1/ Most people think the heart drives circulation. But what if that’s backwards? Anderson’s model flips the whole idea of cardiac output on its head — and it changes how you think about fluid, flow, and failure. 🧵👇 #physiology #FOAMed #MedTwitter #criticalCare #cardiacOutput
I hope here is the answer to all your questions!: Starling’s law is always present - it’s just not the limiting variable until compliance starts to run out. In Phase 1, the heart is compliant and well-coupled: venous return and volume rise freely while pressure hardly changes.…
Yes - because if you replace RAP with LVEDV on the x-axis, you switch from the system view (pressure–flow) to the ventricular view (volume–flow). Even when RAP stays constant, EDV still rises as venous return increases - the ventricle accepts more volume at the same filling…
1/ After the excellent discussion a few days ago by the incredibles @NephroP @icmteaching @khaycock2 @ArgaizR , I made my humble contribution by creating these illustrative figures. Among several factors — such as lymphatic clearance efficiency, albumin , and skin compliance —…
