Automated External Defibrillation
Public Access Defibrillation CPR and defibrillation improve chance for survival from sudden cardiac death. Defibrillation can be provided by rescuers through the use of automated external defibrillators (AEDs). Public access defibrillation (PAD) laws promote the use of AEDs in public places. Food and Drug Administration (FDA) approved devices for the home.
How the Heart Works Heart is a muscle. Four chambers store blood. Pacemaker cells send electrical impulses; heart muscle contracts. Normal sinus rhythm
When Normal Electrical Activity Is Interrupted (1 of 2) Ventricular fibrillation (V-fib) –A common abnormal heart rhythm in cases of sudden cardiac arrest in adults –Chaotic electrical activity that causes loss of circulation From Arrhythmia Recognition: The Art of Interpretation, courtesy of Tomas B. Garcia, MD.
When Normal Electrical Activity Is Interrupted (2 of 2) Ventricular tachycardia (V-tach) –A common abnormal heart rhythm in cases of sudden cardiac arrest in adults –Very rapid electrical activity –Heart may be unable to pump blood effectively.

Care for Cardiac Arrest CPR is the initial care until defibrillator is available. V-fib and V-tach can be corrected with defibrillation, but time is critical. For every minute that defibrillation is delayed, victim’s chance for survival decreases by 7% to 10%. Provide CPR until defibrillator is available.
About AEDs (1 of 2) Analyzes the heart rhythm Determines and advises need to shock Delivers electrical shock to the victim in cardiac arrest Can reestablish heart rhythm that will generate a pulse
About AEDs (2 of 2) Common elements –On/off button –Cable and pads (electrodes) –Analysis capability –Defibrillation capability –Prompts to guide user –Battery operation for portability
Using an AED (1 of 2) Turn the unit on. Apply AED pads to bare, dry chest. Make sure cable is attached to the AED.
Using an AED (2 of 2) Stand clear and analyze the heart rhythm. Deliver a shock if indicated. Perform CPR for 2 minutes. Repeat analysis. Repeat shock and CPR as needed.
Special Considerations (1 of 2) Water –Remove victim from water. –Dry victim’s chest. Children/infants –Use pediatric pads if available. Medication patches –Remove patches and wipe skin.
Special Considerations (2 of 2) Implanted devices –Pacemakers and defibrillators –Avoid placing electrode pads over devices if possible.
AED Maintenance Preventive maintenance checks are recommended. AED automatically performs periodic self-tests. Check supplies, such as expiration dates on electrode pads and batteries.
AED Manufacturers Devices and supplies are available from different manufacturers. All devices function similarly.
