CPR is the one core skill that is readily accessible to most people but few take the time to learn it. Knowing basic CPR can mean the difference between life and death for a loved one – given that over 80 percent of all out-of-hospital emergencies requiring CPR (i.e., cardiac arrest, drowning and choking) occur in private residential settings. The most likely victim of sudden cardiac arrest will be a student’s parent, grandparent or sibling.
