Jahi McMath was a thirteen-year-old girl who was declared brain dead in California following surgery in 2013. This led to a bioethical debate engendered by her family's rejection of the medicolegal findings of death in the case, and their efforts to maintain her body using mechanical ventilation and other measures. Her parents considered these measures to constitute life support, while her doctors considered this to be futile treatment of a deceased person. The family also claims that the hospital pressured them to donate McMath's organs. What will be true for ‘brain dead’ cases?
I: In brain death there is no chance of recovery because body of a brain dead person is unable to survive without artificial life support.
II.The difference between brain death and a vegetative state is that it's possible to recover from a vegetative state, but brain death is permanent.
III. After brain death, it may be possible for the person's organs to be used in transplants.
