When I started in Melbourne Australia in 1997, I was an Ambulance Officer (EMT-, I was fortunate enough to be posted on the outskirts of town, were we had 15-20minute transport times and at least 15 minutes before the Mobile Intensive Care Para's (MICA) turned up. In Melbourne, they duel respond MICA to all Code 1 (Cardiac, SOB, MVA, Trauma), so you had you butt hanging out trying to get through your basic care before they turned up. If your BLS, O2, Obs, Monitor, Pulse Ox, etc etc wasn't done, they would write you up, regardless how green you were. These guys were feared by all students on the road.
In the inner city this happened as well, except you had MICA chasing you up the road and when you got there they would give you a rocket for not getting you BLS done in 90 secs. Crazy Stuff.
By the time I did MICA, things have changed some what. I always say to the guys, take your time or you will one day miss something so obvious you will kick yourself for weeks over it.
But there is more...these MICA guys would turn out to a call, single truck response, and if it wasn't an Intensive Care job, they would call control and get a AO car to come and transport so they were not tied up doing shite.
Glad I have moved on from there!!
