So you've decided you want a defibrillator. Great. That's genuinely one of the better decisions you can make for your workplace, your club, or your community space.
If you've started looking at options you might find yourself a little confused by all the different brands, models and features. What do they all mean? Semi-automatic. Fully automatic. IP55. Biphasic. QShock. CPR Advisor. It reads like a spec sheet for a piece of mining equipment, not something you're buying to potentially save an employee's life.
Here's the thing: most of those terms aren't that complicated once someone explains them plainly. That's what this article is for. By the end of it, you'll know exactly what matters, what doesn't, and which of our five models is the right one for your organisation and the people likely to be using it.
What does a defibrillator actually do?
When someone goes into sudden cardiac arrest, their heart isn't just stopping - it's firing in a chaotic, disorganised way that means it can't pump blood properly. A defibrillator delivers a controlled electrical shock to interrupt that chaos and give the heart a chance to reset itself back into a normal rhythm.
CPR - chest compressions - are different to what a 'defib' does. CPR keeps blood moving to the brain and organs so they keep getting oxygen. But CPR alone doesn't fix the underlying electrical problem which caused the cardiac arrest. That's the defib's job. Together, they're the most effective response to cardiac arrest you can have outside a hospital.
Here's the most telling fact you will ever read about cardiac arrest. The survival rate of the victim drops by roughly 10% for every minute that passes without them receiving defibrillation. After ten minutes, the odds get very, very poor. You can essentially say goodbye. But get a defib on someone within three to five minutes alongside CPR, and survival rates can reach up to 70–85%.
That's not a small thing. That's the difference between someone going home and someone not going home.
"But I don't know how to use one."
This is the bit that tends to puts people off using a defibrillator, but it really shouldn't.
Because modern defibrillators are designed specifically for bystanders to use - not paramedics. The machine itself, actually talks you through every single step. They analyse the heart rhythm themselves. They tell you exactly when a shock is needed. Some models even deliver it automatically without you having to do anything beyond sticking the pads on.
And here's something a lot of people don't know: you cannot accidentally shock someone whose heart doesn't need it. The device won't allow it. It will only ever advise or deliver a shock when it detects a shockable rhythm. There is basically no version of events where grabbing a defib and using it can make things worse.
So if you've been putting off buying one because you're worried your staff won't be able to use it - that's not a reason to wait. It's actually a reason to get the right model, which leads us to the one decision that matters most.
The main choice to decide on a defib: semi-automatic or fully automatic?
Every defibrillator in our Results First Aid range analyses the heart rhythm on its own. The difference is in what happens next.
A semi-automatic AED charges up, detects a shockable rhythm, and then prompts the user to press the shock button. That's the moment where someone has to make that call and push the button.
A fully automatic AED does exactly the same analysis - but it delivers the shock itself, exactly when it's needed. No buttons to push. No decision to make. It just acts.
Neither is more dangerous than the other. The AED will only shock when it needs to. The question is really about who is going to be using it under what circumstances.
If your workplace has trained first aid officers who do regular refresher training, a semi-automatic defib is completely fine. Those people are prepared, they know what's coming, and having that deliberate moment of action makes sense to them.
If however, it is likely that the defib in your organisation may be grabbed by someone who has never touched a defib before - a panicking office manager, a bystander at a community event, a tradie on a site who's just watched a colleague go down - a fully automatic model removes one more thing they have to think about when they can barely think straight. It removes hesitation in critical moments, when seconds count.
Honest advice: if you're not confident your team will maintain their training consistently - and most don't - go fully automatic. Drills are calm. Emergencies aren't. The fewer steps required at a critical time, the better.
The other defib features - what they mean and whether they matter
CPR coaching
All defibrillators give voice prompts during CPR. They'll tell you to start compressions, count out a rhythm, even tell you when to pause. That's all standard.
The HeartSine 500P goes further with something called a CPR Advisor. Using the same electrode pads already on the patient, it measures the actual force and rate of your compressions and coaches you based on what it detects: "Push harder." "Good compressions." "Push faster." It's not just a metronome - it tells you whether or not what you're actually doing is working.
For anyone who might be nervous, exhausted, or physically uncertain about whether they're doing enough, that feedback can make a huge difference.
The Mindray C2 models add a 7-inch colour screen with animated visual prompts running alongside the voice. For a trained responder trying to stay focussed during a longer resuscitation, having something to look at as well as listen to, can genuinely help.
The screen
The Mindray C1A models have no large display. But the C2 models have a 7-inch colour screen. Whether that matters depends entirely on your environment.
In a professional setting - large gym, a corporate office, a sporting facility with a proper first aid setup - the screen gives responders more to work with and keeps them oriented. In a community hall, small office, or suburban workplace, voice prompts alone do the job fine.
Don't pay for a screen you don't need one. But if your team would genuinely benefit from it, it's worth the step up.
Kids
All five models in our range can be used on children. The Mindray range has a built-in child mode - a simple switch on the device adjusts the energy level automatically for kids. No extra accessories are needed.
The HeartSine 500P requires a separate Paediatric Pad-Pak for children under 8 years or under 25kg. It's not expensive, but it's an extra thing to buy and keep track of. Of course if you're buying for a school, childcare centre, or any setting where kids are regularly present, this might be the best option for you.
