So, in LA County, your odds of getting sick patients are actually higher on IFT than 911. That holds true for most places. As a basic, you'll likely be exposed to legions of the fragile, sick and injured on IFT, and you'll be it....the expectation is that you 'manage' them as well as possible. 911 in LACo is pretty basic anyway, so it's not like you're going to be doing a whole lot as a private B in any event.
Long-term advice, you need to look outside of LA County. EMT at Hall, move north or out of state entirely, etc. Go somewhere where you can go to medic school and get better at your craft. If you want to do 911, quit limiting yourself to LACo. Come out to Texas. Here at Cypress Creek, you, as a brand-new Basic, can literally be the junior partner on a P/B team that runs all 911 in a metro area the size of Atlanta or Denver. Same certs, same experience, same training you've got, but while you're running dialysis or looking for 'experience' in reps, my partner is doing everything except literally pushing drugs and the like (because I am all about teaching people). Sinking King tubes, ventilating, suction, obtaining and seeing 12-leads, making decisions, etc? They're doing that, because my job as a medic isn't just patient care, it's professional development. Come move out somewhere where you can be more than a stretcher fetching van driver.
