Can a Defibrillator Be Used on a Child? (What You Must Know Before Buying an AED)

Quick Answer

Yes, a defibrillator (AED) can be safely used on a child. However, the device must either have child-specific pads or a built-in child mode. Some AEDs require separate child pads, while others use universal pads suitable for both adults and children — which can be critical in an emergency.

Can You Use an AED on a Child?

Yes — AEDs are designed to be used on children as well as adults.

In Australia, AEDs are commonly used on:

• Children over 1 year old
• Teenagers and young adults
• Infants (in some cases, with appropriate settings or pads)

AEDs analyse the heart rhythm and only deliver a shock if needed, making them safe for use even by untrained people.

Why Child Compatibility Matters More Than Most People Realise

This is one of the most overlooked factors when buying a defibrillator.

There are three common types of AED setups:

1. AEDs That Require Separate Child Pads

• You must purchase paediatric pads separately
• Pads need to be swapped or selected during an emergency
• Often stored separately from the device

👉 Risk:
If child pads are not available or can’t be located quickly, treatment may be delayed.

2. AEDs With a Child Mode (Key or Button)

• Device switches between adult and child settings
• Still uses the same pads
• Requires user to activate the mode

👉 Risk:
In a high-stress situation, users may forget to switch modes.

3. AEDs With Universal Pads (Best Option for Most Buyers)

• Same pads used for both adults and children
• No switching required
• Simplest and fastest to use

👉 Why this matters:
In a real emergency, simplicity saves time — and time saves lives. See the table below:

What Happens If You Use Adult Pads on a Child?

AEDs are designed to be safe, but:

• Adult pads deliver a higher energy shock
• Child-specific pads or settings reduce the energy level
• Using the correct setup is recommended where available

👉 In an emergency, using an AED (even with adult pads) is better than doing nothing.

Where Child-Compatible AEDs Are Essential

If your AED could be used on a child, this is non-negotiable.

You MUST consider child compatibility if the AED is located in:

• Schools
• Childcare centres
• Sports clubs
• Gyms
• Public venues
• Medical centres
• Community facilities

👉 Many buyers overlook this — until it matters.

Best AED Option for Child Use

🟢 Smarty Saver AED Range (SM2 & SM4)

The Smarty Saver range is one of the most practical choices for environments where children may be present.

Why it’s ideal:

• Uses the same pads for adults and children
• No need to switch pads or modes
• Reduces hesitation in emergencies
• Lower ongoing cost (no need to buy separate paediatric pads)

👉 This makes it particularly suitable for:

• Schools
• Sports clubs
• Workplaces with public access

Real-World Risk: What Actually Happens in Emergencies

In theory:

• Users follow instructions perfectly
• Pads are available
• Settings are switched correctly

In reality:

• People panic
• Equipment is misplaced
• Instructions are missed

👉 This is why simpler AEDs are often safer in practice.

Cost Considerations for Child Pads

If your AED requires separate child pads:

• Additional cost: ~$100–$200
• Expiry: typically 2–5 years
• Must be replaced regularly

👉 Over time, this increases the total cost of ownership.

FAQs

Can a defibrillator be used on a child under 8?
Yes. Most AEDs include child settings or pads for children under 8 years or under 25kg.

Do all AEDs come with child pads?
No. Many require child pads to be purchased separately.

What is the safest AED for mixed environments (adults + children)?
AEDs with universal pads are generally the safest and simplest option.

Can you use an AED on a child without training?
Yes. AEDs provide step-by-step voice instructions.

Final Recommendation

If there is any chance your defibrillator may be used on a child:

👉 Choose an AED that:

• Supports child use
• Minimises steps in an emergency
• Reduces reliance on additional accessories

For most buyers, this means prioritising AEDs with universal pads.
