You're right, we have medics on every call, sometimes 3-4 medics. Most of our call types are ALS (cookbook EMD and CYA up-triage), and every ALS call gets an ALS engine. I don't see how anyone can learn, or get better as a paramedic when most of our calls are non-acute, minor issues, or monitor/IV jobs ate best. I'm lucky if I run one cardiac arrest a month, or do anything past a 12-lead and an IV on 90% of our patients. I used to work in the NYC 911 system. The protocols were very restrictive, probably due to there being numerous hospitals and privates working with the FDNY, but at least it was tiered, and we only responded to ALS calls. No board and collar jobs, injuries, sick jobs, EDP's, drunks, postictal Sz, etc. I learned 90% of what I know from the three years as an EMT, and two as a medic before I left the city. These last five years have been spent basically learning how to slow down to the speed of the other people working on our typical slow paced 6-7 person bum rush into each patient's house. The idea is if we have 2-3 medics on the scene, one of us should know what we're doing.
