The first link in the Chain of Survival is the emergency care call.

When SCA strikes, an immediate 911 call is crucial; a delay of just a few minutes could prove fatal. By quickly recognizing a medical emergency, a bystander can help save a life.

Could you recognize the symptoms of SCA?

Unresponsiveness

Loss of consciousness

Lack of pulse

Cessation of breathing

SCA is not the same as a heart attack. However, a victim of either condition requires an immediate 911 call.

Your Part in the 911 Call
When fielding a 911 call, the emergency medical services (EMS) dispatcher may ask the caller questions such as these (provided by the American Heart Association):

"What is your emergency?"
To answer this question, describe the situation as extensively as possible, with such replies as "A customer had sudden chest pain and has now collapsed." Or "They've lost consciousness and they don't seem to be breathing."

"What's happening now?"
Respond: "My friend is giving CPR. We have an automated external defibrillator (AED)." Or, "We're trying to find a medically trained person to assist us."

"Where is the victim located?"
Respond: "We are at the Evergreen Company, here at 1234 Fifth Avenue NE, in the back hall."

"What number are you calling from?"
Respond: "The number is 978-555-1313."

The dispatcher may give directions such as "Stay on the line until I tell you to hang up. Rescuers are being sent to your location. Please meet them and direct them to the scene." Some dispatchers can provide medical care instructions, such as for CPR and the defibrillation process, over the phone.

A prompt 911 call sets the Chain of Survival in motion, giving the next two links, CPR and early defibrillation, the greatest opportunity for success.
