Ambulance Arrival Time Maps and Testing
So, since it is know that human brain begins dies in 5 minutes without oxygen, the timing of emergency help, and ambulance is critical to increasing survival rates. Not a new idea. The UK has been controlling for arrival times for a long time, and there are such maps (http://www.ambulanceresponsetimes.co.uk/) , but it would be important globally, and may help people at risk to decide where to live.
The response times are so important, that it would make sense to control for that with tests like in software development.
