Using AED with CPR creates the most effective response to cardiac arrest, combining chest compressions that maintain blood flow with electrical shocks that can restore normal heart rhythm. When someone collapses from sudden cardiac arrest, every second counts. The difference between life and death often comes down to how quickly bystanders can start CPR and apply an Automated External Defibrillator (AED).
Picture this: You’re at your local shopping centre when someone suddenly collapses nearby. Your heart races as you recognise the signs of cardiac arrest. You know CPR, but there’s an AED on the wall. Which do you use first? Do you stop CPR to get the AED? What if you’ve never used one before?
These questions paralyse people in the crucial first minutes when action matters most. This guide will walk you through the complete integration protocol for using AEDs with CPR in Australia, giving you the confidence to respond effectively in a cardiac emergency.

Key Takeaways
- Using AED with CPR works together to maximise cardiac arrest survival rates—one maintains blood flow while the other corrects heart rhythm
- Early CPR before defibrillation maintains blood flow to vital organs and improves AED effectiveness
- Under WHS laws, workplaces must assess risks and provide appropriate first aid resources; guidance recommends AEDs in higher‑risk or larger workplaces where cardiac arrest risk or ambulance delay is significant.
- Public access defibrillation programs are expanding across Australia, with AEDs in shopping centres, airports, and community facilities
- Proper training ensures confident, effective emergency response
- Paediatric AED use differs from adults: for children 1–8 years, paediatric pads and reduced energy are preferred, though adult pads may be used if paediatric options are unavailable; children over 8 years generally use standard adult settings
Understanding Using AED With CPR: Why Both Matter
The survival rate for out-of-hospital cardiac arrest in Australia is only about 10%. However, In some cases where CPR and an AED are used within the first 3–5 minutes, survival can rise to around 60–70%. These aren’t just statistics—they represent thousands of Australian lives that could be saved each year.
How CPR Before Defibrillation Saves Lives
When the heart stops beating effectively, the brain begins to die within 4-6 minutes due to lack of oxygen. CPR doesn’t restart the heart, but it manually pumps blood through the body, delivering oxygen to the brain and vital organs. High‑quality chest compressions can provide a fraction of normal blood flow—enough in many cases to help protect the brain and keep the heart more responsive to defibrillation
The Australian Resuscitation Council’s chain of survival highlights this clearly: early recognition and call for help, early CPR, early defibrillation, and early advanced care. CPR comes before defibrillation—not instead of it—so that when a shock is delivered, the patient has the best possible chance of survival.
When to Use AED vs CPR: The Decision Framework
You don’t choose between CPR and an AED—you use both, in the right sequence. Start CPR immediately if someone is unresponsive and not breathing normally. Don’t delay CPR while someone fetches the AED. Start compressions straight away, and continue until the AED arrives.
The AED is applied as soon as it becomes available, without stopping CPR for more than 10 seconds. You don’t stop CPR and switch to the AED—you integrate the AED into your CPR routine. The device will tell you when to pause for rhythm analysis and when to resume compressions.
Table 1: CPR and AED Decision Matrix
Situation | Action | Reasoning |
Person collapses, not breathing | Start CPR immediately | Brain damage begins within 4-6 minutes |
Performing CPR alone | Continue CPR, shout for help and AED | CPR maintains viability |
AED arrives during CPR | Pause briefly to attach, resume CPR | Minimise interruption to blood flow |
AED advises shock | Stand clear, deliver shock, resume CPR | Shock attempts to restore rhythm |
AED advises no shock | Continue CPR | Not all cardiac arrests are shockable |
AED Locations Australia: Finding Public Access Defibrillation
Mapping Public Access Defibrillation Points
Several resources help Australians locate nearby AEDs, including Register My AED, the GoodSAM app, and state-based emergency services apps like Emergency+. When you call Triple Zero (000), the operator can direct you to the nearest registered AED.
Common AED locations include shopping centres, airports, sports facilities, schools, government buildings, large office complexes, hotels, and community centres. The challenge? Many AEDs remain unregistered. If your workplace or community organisation has an AED, registering it with national databases could save a life.
Workplace AED Requirements Across Australian States
Work Health and Safety (WHS) legislation doesn’t mandate AEDs for all Australian workplaces, but it does require employers to provide appropriate first aid equipment based on risk assessment. High-risk workplaces where AEDs are strongly recommended include fitness centres, mining and construction sites, electrical utilities, aged care facilities, and remote worksites where ambulance response exceeds 10 minutes.
Table 2: Workplace AED Assessment Criteria
Factor | Low Risk | High Risk |
Number of employees | <25 | >100 |
Age demographics | Mostly under 40 | Significant over-50 population |
Physical demands | Sedentary | High physical exertion |
Ambulance response time | <5 minutes | >10 minutes |
AED Recommendation | Consider | Strongly recommended |
AED Usage Guidelines Australia: Step-by-Step Integration Protocol
Step 1: Scene Safety and Emergency Call
- Check scene safety, then check the person for responsiveness
- Shout for help, ask someone to call Triple Zero (000)
- Ask someone specific to locate and bring an AED
Step 2: Start CPR Immediately
- Place heel of hand in centre of chest, other hand on top
- Compress hard and fast: at least 5cm deep, 100–120 compressions per minute
- Provide 30 compressions followed by 2 rescue breaths
Step 3: Apply the AED When Available
- Turn on the AED and follow voice instructions
- Expose and dry the chest
- Attach pads to bare chest as shown on diagram
- Ensure pads make full contact with skin
Step 4: Follow AED Prompts
- "Analysing rhythm" → Stop CPR, stand clear
- "Shock advised" → Ensure everyone is clear, press shock button
- "Shock delivered" → Immediately resume CPR
Step 5: Continue the Cycle
- Resume CPR for about 2 minutes
- The AED will prompt for another rhythm analysis
- Repeat until paramedics arrive or person breathes normally
AED with Paediatric Victims: Special Considerations
For children (1-8 years), use paediatric pads if available. If paediatric pads aren’t available, use adult pads.
For infants (<1 year): Paediatric pads/AED preferred; if only adult available, use it – typically anterior-posterior placement to avoid overlap —some shock is better than no shock.
Key differences for children include using one or two hands for compressions depending on size, compressing about one-third the depth of the chest, and for infants, using two fingers for compressions at 4cm depth.
Using AED With CPR Training Courses: Building Confidence and Competence
What Quality Training Programmes Cover
Nationally recognised courses include practical skills development with high-quality chest compression technique on manikins, rescue breath delivery, AED pad application, and scenario-based learning that simulates real emergencies. Assessment includes both practical demonstration and knowledge components to ensure competency.

