My understanding is that after a few minutes without oxygen, the chemistry inside your brain is "fucked up" and even if you get oxygen back it's gone, you're already a vegetable. I like to think that "the state of the machine is gone" but I'm not a doctor

I think that's the part that might get people though. Since a comatose brain is not necessarily fully gone

So I guess the question is what differentiates a comatose brain from one that is no longer capable of consciousness?