IP rating
This rating tells you how well your the device handles water and dust. IP55 means it handles low-pressure water jets from any direction - which is good enough for most indoor and semi-sheltered environments. An IP56 rating, like the HeartSine 500P has, means it can handle more aggressive water exposure, making it the better choice for anything genuinely outdoors, near water, or on a dusty worksite.
For a standard office, the difference doesn't matter. For a construction company, a mine site, or a rural sports club, it can mean a lot.
Ongoing costs
Every AED needs its pads and battery replaced periodically, whether it's been used or not - they degrade over time just by sitting there.
The Mindray range has separate pads and batteries, each lasting 5 years from installation. The unit itself is covered by an 8-year warranty.
The HeartSine 500P uses a Pad-Pak - a single cartridge that combines the battery and electrode pads together, with one shared expiry date, that needs to be replaced every 4 years. So there is only one item to track, one item to replace. If your organisation manages multiple devices or has less formal maintenance schedules, that simplicity can be an important factor in your decision.

If you've read all of the above and you still can't decide, we've put together a short tool that asks you five questions about your environment and gives you a recommendation of which one is right for your needs, complete with the reasoning behind it. Takes about a minute to complete.
Our five models - the straight talk on each one
The most affordable option in our range, and for a lot of situations, it's the right one. Compact and straightforward, it comes with a wall cabinet included. Voice and visual prompts walk the user through every step. The shock button gives a trained responder a moment of deliberate action before delivery.
Mindray's ResQNavi technology is also a nice touch - if it detects that someone is taking longer than expected to attach the pads, it expands its guidance to match. Basically, it reads the situation and gives advice.
Inbuilt QShock technology ensures it delivers its first shock in under 8 seconds, which is faster than most AEDs on the market.
Good for: Small offices, retail environments, community centres, schools, any workplace with a reasonable number of staff who've done or are planning basic first aid training.
Skip it if: Your responders are more likely to be untrained bystanders - the fully automatic version is a better choice in these environments.
Essentially the same device as the semi-automatic model. Same build quality, same features, same warranty. The only difference is there's no shock button - the device will deliver a shock whenever it determines one is needed, without waiting for anyone to press anything.
For just $100 more than the semi-automatic model, it's worth a serious look if you have any uncertainty about the training levels of the people who are most likely to use it.
Good for: High-traffic public areas, hospitality venues, workplaces with rotating staff, any setting where a bystander rather than a trained first aider might be the first person on the scene.
Skip it if: Your first aid team is well-trained and regularly drilled - they don't need the fully automatic version and the semi-automatical model gives them more control.
The C2 model is another step up, as it includes a 7-inch colour screen showing animated CPR instructions alongside the voice prompts. It's a useful upgrade for environments where responders know what they're doing and want more information in front of them during a resuscitation.
The C2 models also support optional Wi-Fi and 4G connectivity through Mindray's AED-Alert system - so you can remotely monitor the device's status, get notified if something needs attention, and manage multiple units across a site. Useful if you've got a number of defibrillators and don't want to have to manually check them all.
The cabinet is included.
Good for: Gyms, sporting facilities, larger corporate offices, any workplace with a trained first aid team that would genuinely use what the screen offers.
Skip it if: Budget is a consideration and the screen isn't a priority. The C1A delivers the same core performance for $400 less.
Again this has everything the semi-automatic model has - colour screen, connectivity, cabinet - but with the shock always delivered automatically. It's the most capable Mindray in the range.
If you're buying for a large venue, an industrial site, or anywhere with high foot traffic and unpredictable responders, this is the one to consider. It does the most and asks the least of whoever picks it up.
Good for: Warehouses, transport hubs, large sporting venues, construction sites with a site office, healthcare-adjacent environments.
Skip it if: Your environment is small and your team is confident. You'd be spending on capability you're unlikely to need.
The HeartSine defibrillator is quite different from the Mindray range. It has no large screen and no automatic shock - but it has something none of the others do: proper real-time CPR feedback.
Using the electrode pads already attached to the patient, the CPR Advisor measures the actual force and rate of chest compressions and tells the responder whether they're effective. Not just "keep going" — but "push harder," "push faster," or "good compressions." It's the closest thing to having a paramedic next to you telling you how well your technique is working.
It's also the most portable device in the range - weighing just 1.1kg including the Pad-Pak. And it's the most weather-resistant- rated at IP56. Its 10-year warranty is two years longer than the Mindray range. And the Pad-Pak system (combining the battery and electrode pads in one cartridge, with a 4-year life, that can be replaced in 5 seconds) makes it the most maintenance-friendly setup we sell.
Good for: Outdoor environments, construction and mining sites, remote locations, sporting clubs, organisations that take CPR quality seriously, and anyone who needs a unit that can genuinely go anywhere.
Worth knowing: The wall cabinet is not included - add one if you need it. Paediatric Pad-Paks are sold separately for use on kids under 8 or 25kg.
Skip it if: You need a large screen or remote monitoring capability - the 500P doesn't have those.
