Circuit resistance modeling in failing heart rotary pump support
Musil, Jan ; Pražák, Josef ; Leitermann, D.
The stepwise resistance increase caused by the throttle valve usage in the mock-line circuit comprising the pulsating ventricle in failing heart modus and supported by rotary pump set up in parallel was studied. It appears thus important to regulate support system producing a continuous type of flow to such a regime not allowing the pulsating flow of the failing heart to disappear and preventing the mean systemic pressure value before substantial increase.
