CNS in perioperative, plastics or hyperbaric oxygen?

I am looking to start an MSN CNS program soon and also looking at a job change. I have been at a ambulatory surgery center for 11 years and work in the office setting as well as pre-op and PACU. I also prepare and review pre-op charts. I also work PRN in the ED (not sure I'd like it FT).

I am thinking of applying for a position at a local hyperbaric oxygen facility (would be FT).

I would like to be able to incorporate my "working" knowledge into the CNS program and since acquiring my MSN is going to affect my long term/future employment possiblities, I thought I should take different specialties I am familiar with into consideration.

Are any of you out there CNS's practicing in perioperative or hyperbaric settings? And what are your responsibilities?

Thanks!
