My Aunt suffered a major traumatic brain injury when she was struck walking across the street. A pedestrian, she was knocked down by a vehicle. She survived the resulting craniotomy and had a series of events that followed. She had two body infections with high fevers. her heart stopped in the coolng process. She probably was fighting a fever. her heart stopped and she was revived manually by chest compressions. it took 5 min before she was revived. is she brain dead?
