I;m going to step in here quickly. I have worked in Israel, alongside 15- and 16- year old First Responders (note, they are NOT EMTs, can cannot be trained to that level until 18). Two first responders staff a normal BLS ambulance with one EMT/Driver. The EMT is responsible for stabilization on scene, and if it is anything major, calling ALS. For the normal BS/BLS, the FRs monitor vitals and patient condition en route, and complete the patient care documentation (and bill).
The teenage FRs are specifically chosen for their maturity and leadership abilities, they are not jus random kids off the street. Israel has a strong sense of community service, and this is one of many ways these kids give back to their community, this is a hoby, but considered a job for them.
One last note, when there is a call for a terror attack of any kind, the ambulance stops, and lets everyone under 18 off, then procedes to the scene. There is such a high percentage of the population that is trained to the EMT (+) level, they have more then enough personnel on scene, and dont want to risk injury to the teenagers.
I need to run now, but would be glad to comment on this further, either on-forum or in private.
