ZOLL Stat-padz® are the fastest, easiest-to-use multi-function defibrillator electrodes and are optimized for emergency resuscitation situations. Unique ZOLL features save life-saving seconds and maximize efficacy: Preconnect™ saves critical application time. Speed Pack™ reduces cord tangles and fumbling. Anatomically correct diagrams facilitate proper pad placement. Improved polymer gel enhances lateral conductivity; results in less skin effects. Center energy feed distributes energy uniformly; reduces edge effect. Differentiated round front and rectangular back pads are diagrammed to facilitate proper pad placement. For compatibility with AED Plus® and AED Pro®, choose Stat padz II, with the same great features as the Stat-padz, but with a specially designed connector that works directly with the AEDs.
