a The Bland-Altman analysis for cardiac index measurements with pulse power device LiDCOrapid and the bolus thermodilution technique with a pulmonary catheter, all measurement points. The bias and LOA with 95% CIs are shown with lines. Exact numbers are seen in Table 3. b The trending ability of LiDCOrapid evaluated with four-quadrant plot at all measurement points. The changes in consecutive cardiac index measured with LiDCOrapid (ΔCILidcorapid) and the bolus thermodilution technique (ΔCIPAC) are plotted against each other
