What is it?

Cardiac Science’s Powerheart® AED G3, G3 Plus, and G5 are public access automatic external defibrillators AEDs. They are portable, battery operated, self-testing units used to diagnose and treat life-threatening ventricular arrhythmias in patients who are unresponsive and not breathing normally. There are three (3) models and related accessories: Powerheart® AED G3, Powerheart® AED G3 Plus, and Powerheart® AED G5.

How does it work?

Cardiac Science’s Powerheart® AED G3, G3 Plus, and G5 use two (2) multifunction defibrillation electrodes, placed on the patient’s chest, to acquire a patient’s electrocardiogram (ECG). Both adult and pediatric pads are available for each model. This device uses an ECG analysis algorithm to determine whether a victim has a shockable rhythm and advises a shock when appropriate. The user interface includes voice and text to guide the user through the rescue process to include shock delivery and/or cardiopulmonary resuscitation (CPR). The devices incorporate an audible metronome or voice prompt to guide the user as to the correct rate at which chest compressions should be administered. The G5 is available with an optional CPR device that provides four (4) distinct corrective CPR prompts to aid a trained rescuer and provides compression rate and depth performance feedback through audio and text prompting. If a defibrillation shock is required, the device will deliver a biphasic, impedance compensating, truncated exponential shock waveform to the patient through the multifunction defibrillator electrodes.

When is it used?

The Powerheart® AED G3, Powerheart® AED G3 Plus, and Powerheart® AED G5 are indicated for emergency treatment of victims exhibiting symptoms of sudden cardiac arrest who are:

  • unresponsive,
  • not breathing normally, and
  • without pulse.

When the patient is a child or infant up to 8 years of age, or up to 55 lbs. (25kg), the device should be used with the Intellisense™ Defibrillation Pad – Pediatric. The therapy should not be delayed to determine the patient's exact age or weight.

The Powerheart® AED G3, Powerheart® AED G3 Plus, and Powerheart® AED G5 are intended to be used by personnel who have been trained in its operation.

When Powerheart® AED G5 is used with the optional Intellisense™ Defibrillation Pad – ICPR, the device offers CPR performance feedback to aid a trained rescuer by providing compression rate and depth performance feedback through audio prompting. The Intellisense™ Defibrillation Pad – ICPR is indicated-for use on cardiac arrest patients 8 years of age or older, or who weigh more than 25 kg (55 lbs.).

What will it accomplish?

What will it accomplish? The benefit of early defibrillation therapy is survival of patients in cardiac arrest. The time from collapse to defibrillation is critical in patient survival. For every minute that passes between collapse and defibrillation, survival rates from sudden cardiac arrest decrease by 7-10%. Use of the Powerheart® AED G3, G3 Plus, and G5 can reduce the time in cardiac arrest and increase the chance of survival.

Potential adverse effects for AEDs include inappropriate shock, failure to identify shockable arrhythmias, failure to resuscitate, skin burns around the electrode placement area, interaction with pacemakers, myocardial damage, and bystander shock from patient contact during a treatment event.

When should it not be used?

The Powerheart® AED G3, G3 Plus, and G5 should not be used when a patient is conscious or breathing normally.
