I am an operating Room nurse in a small community hospital. I am considering joining the Airforce, my recruiter told me the best chance ill have will be to go in as an O.R. nurse. The operating room is all the expeirence I have as a nurse. I am fine with joining as an O.R. nurse but I eventually want to change to the CCU or ICU. How hard is it to transition from an O.R. nurse to an CCU nurse and how long can it take? Can I recieve training to transition?