Finding Accredited Training in Australia
Look for courses delivered by Registered Training Organisations (RTOs) that provide nationally recognised qualifications:
- HLTAID009 Provide cardiopulmonary resuscitation (2-3 hours, annual renewal recommended)
- HLTAID011 Provide First Aid (6-8 hours, valid 3 years with annual CPR update)
- HLTAID012 Provide First Aid in an education and care setting (designed for childcare workers and teachers)
The Australian Resuscitation Council recommends CPR skills be refreshed annually, as technique quality deteriorates over time.
Common Mistakes and How to Avoid Them
Integration Errors That Delay Treatment
Common mistakes include:
- Delaying early CPR while searching for an AED (always start early CPR early / immediately)
- Stopping CPR for too long during AED application (minimise hands-off time to less than 10 seconds)
- Incorrect pad placement (ensure pads are on bare, dry skin and don’t overlap)
- Not resuming CPR immediately after shock delivery
- Removing AED pads when the person recovers (leave them attached)
Overcoming Hesitation in Real Emergencies
Australian law protects people who provide emergency assistance in good faith. The Civil Liability Act in each state provides immunity from liability when you act in good faith without expectation of payment. Modern AEDs are remarkably safe—they analyse heart rhythm and will only advise a shock if needed. Without intervention, cardiac arrest is fatal. Using AED with CPR, helps make survival possible.

Using AED with CPR in Australia: Be Ready to Act When Every Second Counts
Using AED with CPR isn’t about choosing one technique over the other—it’s about understanding how these complementary interventions work together. CPR maintains blood flow to vital organs while the AED corrects abnormal heart rhythms. Together, they give cardiac arrest victims the best chance of survival.
The protocols are straightforward: start CPR immediately, integrate the AED when it arrives, follow the device’s prompts, and minimise interruptions to chest compressions. Australia’s expanding public access defibrillation program means AEDs are increasingly available, but technology alone doesn’t save lives—people do.

Frequently Asked Questions
Can I use an AED without formal CPR training?
Yes. AEDs are designed for use by untrained bystanders with clear voice instructions and visual prompts. However, formal training significantly increases confidence and the likelihood that you’ll act in an emergency, which is why many Australians choose to complete nationally recognised training.
How long should I perform CPR before using an AED?
Are AEDs mandatory in Australian workplaces?
AEDs aren’t universally mandatory, but WHS legislation requires employers to provide appropriate first aid equipment based on risk assessment. High-risk workplaces—including gyms, remote sites, and large facilities—should have AEDs as part of their first aid equipment.
What's the difference between adult and paediatric AED pads?
Paediatric pads deliver reduced electrical charge (50-75 joules vs 150-200 joules) appropriate for children’s smaller bodies. Use paediatric pads for children 1-8 years old, but if only adult pads are available, use them—some shock is better than no shock.
Will an AED shock someone who doesn't need it?
No. Modern AEDs analyse the heart’s electrical rhythm before advising a shock. They only recommend a shock when detecting specific abnormal rhythms that defibrillation can correct. If the heart is beating normally, the AED will advise “no shock needed.”
