An automated external defibrillator (AED) is a portable medical device that analyzes a person’s heart rhythm and can recognize whether or not the individual’s heart is experiencing an abnormal rhythm that requires a shock. 

But not all AEDs are the same! As you think about which AED is right for you, it’s important to consider different AED features and what they mean for you.

WiFi Capabilities

“In order to save more lives from sudden cardiac arrest, we must save time,” said Ryan Landon, Stryker’s Vice President and General Manager, Emergency Care Public Access upon the release of the LIFEPAK CR2 last year. “The LIFEPAK CR2 is designed to help rescuers provide higher quality CPR and to provide the fastest first shock when defibrillation is needed. Everything about it is designed to increase user confidence” (PR Newswire).

Wi-Fi connectivity also enables:

  • Remote analysis of device readiness
  • Remote analysis of device battery and pad life
  • Self-testing
  • Real-time alerts that indicate when the device is in use
  • Real-time communication with emergency responders

Dual Language

AEDs are incredibly easy to use and voice and text prompts make them even easier.

But what if English isn’t your first language? What if you, like an estimated 41 million US residents, or 13.5% of the population, speak Spanish at home? Then you’ll want to look for a dual language AED — like the Cardiac Science PowerHeart G5 or the Difebtech Lifeline View — for your school, office, or community organization. 

Water Resistance

Looking for a water-resistant AED? Take a look at the IP rating. The first number tells you how resistant your AED is against the penetration of solid objects. For the purposes of IP ratings, “solid objects” can include body parts, tools, and even particulates such as dust or soot. The second digit in an IP rating indicates the level of water protection.

For powerful water resistance, take a look at the HeartSine Samaritan PAD 350 or the HeartSine Samaritan PAD 450 with a rating of IP56.

Automatic vs. Semi-Automatic

“All AEDs automatically analyze the heart rhythm to determine if a shock is needed. However, there are two types of lay-user AED — fully automatic and semi-automatic. If a shock is needed, semiautomatic AEDs prompt rescuers to press a shock button. A fully automatic AED is designed to give a shock automatically” (OnebeatCPR). 

CPR Feedback

Many models offer some form of CPR feedback to guide rescuers through the process. The ZOLL AED Plus and the ZOLL AED Pro, for example, offer real-time CPR feedback to help rescuers perform high-quality CPR and to more effectively save lives. While only half of all sudden cardiac arrest (SCA) victims need defibrillation, all of them need effective CPR. Real CPR guides rescuers through CPR and even advises them to “push harder,” if necessary.
