I just finished the 8 day WFR course, so I am officially certified. In addition to all the classroom lectures we did a total of four simulations.
The third simulation was by far the worst because it included basically an overwhelming rush of patients in a very limited setting, with only 6 care providers. Fortunately I was designated as an assistant, and we were told to act as if we had no medical knowledge. The assistants were mainly just babysitting patients and doing patient carries in a Stokes Basket when needed. It was actually a bit hard to sit with a patient and have to pretend to not know how to help them.
The fourth simulation wasn't as bad, because we had roughly 45 care providers, probably more than the number of patients. The main thing about this simulation was just that it was supposed to be unexpected. They had initially set it up similar to the other simulations, with designated primaries, assistants, and patients. When we got to the side they tried to surprise us by telling us that the patients were already on scene, and we were all primaries (care providers). It wasn't that bad, considering that the change made it a lot easier. Since we hadn't really been told much about the scene we didn't have the opportunity to plan around it. The 'surprise' didn't really change much, so we were able to just roll with it.
This coming week is CD (Camp Director) training week, so I have another week of straight training to look forward to.
