How to Use an AED Safely: CPR, AED Limitations & Maintenance Guide (Canada)

Understanding AED Use in Cardiac Emergencies

An Automated External Defibrillator (AED) is a life-saving device used when someone is unresponsive and not breathing normally. Knowing what to do if someone collapses at work or how to respond using CPR and an AED can significantly improve survival.

AEDs are designed to be simple to use, but understanding their limitations and proper maintenance is just as important as knowing how to operate them.

Scenario: Team Saves Colleague at Worksite

At the Hebron Gravity Base Structure site, a worker from Clarenville was saved thanks to the quick actions of a trained emergency response team.

Adrian Tarrant, along with Jamie Budden and Ashley Perham, responded to a call over the radio reporting an unconscious colleague.

When Tarrant and Perham arrived, Budden had already begun CPR. The team worked together seamlessly:

• CPR was continued without interruption
• An AED was applied and used
• Roles were shared to maintain consistent care

After delivering a second shock with the AED, the team was able to restore a pulse. The worker was then transported to a healthcare facility.

Their coordinated response and training were credited with saving the man’s life—highlighting the importance of teamwork and preparedness in Canadian workplaces, including those in Manitoba.

AED Limitations: When and Where to Use Caution

AEDs are highly effective, but certain conditions require awareness:

Water and Wet Environments

• AEDs should not be used in standing water
• Move the person to a dry area if possible
• Dry the chest quickly before applying pads

Metal Surfaces

• AEDs can be used on metal (e.g., construction sites), but:
  • Ensure no one is touching the person during shock
  • Avoid contact with conductive surfaces during use

Explosive or Flammable Environments

• Avoid using an AED near flammable gases or vapours
• Sparks from the device could pose a risk in rare cases

Movement or Vibration

• Excessive movement (e.g., in vehicles) can interfere with analysis
• Keep the person as still as possible during AED use

These considerations are commonly discussed in AED training courses across Canada.

Importance of AED Maintenance

An AED is only effective if it is ready to use.

Key Maintenance Checks

• Battery status: Ensure it is charged and within expiry
• Electrode pads: Check expiration dates and packaging integrity
• Self-test indicators: Many AEDs run automatic checks—monitor status lights or alerts
• Accessibility: Ensure the AED is easy to locate and not obstructed

Workplaces in Winnipeg and across Manitoba often assign responsibility for regular AED checks as part of safety programs.
