SDN Members don't see this ad. (About Ads) For those of you doing procedures in the office, how is such a system set up. You'd have to have a pre/post procedure area. If you have a 3-4 bay holding area, plus 1-2 procedure rooms, how is this any different than a small ASC? What kind of regulatory/accreditation requirements are there? Also, in such a system, are you using RNs or CRNAs for sedation. Thanks.
