AED Defibrillation Pads | High-Energy Biphasic Discharge | TOP-RANK
Technical data for AED return electrodes. Evaluated for 360J pulse stability, 24-month impedance drift, and AAMI DF80 compliance. Compatible with Philips, Zoll, and Medtronic protocols.
Product Overview
These electrodes are the conductive return path for biphasic truncated exponential (BTE) waveforms used in external defibrillation and external pacing. They function as a high-current interface (up to 360J) between the defibrillator's output stage and the patient's thoracic cavity.
Key Features
Impedance Drift & Gel Aging Logic
Hydrogel is a water-based polymer. Over 24 months, water molecules migrate through the PET/AL/PE foil pouch. We measure the moisture vapor transmission rate (MVTR) of our packaging to ensure the out-of-bag impedance remains below 3 ohms at the end of the 2-year cycle. If the water content drops by 15%, the pad fails the AAMI DF80 discharge test.
Thermal Load Distribution (360J)
During a 360-joule shock, the energy must be distributed across the entire 135cm2 surface. We use computer-controlled etching for the foil substrate to avoid sharp corners or "islands" in the conductive path. This keeps the current density uniform and prevents the skin temperature from exceeding 45C during the discharge pulse.
Mechanical Stability Under CPR
Chest compressions create significant lateral force on the electrode. We tune the hydrogel cross-linking density to provide high shear resistance. The pad remains in full contact with the skin despite the 100-120 compressions per minute required by ACLS protocols.
Applications
- Public Access Defibrillation (PAD): Deployment in automated external units (AEDs) for standby use.
- Emergency Medical Services (EMS): High-frequency pacing and defibrillation in field environments.
- Hospital ICU/ER: Standby pacing for bradycardia and acute cardiac arrest management.
OEM & Private Label
We provide component-level manufacturing in China and Vietnam.
- Connector Integration: Compatibility testing available for Philips (Plug-and-Play), Zoll (Rectangular), and Medtronic (Quik-Combo) interfaces.
- Pouch Specifications: Custom printing of anatomical diagrams using medical-grade ink that resists alcohol-based cleaning agents.
Certifications
- Regulatory File: FDA 510(k) clearance, CE (MDR) certification, and UKCA.
- Factory Systems: MDSAP and ISO 13485.
- Batch Tracking: Each lot undergoes a simulated 360J discharge test. We log the post-shock impedance and visual check for foil pitting or gel charring.
FAQ
Q: Why does the machine alarm for "Pad Contact" with a fresh pouch?
A: This usually indicates an impedance mismatch between the gel and the specific AED calibration. If the gel has experienced thermal cycling during storage, the ionic concentration shifts. We recommend testing your AED's internal resistance sensitivity against our AAMI DF80 batch data.
Q: Can these pads be used for synchronized cardioversion?
A: Yes. The Ag/AgCl or high-purity foil layer allows for the ECG monitoring required to synchronize the shock with the R-wave.
