Carefully open the airway. This can be done by carefully placing your hand on the forehead and two fingers at the chin and gently tilting the head to the back. This will help to maintain an open airway.
Check for normal breathing. This means checking to find out if the casualty is breathing normally this should not take more than 10 seconds so that the vital organs do not lack oxygen. Look at the chest and abdominal movements, if no movements, then the casualty is not breathing. You can also listen to the sounds of breathing, and feel for the warmth of the breath
If the casualty is not breathing normally, send someone to call an ambulance, and start chest compressions. Do 30 chest compressions at the rate of 100-120 per minute.
Now combine chest compressions with rescue breaths.
Then return your hand back to the right position for chest compression and give 30 chest compressions use the heel of both hands when performing chest compressions and 2 rescue breaths. If the paramedics have not arrived yet continue with this pattern of 30 chest compressions and 2 rescue breaths.
Points to note.
This is the Basic First Aid Training procedure for Cardiopulmonary resuscitation (CPR).
