I have to agree with the previous comments. As a CVOR RN, I not only circulate, but scrub and assist the surgeon in the case. Many hospitals are now understanding the advantage of hiring RNs who can both circulate and scrub in the CVOR setting (getting more bang for the buck). Also, depending on the size of the team and program, there is a fair amount of on-call (call-back) that goes along with being a CVOR RN.
