If your in nursing school
now (you don't have any credentials, which is why I'm thinking student) Ask your instructor if you can spend a day in the PACU.
We have second semester students that follow a patient from pre-op, to the OR, PACU and then back to SDS for Level II. The third semester students stay a day in the PACU and we show them how to do jaw thrust, chin tilts, assess airways and give them a bit of practice.
That shows you the day, but if your interested in the PACU, ask all the nurses there why they choose the unit and thier pros and cons. I did that on every unit I did clinicals on as a student, opened my eyes to lots of things I'd have never considered otherwise.
