Check for responsiveness
The second step is to check for responsiveness.
Checking to see if the victim is responsive. Kneel and ask, " ARE YOU OK?"
The reason is the individual may just be sleeping. Also, it is important to always ask a conscious victim for permission to help them. If they don't want your help, you can always walk away.
If there is no response, you must immediately summon an ambulance by calling 911. Recent studies have conclusively shown that victims who are not breathing and do not have a heartbeat have a substantially greater chance for survival if they receive prompt advanced medical care in a hospital or by trained paramedics.
Only after a call is placed for emergency medical services does a volunteer attempt to further help an unconscious victim.
If there are bystanders on the scene, summon someone to your side to provide assistance.
