SP is a 52-year-old male who had an out-of-hospital cardiac arrest 10 days ago. He was found by his wife unconscious on the floor after an unknown amount of time. She provided cardiopulmonary resuscitation for 15 minutes until emergency medical services arrived. The initial rhythm was fine ventricular fibrillation and a stable rhythm with pulse was obtained after 10 minutes of advanced cardiac life support. He was transported to the local tertiary care hospital and hypothermia was provided. After rewarming for 24 hours, SP had a Glasgow Coma Scale of 3 (totally unresponsive). Despite a prolonged discussion of prognosis in anoxic brain injury, the patient's wife and children advocated aggressive treatment stating ''we're expecting a miracle to happen.'' An electroencephalogram (EEG) done yesterday showed no significant brain activity. Today, the medical team performed an apnea test on SP, which showed a 20-mm Hg increase in PCO 2 , supporting a diagnosis of brain death. A follow-up radionuclide cerebral flow study confirmed the diagnosis of brain death. The palliative medicine team discussed the results of the brain death determination at length with the family, who threatened to sue the hospital if SP was taken off life support, arguing that people recover from comas and that removing him from life support would be ''tantamount to murder.'' Risk management recommended deferring any withdrawal of medical treatment. Multiple discussions with the family had the same result and an ethics consult was requested.
