§482.51(a)(3) - Qualified registered nurses may perform circulating duties in the operating
room. In accordance with applicable State laws and approved medical staff policies and
procedures, LPNs and surgical technologists may assist in circulatory duties under the
supervision of a qualified registered nurse who is immediately available to respond to
emergencies.
Interpretive Guidelines §482.51(a)(3)
The circulating nurse must be an RN. An LPN or surgical technologist may assist an RN in
carrying out circulatory duties (in accordance with applicable State laws and medical-staff
approved hospital policy) but the LPN or surgical technologist must be under the supervision of
the circulating RN who is in the operating suite and who is available to immediately and
physically respond/intervene to provide necessary interventions in emergencies. The supervising
RN would not be considered immediately available if the RN was located outside the operating
suite or engaged in other activities/duties which prevent the RN from immediately intervening
and assuming whatever circulating activities/duties that were being provided by the LPN or
surgical technologist. The hospital, in accordance with State law and acceptable standards of
practice, must establish the qualifications required for RNs who perform circulating duties and
LPNs and surgical technologists who assist with circulating duties.
Survey Procedures §482.51(a)(3)
• If LPNs and surgical technologists (STs) are assisting with circulating duties, verify that
they do so in accordance with applicable State laws and medical-staff approved policies
and procedures.
• Verify in situations where LPNs and STs are permitted to assist with circulating duties
that a qualified RN supervisor is immediately available to respond to emergencies.
• Verify that RNs working as circulating nurses are working in accordance with applicable
State laws and medical-staff approved policies and procedures.
