[|Human|] Husband had a heart attack. Drs. say he had very little oxygen at arrival. He was placed under sedation, however they suspended the sedatives and he doesnt respond to commands . he is on a respitator, how long for us to know if he has brain damage or not.
[|AI|]  Hello madam, I pray to God for you. There are some hallmark signs of brain death-1)when you shine torchlight in the eyes, the pupils don't constrict or react, and they remain fixed and dilated.2)when you touch the cornea of eye with a wisp of cotton, eyes don't blink in a dead brain.3)when you turn the head towards one side, in normal individuals eyeball move in opposite direction(dolls eye reflex). In a dead brain,eyeballs remain fixed. These signs suffice for calling it a brain death, for all practical purposes.
