Table 3 Summary of tube-load models based on different assumptions

From: A review on low-dimensional physics-based models of systemic arteries: application to estimation of central aortic pressure

Model type Model feature Model parameter estimation
T-tube model Two parallel tubes signify head-end and body-end propagation paths Using frequency domain method from central and peripheral pulse waves
Lossy tube-load model Blood pressure decays along the arterial tree Using frequency domain method from central and peripheral pulse waves
Nonlinear tube-load model Arterial compliance is an exponential function of blood pressure Using time domain method from central and peripheral pulse waves
Non-uniform tube-load model Tube exponentially tapers along arterial vessels Using frequency domain method from central and peripheral pulse waves
