CPR stands for cardiopulmonary resuscitation. It’s a life saving medical procedure which is given to someone who is in cardiac arrest. It helps to pump blood around the person's body when their heart can’t.

To carry out CPR a person presses firmly up and down on the casualty’s chest (chest compressions) and gives them a series of rescue breaths to help save their life when they are in cardiac arrest.

To maximise the chance of survival for a cardiac arrest victim, timely intervention is crucial.

For every minute that passes without treatment, the survival rate decreases by 10% so the quicker you can react and commence CPR and Defibrillation, the better.

Below is a short guide of what to do in a medical emergency when someone suffers a cardiac arrest and requires CPR and Defibrillation. Remember, every second counts so the quicker you can react, the greater chances of survival for the patient.
