You are correct, ga medic. My niece was considered brain dead, and seven of her organs were donated. She was artificially kept alive from Friday, at 8:30 pm, until Sat. at 1pm. The reason for the time span was to get the donees prepared. And, the bill was paid by those who received her organs, not her family.
I would offer a point of clarification here. Just like in the story above where the mother makes the mistake of saying that her son "was kept alive" after brain death. It's just not quite accurate. The body isn't "alive" other than the sense that they are artificially keeping fluids flowing and organs mechanically functioning so they don't start to decompose
before they can be transplanted. But if the brain is dead, they're dead.
