Hi!
I did a unit month this spring and actually really loved it. I wanted to do one before I actually had real responsibility in July. I found that it wasn't much different from regular medicine services except that everything gets done MUCH faster, so you have to be on top of things, but you usually have fewer patients to focus on. And pretty much everyone is on a vent. The great part is that you are all on one unit together--the consultants come there and you can stop them and talk to them (no endless chart checking), x-rays results are called to you, you don't have to track down the nurses (and the nurses are usually very helpful). I learned a TON about ventilators and electrolytes. It was one of the best months I had overall in med school, learning wise. Don't worry too much and feel glad that it's not you running the codes just yet. 🙂
