Figure 1

Cardiac output and mean arterial pressure during the study period. The time course of (a) cardiac output (CO) determined by intermittent pulmonary arterial thermodilution (filled circles = IPATD-CO) and autocalibrated pressure waveform analysis with the FlowTrac/Vigileo® system (filled squares = FTV-CO) and (b) mean arterial pressure (MAP) in patients undergoing coronary artery bypass grafting surgery before cardiopulmonary bypass subjected to variations in arterial blood pressure either by the surgical stimulation or noradrenaline infusion. * significant difference (P < 0.05) in comparison with the previous time point (Student's t-test with Bonferoni-correction). § significant difference between IPATD-CO and FRV-CO (analysis of variance) AI = after induction; AS = after sternotomy; GP = graft preparation. CABG =; CI = confidence interval; CO = cardiac output; FTV = Flowtrac-Vigileo®; GP = graft preparation; IPATD = intermittent pulmonary arterial thermodilution; ICU = intensive care unit; MAP = mean arterial blood pressure.
