What Are AED Consumables and Why Do They Matter?

Defibrillator consumables are components of an Automated External Defibrillator (AED) that have limited lifespans and must be replaced periodically to ensure the device is functional when needed. These include:

• AED batteries
• Adult and child electrode pads
• Pad-pak battery and pad combination units
• Connectivity modules and sensors

According to the Australian Resuscitation Council, public access defibrillators must be properly maintained and checked regularly¹. Replacing consumables before expiry is crucial because:

• Expired pads may not conduct electricity effectively.
• Old batteries can cause the AED to malfunction or fail to power up.
• Non-compliant consumables can void device warranties or violate safety protocols.

Sudden cardiac arrest affects more than 25,000 Australians annually². Ensuring your AED has fresh batteries and pads could save a life.

Electrode Pads for Adults and Children

AED pads, or electrodes, are adhesive patches that deliver the shock from the defibrillator to the patient’s chest. These pads must be replaced after every use or once they expire — typically every 2–4 years depending on the model.

Types of AED pads available:

• HeartStart HS1 Adult Pads – For use with Philips defibrillators.
• HeartStart HS1 Child Smart Pads – Designed for patients under 8 years or 25kg.
• Cardiac Science Powerheart G5 Pads – Durable and pre-connected for rapid use.
• HeartSine Pink Pad-Pak (Paediatric) – Combines pads and battery for child-specific AED use.

Using paediatric pads is critical when treating children, as they deliver a lower shock level appropriate for smaller bodies. Make sure to have both adult and child pads on hand if your AED supports paediatric defibrillation.

Replacement tips:

• Store pads in their sealed pouch until use.
• Check the packaging regularly for damage or expiry.
• Avoid exposure to extreme heat or moisture, especially in outdoor cabinets.

How to Choose the Right Defibrillator Consumables

Selecting AED consumables can be confusing due to brand-specific requirements. Here’s a guide to simplify your choice.

Match your consumables with:

1. AED Brand & Model – Philips, HeartSine, Cardiac Science, etc.
2. Use Case – Paediatric vs. adult use
3. Storage Environment – Indoor or outdoor conditions
4. Expiry Dates – Choose items with long shelf life if usage is infrequent

Tips:

• Use your AED’s instruction manual to identify compatible part numbers.
• Buy in bulk to reduce replacement cost per unit.
• Set up calendar reminders for routine inspections and replacements.

Many suppliers offer AED consumable bundles, which include:

• 1 adult pad set
• 1 child pad set
• 1 backup battery
• 1 signage kit or inspection checklist

AED Batteries: Powering Your Life-Saving Device

AED batteries are one of the most critical consumables. These high-capacity lithium batteries typically last between 2–5 years, depending on the model and usage.

Types of AED batteries we offer:

• HeartStart M5070A Battery – Suited for Philips HS1 and FRx defibrillators.
• Cardiac Science Powerheart G3 & G5 Batteries – Colour-coded and model-specific.
• HeartSine Pad-Pak Systems – Combine battery and electrodes in a single unit.
• CARDIACT Miniature Module with IoT Sensor – Monitors AED status remotely.

Each AED model requires a specific battery type, so compatibility is key. For example, using a G5 battery in a G3 unit can damage the device or result in failure during use.

When to replace:

• Check the expiry date on the battery label.
• Replace immediately after the AED is used.
• Schedule proactive replacement every 4 years or as advised by the manufacturer.

Combination Packs & Smart Consumables

Some AED brands simplify maintenance with combination consumables like Pad-Paks, which include both the battery and electrode pads in a single cartridge. These are especially common in HeartSine models.

Featured products:

• HeartSine Paediatric Pink Pad-Pak – Simplifies replacement for schools or sports clubs.
• HeartSine Adult Pad-Pak – For general workplace or community use.
• CARDIACT IoT Sensor Module – Provides remote status updates via smart monitoring.

Combination consumables are particularly useful for:

• Organisations with multiple AEDs in the field
• First responders requiring fast replacement
• Remote or low-maintenance environments

Smart consumables like the CARDIACT module enhance compliance by notifying staff when the AED requires attention, such as pad expiry or low battery.
