Chapter 4 Automated External Defibrillation
Automated External Defibrillator (AED) • An AED is an electronic device that analyzes the heart rhythm and, if necessary, delivers an electric shock, known as defibrillation, to the heart of the person in cardiac arrest. • What does this shock do? • A normal and healthy heart has its own pacemaker that regulates the heart beat. The shock stops all electrical activity of the heart so the pacemaker can take over again.
Common Elements • About AEDs: • Many different models exist. Follow the displays, controls, and options for the model you are using. • The AED enables first aid providers and other rescuers to deliver early defibrillation with only minimal training.
Using an AED • Turn on the AED. • Attach the pads to the person’s bare, dry chest, as shown on the pads.
Using an AED • Make sure no one is touching the person and say “Clear!” • Allow the AED to analyze the rhythm. • Follow the prompts. • The AED will either direct you to push the Shock button or to begin CPR.
Using an AED • Give 5 sets of CPR unless the person moves, begins to breathe, or wakes up. • Repeat Steps 3 and 4 until the person moves, begins to breathe, or wakes up.
