Implication

Questions quarter-wave estimates for arterial reflection sites; leaves open validation of tube models in hemodynamics.

Key Points

The study aims to develop a reliable method to determine the effective length of the systemic arterial tree in dogs.
Measured aortic pressure, flow, and radius in seven dogs during steady state.
Used a model of arterial system as a uniform elastic tube to estimate load parameters, inertance, and compliance.
Calculated tube length from estimates of inertance and inner aortic radius.
Model fit was good, correlating well with values reported in literature.
Quarter-wave formula was confirmed to overestimate the distance to the effective reflection site.

Burattini et al. (1988) studied this question. Equivalent tube model vs. Quarter-wave formula was evaluated on Effective length of the arterial circulation (distance to effective reflection site). An equivalent tube model of systemic input impedance demonstrated that the traditionally used quarter-wave formula significantly overestimates the effective length of the arterial circulation.
