What causes a person to die from lack of oxygen?
Brain Death. This condition, which can be caused by severe injury or lack of oxygen to the brain, involves these critical factors: coma; a permanent cessation of activity in the brain and brainstem, the cause of which is known and for which there are no other explanations; and no ability to generate a breath.
Can a patient be awakened?
