Spike, the vascular system is not designed to be easily
interfaced with cannulas & Co. "Whack off" (<-blame Spike, not
me) the head is hence *not* a good idea.

Lifetime of a coma human on ventilator is several months,
with optimal care. You have to constantly battle respiratory
infections, because you don't get bronchial secret out of
your system in a natural (cough, cough) way.
(Btw, inserting the gastric tube is best done once. And
you better check that the end is indeed where you think it
is, or very bad things will start happening).
Then there are bed sores. Atrophy. Etc. So it doesn't work
as you think you would. Keeping apneic comatose people alive
shows the limitations of the state of the art.

Good question. Have you heard about "Mike the Headless Chicken"?
