First aid for someone who’s
unresponsive and not breathing when an AED is available

Watch the video, in which Duncan gets help. He is unresponsive and not breathing but an automated external defibrillator (AED) is available.

Use the information below to remind yourself how to help someone who is unresponsive and not breathing when an AED is available.

1

Check breathing by tilting their head backwards and looking and feeling for breaths.

When a person is unresponsive their muscles relax and their tongue can block their airway so they can no longer breathe. Tilting their head back opens the airway by pulling the tongue forward. Looking at their chest to see if it’s moving, and feeling for their breaths on your cheek, will help you tell if they’re breathing or not.

Give chest compressions.

Chest compressions help blood continue pumping around the body. This keeps vital organs, including the brain, alive. Many people call this CPR, which stands for cardio-pulmonary resuscitation.
