Faire face à un adulte qui ne réagit pas

This leaflet is created from first aid advice provided by St John Ambulance, the nation's leading first aid charity.

If someone becomes unresponsive they need someone to help keep them safe and prevent further harm. The type of help they need varies depending on why they have become unresponsive, whether they are breathing or not breathing and if they are baby, child or adult.

This leaflet is designed to give a summary of general advice. This advice is no substitute for first aid training (see 'Further Reading' below to find out more about St John Ambulance and British Red Cross training courses).

If someone is unresponsive and breathing

Ce qu'il faut rechercher

If someone is not responding to you and you think they are unresponsive, ask loudly: 'Are you alright?' or 'Open your eyes'. If they don't respond, pinch their earlobe or gently shake their shoulders. If they still don't respond, then you can presume they're unresponsive.

Ce qu'il faut faire

Step 1 of 5: Open the airway

  • Place one hand on the person's forehead and gently tilt their head back. As you do this, the mouth will fall open slightly.

  • Place the fingertips of your other hand on the point of the person's chin and lift the chin.

Step 2 of 5: Check breathing

  • Regardez, écoutez et sentez une respiration normale - mouvement de la poitrine, sons et respirations sur votre joue. Faites cela pendant dix secondes au maximum.

Step 3 of 5: Put them in the recovery position

  • This will keep their airway open.

  • Kneel down next to them on the floor.

  • The next three steps are for if you find the person lying on their back. If you find them lying on their side or their front you may not need all three.

  1. Place their arm nearest you at a right angle to their body, with their palm facing upwards.

  2. Prenez son autre bras et placez-le sur sa poitrine de façon à ce que le dos de sa main soit contre la joue la plus proche de vous, et maintenez-le ainsi. De l'autre main, soulevez son genou arrière et tirez-le vers le haut jusqu'à ce que son pied soit à plat sur le sol.

  3. Now you're ready to roll them on to their side. Carefully pull on their bent knee and roll them towards you. Once you've done this, the top arm should be supporting the head and the bent leg should be on the floor to stop them from rolling over too far.

Step 4 of 5: If you suspect spinal injury

  • If you think the person could have a spinal injury, you must keep their neck as still as possible. Instead of tilting their neck, use the jaw thrust technique: place your hands on either side of their face and with your fingertips gently lift the jaw to open the airway, avoiding any movement of their neck.

Step 5 of 5: Call for help

  • Once you've put them safely into the recovery position, call 999 or 112 for medical help.

  • Until help arrives, keep checking the person's breathing.

  • If they stop breathing at any point, call 999 or 112 straightaway and get ready to give them CPR (cardiopulmonary resuscitation - a combination of chest pressure and rescue breaths).

If someone is unresponsive and not breathing

If an adult is unresponsive and not breathing, you'll need to do cardiopulmonary resuscitation (CPR).

CPR involves giving someone a combination of chest compressions and rescue breaths to keep their heart and circulation going to try to save their life. If they start breathing normally again, stop CPR and put them in the recovery position.

Ce qu'il faut faire

If someone is with you, get them to call 999 or 112 for emergency help and ask them to get an automated external defibrillator (AED) if one is available.

How to perform CPR on an adult

Step 1: Giving chest compressions

  • Kneel down beside the person on the floor, level with their chest.

  • Place the heel of one hand towards the end of their breastbone, in the centre of their chest.

  • Place the heel of your other hand on top of the first hand and interlock your fingers, making sure you keep the fingers off the ribs.

  • Lean over the person, with your arms straight, pressing down vertically on the breastbone, and press the chest down by 5-6 cm (2-2½ in).

  • Release the pressure without removing your hands from their chest. Allow the chest to come back up fully - this is one compression.

  • Repeat 30 times, at a rate of about twice a second or the speed of the song 'Staying Alive'.

  • Give two rescue breaths.

Step 2: Giving rescue breaths

  • Ensure the person's airway is open.

If the person starts breathing normally again, stop CPR and put them in the recovery position.
