Here, in the Netherlands, we have a network of civilian first responders, with people that will be alarmed by the 112 (for you Americans: that's the European version of 911) call center when a CPR request is near them. Also, we have a practical full cover over the country of AEDs. We have one against our front wall, accessible for everyone. In 1.5 years of time, I got two times a call that I was able to respond to, but our emergency services were already present when I arrived (by bike) on the location.
