What To Do In Case Of Cardiac Arrest?

The victim is not breathing…What are you doing ?

If the victim is unconscious and not breathing normally, chest compressions and rescue breaths should be given.


  1. Check that the victim is not reacting and is not breathing normally (see section on unconsciousness)
  2. Ask someone to call emergency services and immediately bring an automated external defibrillator (if available). Do all of this yourself if you are alone.
  3. Start by performing 30 chest compressions.
  4. Then practice 2 breaths.
  5. Alternate 30 chest compressions and 2 breaths.
  6. Continue resuscitation until emergency help arrives and continues resuscitation, or the victim resumes normal breathing.

  • Place the victim on a hard surface, usually on the ground.
  • Kneel next to the victim
  • Place the heel of one of your hands in the middle of his chest
  • Place the heel of the other hand on your first hand.
  • Unite your two hands. Do not press on the ribs or the lower part of the sternum.



  • Position yourself so that your shoulders are directly above the victim’s chest. Arms outstretched, vertically compress the sternum by pushing it down 5 to 6 cm.
  • After each pressure, allow the victim’s chest to return to its original position to allow blood to return to the heart. Hold your hands on the sternum.




  • The duration of the compression should be equal to that of the release of chest pressure.
  • Perform 30 chest compressions at a rate of 100 per minute, or approximately 2 compressions per second.
  • Then perform 2 breaths using the mouth-to-mouth technique.






  • Tilt the victim’s head back again and lift their chin3
  • Place one hand on his forehead and pinch his nostrils between your thumb and forefinger.
  • With the other hand, hold his chin to open his mouth
  • Inhale normally, lean towards the victim and completely cover their mouth with yours





  • Slowly and steadily blow air into the victim’s mouth while checking that their chest rises. Each breath lasts approximately 1 second.
  • While keeping the victim’s head tilted back and their chin up, straighten up slightly to check that their chest is lowering on the exhale.
  • Inhale normally again and practice a second breath.
  • Properly reposition your hands and perform 30 more chest compressions.
