How Many AEDs Does Your Facility Need?
Installing an Automated External Defibrillator (AED) is an important step toward improving emergency preparedness, but many organizations are unsure how many devices they actually need.
Proper AED placement and coverage can significantly impact survival rates during sudden cardiac arrest events.
Why AED Placement Matters
In a cardiac emergency, every minute without defibrillation reduces survival chances.
AEDs must be:
Easily accessible
Clearly visible
Available within a 1–3 minute response time
If an AED cannot be reached quickly, its effectiveness is reduced.
General AED Placement Guidelines
While every facility is different, a common guideline is:
One AED per building or floor, depending on size
Additional units for high-traffic or large facilities
Coverage within a 1–3 minute walking distance
Large facilities may require multiple devices for full coverage.
Factors That Determine AED Quantity
Organizations should consider:
Building size and layout
Number of occupants or visitors
Accessibility of different areas
Risk level of activities performed onsite
Proximity to emergency services
High-traffic or high-risk environments often require additional AED coverage.
Common Placement Mistakes
Many organizations unintentionally reduce AED effectiveness by:
Storing AEDs in locked rooms
Placing devices in low-visibility areas
Failing to mark AED locations clearly
Not training staff on device locations
Accessibility is just as important as availability.
Training and Awareness Are Essential
Even the best AED placement plan fails if people don’t know where devices are located.
Organizations should ensure:
Staff are trained annually
AED locations are clearly mapped
Emergency response plans include AED use
Determining how many AEDs are needed is not just a compliance question, it is a life-safety decision.
RYNO Public Safety Solutions helps organizations assess facility layouts and design AED placement plans that maximize response time and effectiveness.
