CPR. I was talking to Sheena a while back and realized that not everyone knows what that is. Makes sense, considering that we're all from different worlds, different times, so it's not something every world has necessarily discovered yet. It stands for cardiopulmonary resuscitation, and it's a non-magical life-saving technique that can be used in the event that someone's heart stops beating.

( Tl;dr; CPR 101 )
