First objection: are you dead in a sensory deprivation chamber? How about for
prolonged periods of time? Is being in a coma the same as having died? Is
being asleep tantamount to having perished?

I'm glad that you are starting to at least use the terminology "to some degree".
Yet by "The patient survives" you're still clinging to it being an all or nothing
proposition. I prophesy that will be trouble for you.
What if 99% of your brain is temporarily frozen? What about 30% or 50%.
Don't plead too much ignorance as to the specifics of brain function: do you
really imagine that reality can be forced into "yes, he survived with 100%
fidelty" or "no, he did not survive at all"?
