AUTOMATED EXTERNAL DEFIBRILLATOR (AED)

If you look around the public places you visit, you are likely to find an AED. An AED is both sophisticated and easy to use, providing lifesaving power in a user-friendly device. This makes the device useful for people who have no experience operating an AED and allows successful use in stressful scenarios. However, proper use of an AED is very important. The purpose of defibrillation is to "reset the electrical systems of the heart allowing a normal rhythm a chance to return."

CRITERIA FOR AED USE

  • No response after shaking and shouting
  • Not breathing or ineffective breathing
  • No carotid artery pulse detected

AED STEPS FOR INFANTS & CHILDREN


  1. Retrieve the AED

    (Fig. 1)
    • Open the case
    • Turn on the AED
  2. Expose the victim's chest

    (Fig. 2)
    • If wet, dry chest
    • Remove medication patches
  3. Open the Pediatric AED pads

    (Fig. 3)
    If pediatric pads not available use adult pads. Ensure pads do not touch.
    • Peel off backing
    • Check for pacemaker or defibrillator if present do not apply patches over the device
  4. Apply the pads

    (Fig. 4)
    • Upper right chest above breast
    • Lower left chest below armpit

  • If the AED is not working properly, continue giving CPR. Do NOT waste excessive time troubleshooting the AED. CPR always comes FIRST–AEDs are supplemental.
  • Do NOT use AED in water.
  1. Ensure wires are attached to AED box

    (Fig. 5)
  2. Move away from the victim

    (Fig. 6)
    • Stop CPR
    • Instruct others not to touch victim
  3. AED analyzes the rhythm

  4. Message "Check Electrodes"

    • Ensure electrodes make good contact
  5. Message "Shock"

    • Ensure electrodes make good contact
  6. Resume CPR for 2 minutes

    (Fig. 7)
  7. Repeat cycle

2010 AHA GUIDELINES FOR DEFIBRILLATION

Initial dose should be 2 to 4 J/kg (4 J/kg for refractory VF). Ideal energy levels yet to be determined.

2010 AHA GUIDELINES FOR AED USE

For 1-8 year olds, an AED with a pediatric dose to attenuator system should be used (if available). For infants under 1 year old, manual defibrillation is preferred. If neither pediatric dose attenuator or manual defibrillator available, a standard adult AED may be used.
