There's no cerebral activity whatsoever. Nothing. Nada. Zip. Her brain is not receiving oxygen. It is decomposing. She is not in a coma. She is not "brain injured". She is not "brain damaged". She is dead. Absolutely and unequivocally dead.
“Her brain is not receiving oxygen.” I’m CURIOUS AS TO THE SOURCE OF HOW YOU KNOW THIS SO UNEQUIVOCALLY.
If her heart and lungs are working, I have a hard time with your claim her brain is not receiving oxygen. I have no argument her brain in all examinations is dead short of her autonomic nervous system, but the fact she is breathing and her heart is pumping on their own, pretty much devoid your claim that her “brain” is not getting oxygen.
If they have, then she is indeed dead.
