End-diastolic volume indices determined by transpulmonary thermodilution(TDCOtp) and pulmonary artery thermodilution may give a better estimate of left ventricular preload than pulmonary capillary wedge pressure monitoring(PCWP) and central venous press(CVP). The PiCCO system (Pulse Contour Cardiac Output system; Pulsion Medical Systems, Munich, Germany) a newly available system, uses integrated transpulmonary thermodilution to measure the volumetric preload parameter global end-diastolic volume index (GEDVI) and includes the total volumes of cardiac atria and ventricles as well as part of the systemic vascular blood volume. Compared with conventional pressure-derived preload assessment, volumetric preload determination by the PiCCO system has been shown to better reflect left ventricular filling. The PiCCO system provides intermittent cardiac output(CO) assessment by TDCOtp, continuous CO measurement by pulse contour analysis (PCCO), and an estimation of intrathoracic blood volume (ITBV) from GEDV only by transpulmonary single indicator dilution, which should be a valuable parameter of cardiac preload.展开更多
