Cardiac Science G5 Semi-Automatic Defibrillator

The Cardiac Science G5 semi-automatic defibrillator is built for reliability, backed by an 8-year manufacturer's warranty. Designed for use by anyone, even those with no prior first aid training, the G5 delivers clear voice and text prompts that guide the rescuer step by step through CPR and defibrillation.

Featuring non-polarised adult pads that can be placed in either position on the patient, the Cardiac Science G5 semi-automatic defibrillator removes guesswork in an emergency. An optional iCPR device provides real-time feedback on compression rate and depth, helping rescuers deliver effective CPR with confidence.

With an IP55-rated enclosure, the G5 is highly resistant to dust and moisture, making it suitable for offices, schools, leisure centres, GP surgeries, village halls, construction sites and public buildings across the UK. The unit performs daily, weekly and monthly self-tests automatically, with LED indicators confirming readiness and remaining battery capacity at a glance.

The Cardiac Science G5 semi-automatic defibrillator meets UK Resuscitation Council guidelines and is a trusted choice for businesses looking to comply with first aid requirements set out by the HSE.
