The HeartSine Samaritan PAD 450P AED is one of the most technologically advanced AEDs on the market. The 450P is one of the most efficient AED Defibrillators on the market due to the SCOPE waveform, a new algorithm that uses more variables to ensure the correct amount of joules are used. This AED has the fastest deploy time of all AEDs currently on the market, even for an untrained individual, and has the potential to save a friend, loved one, or teammates life in an emergency situation.
