a The Bland-Altman analysis for cardiac index measurements with bioreactance-based Starling SV 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 2. b The trending ability of Starling SV evaluated with four-quadrant plot at all measurement points. The changes in consecutive cardiac index measured with Starling SV (ΔCIStarling) and the bolus thermodilution technique (ΔCIPAC) are plotted against each other
