This enables the device to exceed the American Heart Association performance recommendations, giving the user confidence the correct therapy is being delivered. The Lifeline AED defibrillator uses advanced biphasic technology — including the most studied biphasic shock waveform — and automatically adjusts the shock delivery to the person’s individual needs. For first response professionals like police, fire and EMS, the Lifeline AED is standard equipment. For schools, offices, stores, malls, factories, and public places, it’s becoming as vital as the fire extinguisher.
