How long does it take a brain dead person to die?

Can someone in a vegetative state hear you?

Other studies have shown that up to 20 percent of patients in various vegetative states can hear and respond on at least some level. But at least some of the responses seen could be dismissed as simple reflexes, or at best akin to someone in a dream state responding to stimuli.

Can someone with no brain activity breathe on their own?

Does your heart still beat when you’re brain dead?

The heart is part of the autonomic nervous system and thus has the ability to beat independently of the brain as long as it has oxygen. The heart will eventually stop beating as all bodily systems begin to stop working shortly after brain death. Once this process has begun, it cannot be reversed.

How long can you live after life support is removed?
