what declares a person brain dead
A brain-dead person also cannot maintain his or her own body temperature, so the body is kept warm with blankets, a high room temperature and, sometimes, warm IV fluids, Greene-Chandos said. The body of a brain-dead person is usually not supported for very long, Greene-Chandos said. Doctors sometimes provide support (in the form of a ventilator, hormones, fluids, etc.) for several days if the organs will be used for donation, or if the family needs more time to say good-bye, Greene-Chandos said.
