It's National CPR and AED Awareness Month, and doctors say that learning the basics could mean the difference between life and death. Our Ellie Janzen has the story. If you come across a person who is not breathing or does not have a pulse, would you know what to do?  The American Red Cross says immediate CPR can double or triple the chances of survival after a cardiac arrest. Before you start, call 9-1-1 to get EMS, then start with chest compression, 100 to 120 times a minute. The best way to remember that is with the rhythm of the song "Staying Alive." Mouth-to-mouth is not recommended anymore, but the sooner you act, the better.
