Either some time has passed since RocketMedic's time at EMSA or Tulsa is just vastly different. But here's a little perspective from the other end of the turnpike:
The paramedic program is fast paced and takes eight months. It's done though Redlands Community College in El Reno but onsite in Tulsa and OKC with EMSA instructors. The guy in Tulsa goes heavy into A&P and seemingly takes teaching more seriously than a lot of certificate programs throughout the state. The buyout from the contract is relatively inexpensive and you're basically paid to be a student and work the odd shift. So far, the medics that have made it through the program are pretty good.
As for working here, the schedule has changed some. The shifts are still twelve hours but you'll alternate four and three day work weeks. Some shifts are weekday only, some weekends, and some alternate. The starting wage is also higher now to compensate for the loss of hours so you can expect to start around $11.30ish/hour as an EMT. Shifts are chosen based on seniority so you can kiss your weekends goodbye for the first year but that won't matter much if you make it into the paramedic course after six months. It's also worth mentioning that the max EMT pay is actually above the minimum paramedic pay and, for now, there are plenty of OT shifts and almost all of them are bonused at $350. That will probably stop once staffing is increased enough to cover all of the shifts they've added but it's pretty easy to get hired this year as a consequence.
The protocols really are hit and miss and yes you need a four lead, BP, and SpO2 before administering any meds but a halfway-decent partner will have that knocked out before you have anything drawn up. If you really feel it needs to be done now, you do the paperwork, so whether or not you throw yourself under the bus is up to you. Most people elect not to. The spinal immobilization protocol is slightly more lax now but is another thing that can be documented away in a lot of cases.
The main advantage to working at EMSA is that it fits a lot of experience into a short amount of time. The average number of calls per shifts has gone down with the larger numbers of ambulances being put on the street but there are still nights of 10 or more calls. And like RocketMedic already explained, the school you attend really isn't that important. The next agency you work at will be more concerned about your experience and you'll have plenty. It's true that their is some animosity towards EMSA medics for a certain better-than-everyone-else attitude we seem to exude (or so I've been told) but you'll be hard-pressed to find a service in Oklahoma that doesn't have at least one former EMSA employee on staff.
It's definitely not for most people but it's a wonderful stepping stone. If you do decide to apply here, don't mention you want to be a firefighter. Just my two cents.
