CPR Stat Padz is a traditional two-piece electrode, while CPR-D-Padz is a one-piece design. Both provide ZOLL's Real CPR Help compression feedback, but the two-piece Stat Padz format gives an ALS responder more placement flexibility, both Anterior/Anterior and Anterior/Posterior, and this specific version adds See-Thru CPR for viewing cardiac electrical activity during active compressions. One reseller describes CPR Stat Padz as combining features of the CPR-D-Padz's feedback technology with the traditional two-piece Stat-Padz II form factor.
CPR-D-Padz, by contrast, is built specifically for the AED Plus and AED Pro, carries the longest shelf life among ZOLL's Real CPR Help electrodes (5 years), and does not support pacing or cardioversion, since it is not built for professional monitor-defibrillators the way this electrode is. See the ZOLL CPR-D-Padz product page for full detail.
