How to Tell If Your AED is Ready for Rescue: Powerheart G3 & G3 Pro


This is Blaire with Coro Medical, home of AED.US and today we’re going to go over how to tell if the Cardiac Science Powerheart G3 AED is rescue ready.

We always say the only thing worse than not having an AED is having one that doesn’t work. One of the main reasons an AED fails is because it was not properly maintained. AEDs are very easy to inspect and maintain. I’m going to show you just how easy it is to know if your Cardiac Science Powerheart G3 is rescue ready. The most important inspection tasks are to check the rescue ready status indicator and verify the electrode pads and batteries have not expired. Your AED performs a self-test daily weekly and monthly. The rescue ready indicator allows you to quickly see if it passed its self-test and is ready for use. It will also show an alert if a problem is found. This is why it’s important for you to conduct those regular inspections. On the Cardiac Science G3, the rescue ready indicator window is located on the handle. A green indicator means the AED is ready for use and a red indicator with an “X” means the AED requires attention or maintenance and is not rescue ready. One neat feature on this AED is the “X.” This is for anyone who is color blind.

Once a month, you’re going to do three things:

  1. Verify the rescue ready status indicator is green.
  2. Check the expiration date of your AED pads and battery. The pads have a two-year expiration and the battery has a four-year guarantee.
  3. Check the overall condition of the AED and note any deficiencies. You can log each monthly inspection on the check tag that we provide for free with each AED.
