The system integrates traditional Cardiopulmonary Resuscitation (CPR) with automated external defibrillation (AED) technology to improve survival rates during sudden cardiac arrest: CellAED® Device
(Note: If you were looking for a specific branded guide called "Opander CPR," this appears to be associated with spam or misleading online files often bundled with a personal defibrillator device named CellAED. For real emergencies, always follow the standard medical steps below.) 🚨 Step 1: Check the Scene and the Person Ensure safety: opander cpr
Research shows that for every 5 seconds of hands-off time (paused for rhythm analysis), survival drops by 10%. Opander reduces this by allowing the AED to charge while the rescuer continues compressing. The device instructs: "Continue compressions... Shock advised. Stand clear in 3...2...1... SHOCK. Resume compressions instantly." The device instructs: "Continue compressions

OC-CPR was the original method described in the 1960s before closed-chest CPR became standard. It was abandoned not due to lack of efficacy but due to invasiveness and logistical difficulty.
