The surgeons and firefighters who worked on me all say the key item in surviving a Sudden Cardiac Arrest is the availability of a defibrillator within 2 or 3 minutes.

Public-access defibrillation with AEDs is being implemented in many countries with considerable financial implications.

In large cities traffic and access to building complexes are serious obstacles to SCA rescue vehicles. On-site AEDs and elevators are a lasting and obvious solution.
