🚨 Simulated Emergency Call – Cardiac Arrest

In this training module, we listen to a simulated 999 call from a real ambulance control centre. This simulation involves a patient in cardiac arrest and is designed to show how call handlers prioritise life-threatening incidents and provide CPR instructions over the phone.

For confidentiality reasons, we cannot show the screen, but you will hear the full conversation. The call demonstrates how the operator quickly gathers information, sends help, and gives calm, step-by-step instructions to perform chest compressions until the ambulance arrives.

đź“ž Key Elements of the Call

  • Confirming whether the patient is breathing
  • Gathering the exact address, town, and postcode
  • Organising emergency help and staying on the line
  • Checking the availability of a defibrillator (AED)
  • Giving clear CPR instructions with a guided compression rhythm

❤️ CPR Instructions from the Operator

Once cardiac arrest was confirmed, the caller was instructed to:

  1. Lay the patient flat on their back and remove anything under their head
  2. Place the heel of one hand on the breastbone, between the nipples
  3. Put the other hand on top and pump the chest hard and fast – at least twice per second and about two inches deep
  4. Follow the operator’s rhythm count ("One, two, three, four")
  5. Continue compressions without stopping until the ambulance crew arrives

The operator gave continuous reassurance and encouraged the caller to keep going. This call reinforces that early CPR and defibrillation are critical to survival and that emergency operators are trained to guide callers every step of the way.

Remember: Stay calm, follow instructions, and don’t stop CPR unless told to do so by the ambulance crew. You can help save a life.
