The following steps are designed to assist in the implementation of an AED program and help preserve the principle of continuity of emergency patient care. Once 911 is called every person treated with an AED at a public site will become the responsibility of EMS personnel, the EMS system, and the system’s medical directors and subsequent care providers.
  1. AED in action

    Acquire an AED. AEDs can be purchased by the general public through medical supply companies or online vendors. They are manufactured and sold under guidelines approved by the Food and Drug Administration (FDA) and may require a physician's prescription for the device. Get a prescription from a physician or osteopath of your choice, or request a prescription free of charge from King County Emergency Medical Services.

  2. Acquire Medical Direction. Acquire guidance on how to use your AED by getting Medical Direction from a physician of your choice, or requesting Medical Direction free of charge from the Seattle or King County EMS Medical Director.

  3. Register your AED(s) so 911 dispatchers can quickly direct a caller to the location of the nearest AED.  Please report any changes to your AED registration information (device, location, site coordinator information, etc.).

  4. Training. Provide training to a reasonable number employees, staff, or family members on CPR/AED use, consistent with national standards for CPR and AED use.

  5. Select a site coordinator to oversee your AED program.

  6. Maintenance Plan. Develop a plan for regular checks and maintenance of your device consistent with the manufacturer’s guidelines, including routine check of battery operation and replacement of expired chest pads.

  7. After AED Use- Contact King County Emergency Medical Services (EMS), as soon as possible after an AED use, even if no shock was delivered (required in King County, per RCW 70.54.310).  Contact or (206) 296-4693.  If you use an AED management company, please contact EMS first.

  8. Site visits can be provided by local fire departments or King County EMS if you need help with deciding:
    • How many AEDs you need for your building
    • Where AEDs should be placed in your building
    • What level of accessibility the AED should have
    • How to keep the AED secure

    To arrange a site visit, contact Laura Miccile, CPR/PAD Program Manager, at 206-477-8664 or at
