How often should the OR ventilation system be tested and maintained?

• A. Weekly checks.
• B. Per facility policy and manufacturer guidance; typically regular preventive maintenance with periodic certification; annual checks.
• C. Only when a problem is reported.
• D. Never require maintenance.

Answer: (B)

Maintaining a safe operating room environment hinges on keeping the ventilation system functioning as designed. The system must be routinely tested and serviced to verify that airflow, filtration, and pressure relationships meet specifications, and that components like filters, fans, and ducts are in good condition. The best practice is to schedule maintenance according to both the facility policy and the manufacturer's guidelines, combining regular preventive maintenance with periodic certification by qualified personnel, typically including annual checks. This approach ensures ongoing performance, catches small changes before they affect sterility or patient safety, and provides documented proof of compliance. Regular proactive maintenance is preferred over waiting for a problem, and maintenance should never be neglected or considered optional.
