The G3 was the AED that made Rescue Ready self-testing famous. The G5 is its successor same operational simplicity, but with substantially upgraded capabilities and the long-term parts and support story the G3 no longer offers.
For most buyers, the G5 is the right choice same operational simplicity, real-time CPR feedback that increases the quality of rescues, IP55 ruggedization that broadens deployment options, and active manufacturer support for the foreseeable future. The refurbished G3 remains a legitimate budget option for buyers who already operate G3 fleets or who specifically need the lowest-cost Powerheart available.
Intellisense CPR — Real-Time Coaching During Compressions
When paired with the optional Intellisense ICPR pads, the G5 monitors the rescuer's chest compression depth and rate in real time and delivers corrective audio and text prompts whenever compressions fall outside the American Heart Association's recommended parameters. This is the same kind of real-time CPR coaching that's standard equipment on EMS-grade defibrillators — brought into a public-access AED platform.
Why this matters: AHA studies consistently show that high-quality CPR (correct depth, correct rate, minimal pauses) more than doubles cardiac arrest survival rates compared to inadequate CPR. ICPR isn't a marketing feature — it's a feedback loop that materially changes the rescue outcome when a layperson is performing compressions under stress.
Rescue Ready Self-TestingThe same daily, weekly, and monthly automated self-test system that made the Powerheart line one of the most widely deployed AEDs in the U.S. Status visible at a glance without powering the unit on.
IP55 RatedDust ingress protected and water spray resistant — designed for indoor or sheltered outdoor environments. Suitable for industrial floors, athletic facilities, outdoor venues, and high-humidity locations.
Dual-Language ToggleOne button switches the AED between two preset languages (typically English and Spanish) during a rescue. Critical for bilingual workplaces, hospitality settings, and diverse communities.
Non-Polarized Intellisense PadsUnlike polarized pads that must be placed in specific chest positions, the G5's pads work in either location. Eliminates a common point of confusion during a high-stress rescue.
RescueCoach Voice PromptsUser-paced voice and on-screen text guidance that advances based on the rescuer's actions rather than running on a fixed timer. Adapts to slower or faster responders.
Variable Escalating EnergyIntellisense technology adjusts shock energy from 95J up to 354J based on the patient's transthoracic impedance. Higher peak energy than many competing AEDs in this class.
Military-Tested DurabilityTested to MIL-STD-810G military shock and vibration standards. Standby temperature range from -22°F to 158°F handles vehicle storage and seasonal extremes.
90 Min USB Data DownloadPost-rescue data downloads via USB cable or USB memory stick — no proprietary cradle, no specialty software hardware. Useful for EMS handoff documentation and program QA review.
Customizable Rescue ProtocolsShock and CPR protocols can be adjusted by qualified clinicians to match local medical-direction preferences or to update for changes in AHA resuscitation guidelines.
