    Thank you! I can reproduce some helpful variations with respiration, and the AV dissociation trick with V pacing works perfectly.

    I’m trying to simulate greater variations in intrathoracic pressure during respiration, to demonstrate clear changes on transvalvular mitral flow and AO pulse pressure, but even at Tidal Volume maxed to 1000cc, the pressure variation is relatively small. How might I increase the amplitude of the change? Is there an airway resistance parameter I can change? Thanks again. Terry

    I would love to try varying intrathoracic pressure, but I do not see an Anesthesia input panel on my version. Where can I find that one? I have 20 other ones that I looked over. Thanks!

    Appreciate the response. However i wanted to model PERIcardial constraint such as a constrictive,calcified pericardium. In a circuit-based model like Harvi, I am not certain how to do that. A hyperbolic decrease in pericardial compliance when total cardiac volume passes a set threshold seems needed. Happy to collaborate on implementation if that would be helpful.

    What parameter changes might best simulate pericardial constriction? And can respiration be added that alter intra-thoracic pressure?
