Understanding Automatic External Defibrillators (AEDs)

1. What is an AED?

An AED, or automatic external defibrillator, explained.

There is a common misconception that AEDs restart the heart, but their role is to interrupt abnormal heart activity.

2. AEDs and Heart Function

Understanding how AEDs work to restore a normal heart rhythm.

  • Electric activity in the heart can lead to abnormal twitching rather than a meaningful pulse.
  • An AED delivers a shock to interrupt this electric activity, allowing the heart's natural pacemakers to restart it in a normal rhythm.
  • AEDs advise a shock only when detecting specific shockable rhythms, such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT).

3. Types of AED Units

Exploring different AED models and their operation.

  • Semi-automatic AEDs require manual activation of the shock button when advised.
  • Automatic AEDs initiate shocks automatically when necessary.
