ZOLL has developed a dedicated paediatric arrhythmia analysis algorithm that can distinguish shockable versus non-shockable pediatric rhythms. This algorithm detects whether paediatric or adult electrodes are connected and automatically adjusts the arrhythmia analysis processing for a child. This unique algorithm is available in the ZOLL AED Plus^® and AED Pro^®, as well as in the R Series^®.

The device can sense when paediatric electrodes are attached and switch from an adult to paediatric ECG analysis algorithm. Pedi-padz^® II electrodes are designed especially for use with the AED Plus and AED Pro, while the OneStep™ Pediatric Electrode works with the R Series to automatically lower the Joules setting to 50 Joules, preventing accidental overdose during defibrillation.
