Depends on the unit and type of chamber. At the hospital I did this at, I was an ICU nurse who did on-call dives as required (either iCU patients or divers). It would be an advantage that you're a diver in that you'd understand the language. Disadvantage in that you can't dive (water) within a certain timeframe of diving (work).
Most of the caseload at our large multiplace chamber was wound care, diabetic ulcers etc 9-5, then bent divers or ICU patients out of hours. I don't think I could have done this fulltime (too many wound dressings etc) but it was interesting to do part time.
