How long can a brain dead person survive on a ventilator?
Today, with ventilators, blood-pressure augmentation and hormones, the body of a brain-dead person could, in theory, be kept functioning for a long time, perhaps indefinitely, Greene-Chandos said.
How long does vegetative state last after TBI?
Most people who remain in a vegetative state die within 6 months of the original brain damage. Most of the others live about 2 to 5 years. The cause of death is often a respiratory or urinary tract infection or severe malfunction (failure) of several organs. But death may occur suddenly, and the cause may be unknown.
What is the prognosis of brain death?
Prognosis for Brain Death The diagnosis of brain death is equivalent to the person’s death. No further treatment can prevent death. After brain death is confirmed, all supporting cardiac and respiratory treatments are ended. Cessation of ventilatory support results in terminal arrhythmias.
Are people in PVS legally brain dead?
While brainstem death can be diagnosed clinically, accurate prognosis in PVS requires additional investigation. Brain death is equivalent to death, while PVS is not; management of the latter is more complex because of medical, social, ethical and legal factors.
What is the longest time a brain dead person has been on life support?
Several years ago, the autopsy report of a totally brain-dead patient named TK who was kept on life support for nearly twenty years was published in the Journal of Child Neurology. He remains the individual kept on life support the longest after suffering total brain failure.
What are the odds of coming out of a vegetative state?
Generally, adults have about a 50 percent chance and children a 60 percent chance of recovering consciousness from VS/UWS within the first 6 months in the case of traumatic brain injury. For non-traumatic injuries such as strokes, the recovery rate falls within the first year.
What is the difference between brain dead and vegetative state?
Brain death: Irreversible cessation of all functions of the entire brain, including the brain stem. A person who is brain dead is dead, with no chance of revival. Vegetative state: The person has depressed consciousness, brain stem function and can breathe without support.
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.
What is the difference between a vegetative state and brain dead?
The difference between brain death and a vegetative state, which can happen after extensive brain damage, is that it’s possible to recover from a vegetative state, but brain death is permanent. Someone in a vegetative state still has a functioning brain stem, which means: some form of consciousness may exist.
Will you wake from a vegetative state?
Patients in a vegetative state may have awoken from a coma , but still have not regained awareness. In the vegetative state patients can open their eyelids occasionally and demonstrate sleep-wake cycles, but completely lack cognitive function. The vegetative state is also called a coma vigil.

Is recovery from brain death possible?
Unfortunately, there is absolutely no recovery from brain death. Once blood stops flowing to the brain (the definition of brain death), the neurons in the brain die. There is no potential of recovery once this happens.
Are persons in the ‘vegetative’ state dying?
Most people who remain in a vegetative state die within 6 months of the original brain damage. Most of the others live about 2 to 5 years. The cause of death is often a respiratory or urinary tract infection or severe malfunction (failure) of several organs.
Does a person in vegetative state feel pain?
People in a vegetative state may feel pain . IT IS a nightmare situation. A person diagnosed as being in a vegetative state has an operation without anaesthetic because they cannot feel pain.
