Just out of curiosity - would one (say like a soldier) be able to effectively 'pre-emptively' wear a device in a backpack which has a permanent-ish lead to the circulatory system which does multiple things:
Provides a constant flow of oxygenated blood which allows for higher endurance, longer "holding of breath", and in the case of severe injury, oxygenated blood circulation to prevent death (unless there is catastrophic blood loss which moots the machine's ability)....
Recall all the famous designs of Cyborgs [and The Borg] with the tubes running into their face/head/nose - the tubes could be pumping externally oxygenated blood to the vitals which would suffer most in catastrophic physical unplanned destruction events.
It’s not practical. Patients on ECMO require anticoagulation, as do patients on cardiopulmonary bypass. This is a problem common to all systems which expose blood to foreign surfaces and pass it through pumps. Your hypothetical anticoagulated soldier with such a pump would bleed out lickety-split were they to suffer as much as a minor cut.
Also, such a system would likely require giant cannulae placed in rather inconvenient places, e.g., the neck, thigh, or chest, as in ECMO. That would limit movement significantly.
Peter F Hamilton's "Fallen Dragon" had a sub-plot along these lines. Some soldiers wore exo-suits-of-muscle that had access to valves embedded in the femoral and carotid arteries. The human inside was breathing for both themselves and the suit while hooked up. The suits could be disconnected and hooked up to a external rack that did circulation and respiration when not in use.
Where would the oxygenated blood come from? How much would the soldier have to carry? How do you protect this mechanism so that it's not also damaged in whatever unplanned destruction event broke the soldier?
Had. The article is from 2011; according to Wikipedia "On March 24, 2012, Cheney underwent a heart transplant procedure", "he remained alive without a pulse for nearly fifteen months." source: https://en.wikipedia.org/wiki/Dick_Cheney#Health_problems
I am convinced that Cheney is the reason Barnaby Jack was murdered.
Jack knew how to remotely attack pacemakers, as well as pumps and other medical devices and was to speak at BlackHat... but was neutralized just days prior...
