🛑 Quick Summary:
Cardiac Science Powerheart G3 AEDs utilize non-polarized defibrillation pads, meaning either pad can be placed in either position on the patient’s chest. Adult pads (Part 9131-001) are standard for patients 8 years or older (over 55 lbs). Pediatric pads (Part 9730-002) feature built-in energy attenuation for infants and children under 8 years of age (under 55 lbs). Both carry a strict 2-year shelf life from the date of manufacture.
Cardiac Science Powerheart G3 Electrode Pad Specifications
Defibrillation electrodes are critical consumables. The conductive hydrogel breaks down over time, compromising rhythm analysis and shock delivery. Use the table below to verify exact model compatibility and specifications:
| Pad Type | Part Number | Patient Profile | Shelf Life |
|---|---|---|---|
| Adult Intellisense Pads | 9131-001 | Age 8+ / Over 55 lbs (25 kg) | 2 Years |
| Pediatric Attenuated Pads | 9730-002 | Age under 8 / Under 55 lbs (25 kg) | 2 Years |

Key Technical Features of Powerheart G3 Pads
1. Non-Polarized Electrode Design
Unlike many AED models that require specific placement of the apex and sternum pads, Cardiac Science 9131-001 adult pads are completely non-polarized. In a high-stress rescue scenario, either pad can be placed on the upper-right chest or lower-left rib cage. This eliminates placement hesitation and accelerates rescue response times.
2. Pre-Connected Storage & Daily Self-Testing
Powerheart G3 pads connect directly to the unit while stored under the lid. The G3’s patented Rescue Ready® self-test system verifies the presence and electrical integrity of the electrode pads daily. If the pad gel is degraded, the seal is broken, or the connector is loose, the AED’s status indicator turns red and emits an audible chirp.
3. Power Supply Synergy
Defibrillation pads cannot function without adequate system voltage. The AED relies on its primary lithium power pack to conduct its internal circuit, capacitor charge, and pad impedance tests.

Inspection, Expiration, and Replacement Protocol
- Verify Expiration Date: Check the expiration date printed on the front of the sealed foil package. Pads must be replaced on or before this date to ensure the conductive gel remains moist and effective.
- Maintain Hermetic Seal: Never open the foil packaging during routine facility checks. Exposing the hydrogel to air causes it to dry out rapidly, rendering the pads ineffective during a cardiac arrest event.
- Keep a Spare Set on Hand: Safety compliance standards recommend keeping one primary set pre-connected inside the AED and a secondary set in the AED carry case or wall cabinet.
Frequently Asked Questions (FAQ)
Q: Can I use Adult 9131-001 pads on a child if pediatric pads are unavailable?
A: Yes. The American Heart Association (AHA) guidelines state that if pediatric-specific attenuated pads (9730-002) are unavailable during a pediatric cardiac arrest, standard adult pads should be used. Place one pad on the center of the chest and the other on the center of the back (anterior-posterior placement) to prevent the pads from touching.
Q: Why is my Powerheart G3 beeping and saying “Pads Expired”?
A: The G3 AED tracks pad connection status and self-test impedance. When pads reach their expiration date or fail internal continuity tests due to dried hydrogel, the unit alerts the user. Replace the pad pack with part 9131-001 immediately to restore the green Rescue Ready status.
Q: Are Powerheart G3 pads compatible with the Powerheart G5?
A: No. Powerheart G3 pads (9131-001) use a connector specific to the G3 family (9300 and 9390 series). They cannot be used with the Powerheart G5, which uses orange Intellisense pads engineered for the G5 platform.
