Accuracy of Cardiac Output by Nine Different Pulse Contour Algorithms in Cardiac Surgery Patients: A Comparison with Transpulmonary Thermodilution

Figure 2

Four-Quadrant Concordance Plots. Percentage changes in cardiac output measured by transpulmonary thermodilution () and cardiac output measured by nine different pulse contour algorithms () before and after cardiopulmonary bypass (CPB). Changes below 15% (gray rectangle) were excluded from analysis.
