DualShock Sync — Double Sequential Defibrillation Coordination Kit

A shock-synchronization trigger box with adapter cables that links any two monitor/defibrillators, letting EMS and ED teams deliver the newly recommended double-shock treatment for stubborn ventricular fibrillation with one trigger press instead of improvised hand-timing. Bundled with a dual pad-placement card, a one-page escalation protocol, and a crew in-service scenario.
