Open Access Abstract Introduction The reliability of autocalibrated pressure waveform analysis by the FloTrac-Vigileo FTV system for the determination of cardiac output in comparison with intermittent pulmonary arterial thermodilution lPATD is controversial. The present prospective comparison study was designed to determine the effects of variations in arterial blood pressure on the reliability of the FTV system in patients undergoing coronary artery bypass grafting CABG . Methods Comparative measurements of cardiac output by FTV derived from a femoral arterial line software version and IPATD were performed in 16 patients undergoing elective CABG in the period before institution of cardiopulmonary bypass. Measurements were performed after induction
