I think the primary issue with this (using my limited internet knowledge) is that most cardiopulmonary bypass leads to hemolysis, which kinda defeats the purpose of CPB. Additionally, there’s the issue of how to distribute the bypassed blood. To effectively reintegrate the blood, you’d either have to have an open “wound” in the chest or permanently installed synthetic transplants, both of which have their own issues. Additionally, you’d probably need anesthesia regardless of the method, which then relegates the point of doing all this as you’d need a functioning being not under the effects of the liquid/bypass to manage the anesthesia.
