Executive Summary ASHE has heard reports of surveyors issuing findings regarding the pressure relationship of operating rooms (ORs) and sterile storage rooms and the restricted areas of operating suites. ASHRAE 170 Table 7.1 Design Parameters indicates that operating rooms (OR) and sterile storage are to have a positive pressure relationship to adjacent areas. The FGI Guidelines Section 2.2-3.3.1.1(4) requires that the surgical suite be divided into two designated areas. The restricted area of the OR suite is intended to support a high level of asepsis control.
