The Cardiac Science Powerheart G3 Automated External Defibrillator (AED), now discontinued, was designed to provide lifesaving assistance during a Sudden Cardiac Arrest (SCA). Known for its intuitive design and clear voice prompts, the G3 AED enabled responders to act quickly and effectively, even without prior training. Although the G3 is no longer in production, existing units continue to serve as reliable tools in emergency situations, supported by available service and accessories.

For those looking for current models, the Powerheart G5 AED continues this legacy with advanced features that enhance usability and effectiveness in emergencies. Like the G3, the Powerheart G5 is designed to maximise survival chances during SCA with its user-friendly operation and comprehensive guidance system.

This guide provides insights on how to utilise both the G3 and G5 defibrillators during SCA emergencies, ensuring that responders can make the most of these critical tools to save lives.

 

Preparing to Use the Powerheart AED

1. Assess the Situation

• Check Responsiveness: Gently shake the casualty and ask if they are okay.
• Look for Normal Breathing: If the casualty is not breathing normally or at all, begin CPR and prepare the AED.

2. Call Emergency Services

• Dial 999 and inform the operator of the situation. Provide the location and condition of the casualty.

3. Retrieve the AED

• If available, locate and retrieve the Powerheart AED. Bring it directly to the casualty.

 

Using the Powerheart G3 and G5 Defibrillator

1. Turn On the AED

• Press the power button to turn on the device. The AED will provide clear, step-by-step voice prompts to guide you through the process.

2. Prepare the Casualty

• Ensure the casualty’s chest is exposed and dry.
• Use the razor provided in the AED kit to shave any excessive chest hair where the pads will be applied.

3. Apply the Pads

• Open the electrode pad packaging.
• Place the Pads:
  For adults: Place one pad on the upper right chest and the other on the lower left chest, below the armpit.
  For children under 8 years old or weighing less than 25kg, use paediatric pads and follow the same placement guidelines.

 

Following the AED’s Instructions

1. Analysis of Heart Rhythm

• The Powerheart G3 and G5 AED will automatically analyse the casualty’s heart rhythm to determine if a shock is needed. Do not touch the casualty during this analysis.

2. Shock Delivery

• If a shock is required, the AED will advise you to press the orange shock button.
• Ensure no one is touching the casualty before delivering the shock.

3. Continue CPR if Necessary

• After the shock, the AED will prompt you to perform CPR if needed. Follow the prompts to deliver high-quality chest compressions and rescue breaths.
• The AED will reanalyse the heart rhythm periodically and advise further action as needed.

After Using the AED

1. Monitor the Casualty

• Continue CPR and follow the AED’s prompts until emergency medical services arrive and take over.

2. Replace Used Components

• After the incident, replace the electrode pads with a new set. Inspect the battery to ensure it still has sufficient charge and replace it if necessary.
  

Why the Powerheart AED Is Effective
