Ok so I'm a nurse in Australia. I have been in the OR for 6 years & I love it. I'm intrigued as to how the OR is different compared to Australia.
We have 3 nurses to a OR for all cases. 2 are scrub/circulating nurses who will take turns in scrubbing throughout the day (we don't have techs). And the 3rd nurse is an anesthetic nurse who assists the anesthetist.
We also have OR tech who help position the patient, set up equipment and make sure all equipment is in the OR for the surgeon.
