  2. Give 30 chest compressions: push firmly downwards in the middle of the chest around 5-6cm and then release.

What is an Automated External Defibrillator (AED)?

An AED is a portable machine that can shock the heart back into normal rhythm. You can find them in many public places, such as train stations, shopping centres or schools.

Helping someone who is unresponsive and not breathing when an AED is available

  1. Check for breathing by looking, listening, and feeling for breaths.
    - Tilt their head back and lift their chin to open their airway. Look at their chest or stomach to see if it is moving, listen and feel for normal breaths on your cheek.
    - If they are not breathing normally you will not see, hear, or feel signs of normal breathing.
  2. Call 999 immediately or ask someone else to do it. Ask someone to get the AED.
  3. Give cycles of 30 chest compressions and two rescue breaths.
    - To give chest compressions push firmly downwards in the middle of their chest and then release.
    - To give rescue breaths tilt their head back, seal your mouth over their mouth and pinch their nose. Blow steadily.
  4. Ask a helper to open the AED, turn it on if necessary and follow all its voice prompts.
    - Continue to give chest compressions and rescue breaths.
    - Try to minimise any interruptions to chest compressions.
    - The AED will give step by step instructions.
