There is no paramedic program in Belize that I know of. Starting one would take a huge amount of effort.
The math supports Dr. Tommy's position. Locals and many visitors aren't going to be able to pay for a helicopter trip to the city. Outfitting an EMS equiped helicopter is about $3,000,000+usd for a basic set up in a Long Ranger. Now add in pilots, nurse and maintenance costs. And lets not forget an operating certificate from civil aviation. The GOB is not going to pay towards a helicopter program.
Unfortunately the GOB didn't support the BATSUB issue. Goodbye equiped helicopter. But that's an entire new thread.
A samll set up in the Lions Poly Clinic would work. Dr. Danny at Ambergris Hope Clinic has a set up for operating.
The big issue is getting the first responders all on the same page, packaging the patient for transport to a recieving facility of some type and stabilizing, evaluating and then transporting to the city if needed.
