Comparison of theoretical results (red solid line) with the results in-vitro experiments (black dots), in which the measured \(\Delta t_{central}\) is plotted as function of the value of the relative resistance R of the catheter with respect to its standard value \(R_0\), in which \(\Delta t_{central}\) is defined as the measured or calculated value of \(t_{central}\) with respect to the standard value of \(t_{central}\) as calculated for \(R_0\). Solid green line Linear regression line. Pearson’s R was 0.89; standard deviation between theory and experiment was 8.4 s. Dashed green lines regression line ± standard deviation
