How is Brain Death Different than Coma?

Can a brain dead person hear you talk?

They do not hear or feel anything, including pain. This is because the parts of the brain that feel, sense, and respond to the world no longer work. In addition, the brain can no longer tell the body to breathe. Because the brain cannot control breathing, breathing must be done by a machine, called a ventilator.

How many days a brain dead person can live?

There is very little research on just how long the body of a brain-dead person can be maintained. The discussion of brain death dates back to the 1950s in France with six patients who were kept "alive" for between two and 26 days without blood flow to the brain.

Does the heart still beat after brain death?

If brain death is confirmed, why does an individual's heart continue beating? As long as the heart has oxygen, it can continue to work. The ventilator provides enough oxygen to keep the heart beating for several hours. Without this artificial help, the heart would stop beating.

Can a brain dead person move their hands?

Many brain-dead patients have spontaneous movements such as jerking of fingers or bending of toes that can be disturbing to family members and health care professionals and even cause them to question the brain-death diagnosis.

Can brain activity come back?

No brain function exists. Brain death results from swelling in the brain; blood flow in the brain ceases and without blood to oxygenate the cells, the tissue dies. It is irreversible. Once brain tissue dies, there is nothing that can be done to heal it.

Can brain death be misdiagnosed?

Variability in the diagnosis of brain death has the potential to lead to misdiagnosis. Even in the clearest circumstances, families may have difficulty accepting a diagnosis of brain death when they see their loved one's heart still beating and feel their body warm to the touch.

Is a ventilator life support?

It is also used to support breathing during surgery. Ventilators, also known as life-support machines, won't cure an illness, but they can keep patients alive while they fight an infection or their body heals from an injury.
