Cardiopulmonary resuscitation (CPR) is also known as mouth-to-mouth. It's a mix of mouth-to-mouth rescue breaths and chest compressions.

A chest compression is when you apply pressure to someone's chest who is not breathing.

You do this to keep blood and oxygen flowing in the body.

Information: 

You do not have to do the mouth-to-mouth part to save a life, but you must do the compressions.

Do CPR until help arrives

Stay on the phone. The emergency call operator will guide you on what to do next.

They'll give you instructions on how to do CPR, if it's needed.

If you are doing CPR, send someone to get an automated external defibrillator (AED).

It is crucial to continue CPR until paramedics arrive.

Information: 

Even though you are still on the call, ambulance paramedics are on their way to you.
