Conventionally, investigators fit reduced arterial system models to data, and the resulting model parameters represent putative arterial properties. The Windkessel applies to low frequencies, and the ILT applies to high frequencies.
Intermediate frequencies are sensitive to arterial system topology.
The current work uses the Windkessel and the ILT provide a novel means to quantify the frequencies that C tot , Z o , and arterial topology determine a particular measured pressure-flow relationship. Furthermore, this approach allows quantification of how spatial topology and site of reflection effect pressure and flow without assuming a particular arterial system model.
