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

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.
