the list you had is pretty accurate. aside from vents and acid/base (interpreting ABG's), the management of sepsis, ARDS, DKA, drug overdoses, fulminant liver failure, GI bleeding, and coagulopathies is important - these are the most common things you'll probably see in the ICU. another thing is the organization of notes in most ICU's, which goes by organ system and takes a little practice. a final suggestion is use of pressors, ie which ones to use in different situations and the indications for starting pressors. cheers, ICU is often fast-paced but rewarding, it's good to get some experience before you're a resident 🙂.
