Implication

Refines arterial analog models; leaves open in vivo validation before any hemodynamic applications.

Structured PICO

P
Population
Analog computer model of the human systemic circulatory system (electrical equivalents of a segment of artery)
I
Intervention
Modified electrical network accounting for the sleeve effect (interaction between viscous and inertial forces) and anomalous viscosity of blood
C
Comparator
Previous electrical equivalents lacking representation of the sleeve effect
O
Outcome
Derivation of a corrective network and modifications to the electrical circuit to represent oscillatory flow impedance

The study provides a modified electrical analog circuit that more accurately models the human arterial system by accounting for the sleeve effect and anomalous blood viscosity during pulsatile flow.
