Table 2.

Estimates of characteristic impedance and hemodynamic parameters under various conditions. The table lists critical frequency (f_c), HR, cardiac output (CO), mean pressure (P_mean), and pulse pressure (P_pulse). Values correspond to the hemodynamic conditions described by datasets 1–3 in Section 2.1. For comparison, pressure and flow units are converted to mmHg and cm/s for all datasets. Zc estimates listed below were also plotted, with original units, in the figures mentioned in last column.
