Unfortunately, the lung tissue will disagree. Strongly. It doesn't disagree with
liquid fluorocarbon as violently, but it's density is twice that of water,
and, as I mentioned, it's suspected to be immunosuppressive. Might make
sense in an emergency situation, but is not something you'd subject a healthy
volunteer to.

dangers and stresses to your system, putting a person in artificial coma
would seem to put you into the "red" zone, as stresses cumulate.

Whatever happened to space travel a la "2001"?
