Diverse Automatic External Defibrillators (AEDs) and Their Advanced Capabilities

Overview of AED Types

Despite numerous brands, AEDs can be broadly categorized into three main types, each with unique functionalities.

Semi-Automatic AEDs

Example: HeartSine 350. These AEDs require a manual shock delivery, indicated by a flashing button.

Automatic AEDs

Example: HeartSine 360. These AEDs automatically deliver a shock after a countdown, eliminating the need for a manual button press.

CPR-Assist AEDs

Example: HeartSine 500. These AEDs offer real-time feedback on CPR quality, aiding in effective resuscitation.

Gateway Unit: Enhancing AED Functionality

A unique addition to AEDs is the gateway unit, which enhances the unit's functionality with Wi-Fi connectivity.

Benefits of Gateway Units

  • Allows remote monitoring of AED status.
  • Provides alerts for pad replacement and unit checks.
  • Facilitates easy data transfer and management.

Choosing the Right AED

Selecting an AED depends on your specific needs. Consider whether automatic or manual shock delivery is preferable and if CPR feedback would be beneficial.


Understanding the different types of AEDs and their advanced features is crucial for effective emergency response and saving lives.
