Bland-Altmann plot of absolute cardiac output data determined by intermittent pulmonary arterial thermodilution (IPATD-CO) and autocalibrated pressure waveform analysis with the Flowtrac/Vigileo^®-system (FTV-CO) throughout the study. Closed circles = after induction; open circles = after sternotomy; closed squares = graft preparation 1; open squares = graft preparation 2; open stars = graft preparation 3; closed stars = graft preparation 4; closed triangles = graft preparation 5.
