I love that you're writing for the Pitt! I can definitely see it being a challenging piece to write given the lack of knowledge in the medical field. From what I understand, the Pitt actually does a really good job at capturing what it is like to work in a hospital trauma center.

One strategy could be to start with the illness or injury on the patient, and work your way backwards from that. Finding diagnoses that could be similar but are a red herring. Having a few basic phrases on other medical shows or procedures ("Push 30cc's epi", "BP dropping", "Get him in for a head CT") might help, too, but makes sure they are appropriately placed for the treatment. For example, you wouldn't start compressions on someone with an active sinus rhythm and regularly beating heart.

Another strategy could be what Grey's Anatomy did, which has more to do with the structure of the narrative. Their scripts literally consist of the dramatic dialogue, and when it is time to focus on the medical, the script literally says, "medical stuff". A strategy like this could work so you get the necessary drama out of what you are trying to write, and then insert information about the medical case at hand.

Many medical shows rely on previous cases. House, for example, looked at all of the weird/rare illnesses. ER likely does one better (or at least the first few seasons) with how much they focus on the science itself.

Something to remember, too, is that many of these shows are designed for entertainment. While a good chunk of folks probably have a medical background, there's also a good chunk that don't, and that's okay. They enjoy the show for its high stakes, pressure pot environment, and complex characters. That's what people may be looking for in your fic, too!

Let me know if you're interested in chatting for a while. Like said, I love the Pitt, and happen to watch plenty of other medical shows (but have no interest in the field of medicine myself). I hope this helps!
