How many days a brain dead person can live?
(Previously, a person was considered dead only when their heartbeat and breathing stopped.) 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.

What happens to the brain when you die?
In brain death, the brain of a patient has irreversibly lost all its functions, whereas the rest of the organism is still working, thanks to a ventilator or another mechanism that replaces the patient’s brain stem in providing the necessary stimulation of lungs, heart and intestines.
How do you make a brain death diagnosis?
To help clinicians make a brain death diagnosis, The Johns Hopkins Hospital in June 2016 created a Determination of Death by Neurological Criteria Support Team. Here’s how it works: A patient arrives in the emergency room after an overdose, car accident or other trauma that caused extensive brain injury.

What are the challenges of defining and diagnosing brain death?
The Challenges of Defining and Diagnosing Brain Death. The neurological examination must be repeated at least once after a minimum interval of six hours, to ensure that brain function is not temporarily suppressed by factors such as high doses of narcotics or intense cold.
