Open Access Abstract Introduction There is limited clinical experience with the singleindicator transpulmonary thermodilution pulse contour cardiac output or PiCCO technique in critically ill medical patients particularly in those with acute heart failure AHF . Therefore we compared the cardiac function of patients with AHF or sepsis using the pulmonary artery catheter PAC and the PiCCO technology. Methods This retrospective observational study was conducted in the medical intensive care unit of a university hospital. Twelve patients with AHF and nine patients with severe sepsis or septic shock had four simultaneous hemodynamic measurements by PAC and PiCCO during a 24-hour observation period. Comparisons between groups were made with the use of the Mann-Whitney U test. Including all measurements correlations between data pairs were established using linear regression
