Figure 3. (Left) Simultaneous bolus thermodilution and model-stimulated cardiac output after calibration (n = 137). Solid line = line of identity; TDCO = bolus injection thermodilution cardiac output; MCO = model-stimulated cardiac output. (Right) Differences between simultaneous TDCO and MCO after calibration plotted against their mean (n = 137). Horizontal lines = mean +/- 1.96 SD.
