CPR minimizes the possibility of brain damage by supplying
oxygen to the brain, but the heart won't start beating again
without defibrillation. The possibility of successful resuscitation
declines 7-10% with each minute that passes without defibrillation.
After 12 minutes, less than 2-5% of victims will live.
