  1. Chapter 6AED

  2. Public Access Defibrillation • Sudden cardiac death is an unresolved health crisis. • CPR and defibrillation improve chance for survival. • Automated external defibrillators (AEDs) must be used in first few minutes following cardiac arrest. • Public access defibrillation (PAD) laws have helped make AEDs available.

  3. The Chain of Survival • Early access • Early CPR • Early defibrillation • Early advanced care

  4. The heart is a muscle. Four chambers coordinate blood flow Pacemaker cells emit electrical impulses; heart muscle contracts How the Heart Works

  5. When Normal Electrical Activity Is Interrupted (1 of 2) • Ventricular fibrillation (V-fib) • Most common abnormal heart rhythm in cases of sudden cardiac arrest in adults • Chaotic electrical activity that causes loss of circulation

  6. When Normal Electrical Activity Is Interrupted (2 of 2) • Ventricular tachycardia (V-tach) • Very rapid electrical activity • Heart may be unable to pump blood effectively

  7. Care for Cardiac Arrest • CPR must be started 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%. • CPR is initial care until defibrillator is available.

  8. About AEDs(1 of 2) • Electronic device that: • Analyzes the heart rhythm • Determines and advises need to shock • Delivers electrical shock to the victim in cardiac arrest • Reestablishes a heart rhythm that will generate a pulse

  9. About AEDs (2 of 2) • Common elements • On/off button • Cable and pads (electrodes) • Analysis capability • Defibrillation capability • Prompts to guide you • Battery operation for portability

  10. Turn the unit on. Apply AED pads to bare chest and the cable to the AED. Using an AED (1 of 2)

  11. Using an AED (2 of 2) • Stand clear and analyze the heart rhythm. • Deliver a shock if indicated. • Perform CPR for 2 minutes (five cycles). • Check victim and repeat analysis, shock, and CPR steps as needed.

  12. Water Remove victim from water Dry victim’s chest Children Medication patches Remove patches and wipe skin Special Considerations (1 of 2)

  13. Implanted devices Pacemakers and defibrillators Avoid placing electrode pads over devices. Special Considerations (2 of 2)

  14. AED Maintenance • Preventive maintenance checks are recommended by manufacturers. • The AED will automatically perform periodic self-tests, but it should be checked daily to ensure proper operation. • Check expiration and replacement dates on electrode pads and batteries.
