(HealthDay News) — Doing CPR on someone in cardiac arrest can double the chances of survival, the American Heart Association says.
The AARP recommends these steps for administering CPR:

• • Do not wait. A person’s chances for survival fall up to 10 percent for every minute of delay.
  • Send someone to look for an Automated External Defibrillator.
  • Push up to two inches downward into the body.
  • Push faster. If compressions are faster, they are more likely to be more effective.
