We often place our trust in technology—especially in those moments when every second counts.
But what if the very tool we rely on during an emergency turns out to be unreliable?
That unsettling concern is now affecting numerous Australians following a product recall.
What’s the problem?
According to the official recall notice, a circuit board component in some HeartSine samaritan public access defibrillators (PAD) may be faulty.
This defect can impair the device’s ability to function, potentially rendering it completely inoperable.
Even more concerning, the failure could occur at any stage—while the device is charging to deliver a shock, during the shock itself, or immediately after.
In other words, the defibrillator could fail right when it is needed most.
Thankfully, the issue was discovered during quality testing and not as a result of an actual emergency.
Nonetheless, the risk is significant enough that health authorities are not taking any chances.


Which devices are affected?
Not every HeartSine PAD model defibrillator is affected, but several models have units included in the recall.
The recall applies to a specific subset of the following models: 350P, 360P, 450P and 500P.
To determine if your device is included, check the serial number. Devices at risk begin with the numbers 21, 22, 23 or 24, followed by the letters B, D, E, G or H.
If you are unsure, it’s best to verify immediately. These devices are commonly found in community halls, gyms, workplaces and even private residences.
It is worth alerting neighbours, local groups and friends to check their units as well.
What should you do if you have an affected device?
If you discover that your defibrillator is part of the recall, do not panic—but act promptly.
Stryker, the manufacturer, has established a dedicated helpline and email address for affected customers.
You can contact them on 02 9170 9131 or email [email protected].
They will provide instructions on the next steps, including how to arrange for a replacement or repair.
Why does this matter?
Defibrillators play a critical role in Australia’s emergency medical response system.
In the event of sudden cardiac arrest, every moment matters. A working defibrillator can mean the difference between life and death.
That is why it is essential that every device within the community remains functional and ready to use.

This recall serves as a timely reminder for all of us to regularly inspect our emergency equipment.
Even if your device is not included in this particular recall, take the opportunity to check its battery, pads, and general condition.
You never know when you—or someone you care about—might depend on it.
A moment to reflect and act
This development raises an important question: how often do we truly inspect the tools meant to save lives?
Now might be the time to review what is on hand in our homes, clubs and local facilities.
We would like to hear from you. Have you ever encountered a situation where a defibrillator was needed? Is your device up to date? Has it been tested?
Your comments may help raise awareness and encourage others to take action.
