. the systolic arterial blood pressure and heart rate count). Variables are ranked (top to bottom) according to the value of the Wald statistics. * significant association with 28 day-mortality; † 92 (77.2%) patients were monitored with a pulmonary arterial catheter.
CI = cardiac index; Con Int = confidence interval; CPI = cardiac power index; CVP = central venous blood pressure; HP = hourly portion; MAP = mean arterial blood pressure; MPAP = mean pulmonary arterial blood pressure; RR = relative risk; SAPS II = Simplified Acute Physiology Score II (excl. heart rate and systolic arterial blood pressure counts); SvO2 = mixed venous oxygen saturation; SVRI = systemic vascular resistance index.
