Defibrillator Failure Sparks Life-Saving Warning After Teen’s Close Call

A frightening incident involving a 13-year-old hockey player in Nova Scotia serves as a strong reminder that automated external defibrillators (AEDs) must not only be available—but properly maintained and ready to use.

According to an original report by CBC News, Kenzie Lahey’s near-death experience highlights how quickly a cardiac emergency can unfold and how critical CPR and AED response are in saving lives.

Defibrillator failure prompts teen’s warning

A Sudden Collapse on the Ice

While playing in a hockey tournament in Chester, Nova Scotia, Kenzie was struck in the chest by a puck and collapsed on the ice. Coaches initially believed he was having a seizure, but a paramedic in attendance quickly realized the situation was far more serious—Kenzie had no pulse and was not breathing.

“I really thought he was going to die,” said his mother, Tanya Lahey.

Paramedic Allan Keddy immediately began CPR as a doctor rushed over to assist. An AED was brought to the scene so responders could attempt to restart Kenzie’s heart.

When the AED Failed

Although the arena had a defibrillator, its battery was dead.

“If they’re not charged, they’re not going to work,” Lahey said. “You may as well not have them.”

CPR continued until paramedics arrived with a working AED. After one shock and several more chest compressions, Kenzie’s pulse returned. Against the odds, he survived.

Why AED Maintenance and Training Matter

This incident makes it clear that AEDs require regular inspection, battery checks, and accountability. In a cardiac emergency, even a short delay can be fatal.

Just as important is public training. Knowing how to perform CPR and confidently use an AED can mean the difference between life and death. That’s why enrolling in CPR and AED training courses—such as those offered by Winnipeg First Aid—is a practical step anyone can take to be prepared for emergencies in arenas, workplaces, and public spaces.

Learning Without Fear

Following the incident, the arena’s AED was serviced and its battery replaced. Additional defibrillators are also being distributed to public facilities across the province, along with training on how to use them.

Kenzie hopes others learn from his experience without becoming afraid.

“Don’t be afraid,” he said. “Just go out there and play.”

His mother now has one firm rule—Kenzie will only play hockey in arenas with working, Properly maintained defibrillators.

A Message for All Communities

This close call reinforces a simple but critical lesson: AEDs save lives only when they work, and people save lives when they’re trained. Regular maintenance, CPR education, and AED confidence go hand in hand.

Being prepared isn’t optional—because emergencies don’t wait.
