New report suggests the incidence of out-of-hospital cardiac arrest is 326,200 per year. With 300 million US inhabitants it comes to roughly 1 in 1000. So when 40 people live on one floor there is 1 incident in 25 years. The chance that it happens at home is maybe half the time, and again that someone witnesses it another half the time,so once in 100 years is the probability that the defibrillator on a floor may be used - if the building still is standing then. Keep pouring laws on us  ! How about a law on yourselves fixing shameful roads?
