Open Access Abstract Introduction Adequate fluid loading is the first step of hemodynamic optimization in cardiac patients undergoing surgery. Neither a clinical approach alone nor conventional parameters like central venous pressure CVP and pulmonary capillary wedge pressure PCWP are thought to be sufficient for recognizing fluid deficiency or overload. The aim of this study was to evaluate the suitability of CVP PCWP global end-diastolic volume index GEDVI pulse pressure variation PPV and stroke volume variation SVV for predicting changes in the cardiac index CI and stroke volume index SVI after sternotomy. Methods In 40 patients CVP PCWP GEDVI PPV SVV and the CI were measured at two points of time. One measurement was performed .
