Background: The OR(operating room) should provide an optimum environment that is safe for the patient and the working personnel. The air ventilation system of OR has been studied to decrease the contamination of air. We investigated the flow and contamination of the air in OR at our hospital.
Method: Cultures in OR were made and the number of bacteria and fungi were calculated. A two-dimensional model for the cross-section of an operation room is developed for the CFD (computational fluid dynamics) analysis. The characteristics of air flow in the empty operation room and in the occupied operation room are calculated by using a CFD program.
Results: The current air ventilation system of our hospital does not deliver the clean air to the operating site efficiently in occupied OR.
Conclusions: We suggested a new location of air ventilation system which improves air venting with little increase of the cost of equipment.
