Hybrid E-H windkessel model improves mock circulatory flexibility; leaves open validation before assist-device or training use.
The development of a hybrid electro-hydraulic impedance simulator provides a flexible and potentially cost-effective model for testing mechanical assist devices such as LVADs.
Kozarski et al. (2003) studied this question. Electro-hydraulic (E-H) impedance simulator was evaluated on Characterisation of the E-H impedance simulator and its behaviour when connected to a hybrid ventricular model. An electro-hydraulic impedance simulator successfully represented the input impedance of the systemic arterial tree under different hemodynamic conditions, including with a left ventricular assist device.
