Fig. 2

Absolute CO measurement and trending accuracy of the Retia Argos device and Edwards Vigileo-FloTrac device, each against reference pulmonary artery catheter (PAC)-thermodilution. A Bland–Altman plots of the CO values (N = 572 measurements from M = 58 patients). RMSE is root-mean-squared-error. B Concordance plots of intervention-induced CO changes (ΔCO = 100⋅(COafter—CObefore)/CObefore; N = 509 measurements from M = 58 patients). C Bland–Altman plots of the ΔCO values (N = 509 measurements from M = 58 patients.) The left plots in A and B match those in reference [14]
