(a) “Circulating nurse” means a registered nurse who is responsible for coordinating the nursing care and safety needs of the patient in the operating room and who also meets the needs of operating room team members during surgery.

(b) “Type I ambulatory surgical center” means a licensed health care facility for the performance of outpatient surgical procedures including, but not limited to, cholesystectomies, tonsillectomies or urological procedures, involving general anesthesia or a relatively high infection control consideration.

(2)(a) The duties of a circulating nurse performed in an operating room of a Type I ambulatory surgical center or a hospital shall be performed by a registered nurse licensed under ORS 678.010 to 678.410.

(b) In any case requiring anesthesia or conscious sedation, a circulating nurse shall be assigned to, and present in, an operating room for the duration of the surgical procedure unless it becomes necessary for the circulating nurse to leave the operating room as part of the surgical procedure. While assigned to a surgical procedure, a circulating nurse may not be assigned to any other patient or procedure.

(c) Nothing in this section precludes a circulating nurse from being relieved during a surgical procedure by another circulating nurse assigned to continue the surgical procedure.
