Cardiac Science Powerheart G5 AED

Features

Two ways to deliver the shock

Both versions read the rhythm through the pads. The fully automatic G5 announces the shock, counts down and delivers it without a button. The semi-automatic G5 waits for the red button; if nobody presses it within 30 seconds, it disarms the charge and calls for CPR.

Harder, softer, faster, slower

The CPR feedback pads (XELAED002) carry a palm-sized device on a cable. It sits mid-chest under the rescuer's hands and measures each compression, so the G5 can say Press harder, Press softer, Press faster or Press slower while CPR is under way.

With the standard pads instead

The standard adult pads (XELAED001) deliver the same shocks and the same spoken steps, without measuring compressions. The feedback pads may also be used with the device left beside the patient, and that device must never be used on a child under 8 or under 55 lb.

Children 8 and under

Connect pediatric pads (XELAED003) for a child aged 8 or younger or weighing 25 kg (55 lb) or less. The G5 recognizes them and lowers its energy from the adult 95J to 354J range to 22J to 82J. Keep them beside the AED, not plugged in.

Pads that fit either way round

The two adult pads are identical and non-polarized, so a rescuer cannot swap them by mistake. The G5 knows which pad type is connected and when it expires, and that date shows through a window in the lid. Adult pads have a 24-month shelf life.

A battery that shows its charge

The Intellisense lithium battery is not rechargeable. It is rated for 4 years in standby or about 420 shocks. Green lights on its Smartgauge go out as it runs down, and a red light means replace it. ZOLL warranties it for 4 years from installation.

Tests itself on a schedule

Each day the G5 checks its battery, pads and circuits. Every 7 days it adds a partial charge of the shock circuit, and every 28 days a charge to full energy. If a test fails, the Rescue Ready indicator stays red and the unit beeps every 30 seconds.

Two languages and a rescue record

On this dual-language unit, a button switches every spoken and written prompt between English and Spanish at any point in the rescue; closing the lid sets it back. The G5 keeps up to 90 minutes of rescue data, which can be downloaded over USB.

What it takes to keep ready

Across the 8-year limited warranty, plan on new adult pads about every 2 years, a fresh Intellisense battery around year 4, and another set of pads after any rescue. Feedback pads cost more than the standard pair, so decide whether depth coaching matters to your site.

G5 or another model?

Choose the G5 for depth coaching plus a choice of automatic shock, mounted where it will stay. For a carry bag, the 2.4 lb HeartSine 450P coaches rate only. The ZOLL AED Plus and AED 3 also coach depth, through sensors built into their pads.
