ASHE ALERT
Pressure relationship between operating rooms and other areas
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. ASHRAE 170 Table 7.1 does not specifically address the pressure relationship of the restricted area but does generally in Section 7.1.a.1, which requires that ventilation systems shall provide air movement that is generally from the clean to less clean areas. ORs, due to patient vulnerability, should be considered the cleanest areas within an OR suite while sterile storage, due to containing items that need to be protected from contamination, should be considered a cleaner area than the OR suite restricted area. ASHRAE issued a formal interpretation on this issue in May of 2013.

 

Recommendations:

  • Due to patient vulnerability, operating rooms should have a positive pressure relationship to adjacent areas.
  • Sterile storage areas should have positive pressure relationships to all adjacent areas except OR's
  • Restricted areas within a surgery suite should have positive pressure relationships to al areas except OR's and sterile storage rooms.
