When should a patient be transported via helicopter? What are the criteria for this type of transport?
Some of the places I'm familiar with have drive times of 60 minutes or more to the nearest hospital, and 2-3 hours to the nearest trauma center. Those places have flight times of about 10 minutes and 25 minutes respectively, because the helo can go OVER the terrain rather than having to follow the road...
Oh oh oh

I win.
If you are closer than an hour to a hospital, there is no real good reason to fly the patient. No unbiased study has shown significant benefit in the United States outside of extremely rural settings for scene response flights. The only thing guaranteed is profit for the helicopter companies and a steady supply of new names to go here: http://www.airmedicalmemorial.com/
