Figure 1

Bland-Altman plots for the absolute values of pulse pressure-derived cardiac output (PPCO) versus esophageal Doppler cardiac output (EDCO). Agreement between PPCO and EDCO measurements according to Bland-Altman analysis is shown. Only one marker for subject is represented in the graph. The marker size is relative to the number of observations per subject. Solid lines represent bias (mean difference between EDCO and PPCO measurements). Dashed lines are the upper and lower limits of agreement: bias ± 1.96 standard deviation (SD).
