Have you taken our CPR/AED or First Aid class?  If so, why not sign up to possibly save a life by using the free PulsePoint mobile app?  It will alert CPR-trained bystanders if someone nearby is having a sudden cardiac arrest that may require CPR.  The app is activated at the same moment that fire and EMS resources are dispatched to the scene.  Without oxygen-rich blood, permanent brain damage or death can occur in less than 8 minutes. After 10 minutes there is little chance of successful resuscitation. The American Heart Association estimates that effective bystander CPR, provided immediately after sudden cardiac arrest, can double or triple a person’s chance of survival.  Download the free PulsePoint app, then find and follow the National City Fire Department.  Go to settings and select the “CPR” notification box.
