The brain stem also relays information to and from the brain to the rest of the body, so it plays an important role in the brain’s core functions, such as consciousness, awareness and movement.Īfter brain death, it's not possible for someone to be conscious. The brain stem is responsible for regulating most of the body's automatic functions that are essential for life. The brain stem is the lower part of the brain that's connected to the spinal cord (part of the central nervous system in the spinal column). To save a person's family and friends from unnecessary suffering, once there's clear evidence that brain death has occurred, the person will be disconnected from the ventilator. Once the brain stem has permanently stopped functioning, there's no way of reversing it and the heart will eventually stop beating, even if a ventilator continues to be used. However, that person won't ever regain consciousness or start breathing again. This can be done by keeping a person on a ventilator, which allows the body and heart to continue to get oxygen. The lack of oxygen, which happened when the blood stopped flowing, caused the brain stem to stop working permanently.Ĭonfirming death is now more complex, because it's possible to keep the heart beating after the brain stem has permanently stopped functioning. Death was said to occur when the heart stopped beating, breathing stopped and a person stopped responding. Confirming deathĬonfirming death used to be less complicated. A person is confirmed as being dead when the brain stem stops working. If the brain stem stops working, the person will never be able to be conscious or breathe without a machine (ventilator). ![]() Brain stem death happens when the brain stem (a part of the brain) no longer works.
