Restart a heart day banner. October 16th. #9for9 #RestartAHeart #CallPushShock

If you know how to restart a heart, you can help save a life.

  • Only one in 10 people survive cardiac arrest.

  • Cardiac arrest can affect people of every age.

  • 8 in 10 out-of-hospital cardiac arrests happen in our homes.

What is cardiac arrest?

If you are in cardiac arrest, you will:

  • collapse
  • stop breathing normally
  • your will heart stop
  • your blood stops flowing
  • your brain stops receiving oxygen.

How to restart a heart

You can easily restart a heart by following 3 simple steps: CALL PUSH SHOCK

CALL: Triple Zero

Ask for an ambulance. The operator will talk you through what to do

PUSH: start Cardiopulmonary Resuscitation (CPR)

Push hard and fast on the centre of the chest to the rhythm of ‘stayin’ alive’.

Don’t worry – you can’t do any harm.

SHOCK: using An automatic external defibrillator (AED)

This is a portable machine that shocks the heart back to a rhythm.

Find out how to locate your nearest AED and how to register an AED.

What to do if you see someone in cardiac arrest

If you see someone in cardiac arrest, it is important to follow the DRSABCD steps outlined below.


Ensure the area is safe for yourself, others and the patient.

Check for a response by asking for a name and squeezing shoulders. 

Call triple zero (000) for an ambulance. They will stay on the line and talk you through what to do.

Open mouth and if foreign material is present, place in recovery position and clear airway with fingers.

Check for breathing. Look, listen and feel for breath.


Start CPR 

  1. Place both hands in the centre of the chest.
  2. Compress the chest – push down hard, don’t be scared. 
    • You should give approximately 100-120 compressions per minute (almost 2 compressions per second).
    • Compress to about 1/3 the depth of the chest – this equates to more than 5 cm depth in adults, 5 cm in children, and 4 cm in infants.
  3. Perform chest compressions continuously. 

Remember – don’t be scared – it's better to have a go – you may just save their life.

If there is someone else present, ask them to locate an Automatic External Defibrillator (AED). Do not leave the casualty to look for an AED if you are alone – continue with CPR.

An AED is a lifesaving device that can give your heart an electric shock when it has stopped. An AED will guide you through the defibrillation process and audibly take you through each step. Don’t worry, the AED will not deliver a shock unless it detects a shockable rhythm (for example, the heart is not beating properly).

Remember to download the AED Tasmania App to your phone and locate your nearest AED now.

What is Restart a Heart Day?
