The Right Defibrillator Pads for Different Ages
Defibrillator pads are a core part of any automated external defibrillator (AED) setup. They’re the sticky pads that go directly on the chest during an emergency, helping the AED deliver a lifesaving shock. But not all pads are the same. The type you need changes depending on the size and age of the person they might be used on.
Different ages mean different body sizes, heart rhythms, and shock levels. What works safely for an adult can be too much for a child. That's why knowing which defibrillator pads to keep on hand matters for homes, schools, workplaces, and anywhere kids and adults might need care.
If you're stocking or checking your AED, it's not just about having pads. It's about having the right ones. When seconds count, the last thing you want is to pause and question whether what you've got will work.
Adult vs. Child Pads: What’s the Difference
The biggest difference between adult and child pads is the amount of energy the AED is set to deliver once they’re connected. Adult pads tell the AED to use a full-strength shock. That’s enough to help restart a grown-up’s heart, but far too much for a child.
Child-specific pads lower the energy dose to something that’s safer for younger bodies. Children’s hearts are still growing, and their chests are smaller, which means any shock needs to be carefully adjusted. Using adult pads on a child can cause more harm than good.
There’s also a difference in where the pads go. With adults, you typically place one pad on the upper chest and the other on the lower side. With children, placement is usually front and back. Child pads usually include diagrams to show this clearly.
Most modern AEDs are smart enough to detect which pads are plugged in. If they sense child pads, they switch to paediatric mode automatically, adjusting the prompts and energy. That automatic shift can help someone acting under stress feel more confident in the moment.
Restart the Heart stocks defibrillator pads designed for both adults and children, and you’ll find compatible options for major AED brands like Lifepak, HeartSine, Philips, Zoll, and Defibtech.
When to Use Child Pads
Children under eight years old or weighing less than around 25 kilograms should always be given a lower-energy shock, which is what child pads are for. It’s not about age alone, but also body weight and size. If there’s any doubt, it’s safer to go with the pads made for smaller bodies.
There are lots of public and private places where child pads are needed:
• Schools, childcare centres, and kindergartens
• Holiday parks, campsites, and playgrounds
• Homes where children live or visit often
And it goes beyond just having them. Pads should be stored in a spot that’s fast to grab. A labelled shelf, zipped into an AED case, or kept in a marked cupboard works well. The key is avoiding the last-minute scramble to figure out which pair is for adults and which is for kids.
How Universal Some Pads Really Are
Not all defibrillator pads work with every brand or model of AED. Shape, plug style, and software might change even between models from the same company. That’s why it’s so important not to assume that one pack fits all.
There are some AEDs that come with a single set of pads and use a “paediatric key” instead. That key tells the AED to switch into kid mode when used, so new hardware isn’t needed. But that’s only true for certain types of defibs, and many still need separate pad sets.
Before buying new pads or stocking a public access AED, it's a good idea to check the sticker on the device or its instruction booklet. Matching the wrong pair could mean they don’t stick right or don’t plug in, which could waste time during an emergency.
Restart the Heart provides clear details about which pad sets suit each model, so you can check compatibility directly on our product listings.
Seasonal Checks for Public and Travel AEDs
By mid to late February, much of Australia is still dealing with the last stretch of summer heat. That heat can play tricks on medical gear and storage spaces if no one’s keeping watch. AED pads, in particular, use adhesive that can dry out fast in hot, closed-up boxes. Batteries can lose charge faster as well.
If you’ve taken your AED out to events, travel, or worksites, it’s a good time for a quick look-over:
• Check the expiry date on the pad packaging
• Make sure adhesive strips are still intact and stored flat
• Keep spare pads in air-conditioned spots or indoor storage if possible
This applies to workplaces, public parks, construction sites, and even utes with mobile defib kits. A once-a-month check doesn’t take long but can save time when it counts most.
Ready for All Ages in One Place
The best way to avoid second-guessing during an emergency is to have pads for both adults and children handy. That might mean mounting a second packet in the wall box, slipping a labelled set into a storage drawer, or making sure your grab bag is fully kitted out.
When things go wrong, what people look for most is clarity. Having everything in one place, clearly marked and already fitted to your model, makes that action faster.
• Check your current AED setup today
• Open the storage pouch or wall unit and see if both pad types are packed
• If you run a venue, update your staff or family on where each kind is kept
When you already know what’s inside the kit, and for who, it clears the path in your mind before you even start. That built-in confidence can go a long way when there’s panic in the room.
Confidence Comes from Knowing Your Gear
Keeping the right defibrillator pads on hand isn’t about ticking a box. It’s about being ready to act for anyone, no matter their size. That readiness doesn’t come from hope alone, it comes from preparation, practice, and knowing exactly what you’ve got in front of you.
These aren’t details to leave to chance. Whether someone is checking an AED at home, in a caravan, or at a sports club, being sure about which pads are packed and where they are makes a difference.
With the right match and good storage habits, you give yourself more time to act. And in a real emergency, every second matters.
