Join the Ambulance Victoria ‘Good Sam’ register. Ambulance Victoria is maintaining a register of defibrillators so their ‘Good Sam’ responders can access this life-saving device faster than waiting for an ambulance. Every minute that CPR and defibrillation are delayed reduces the person’s chance of survival by 10%. A fast response can make the difference between life and death. AED Authority encourages every organisation with a defibrillator to register with Ambulance Victoria – just go to their website
