Numerical Analysis of Operating Theatre Ventilationa

Surgical Site Infection (SSI) is one of the most important and potentially protectable source leads to increase the remedy duration and even a patient’s eath. According to the literatures, the primary source of SSI is the flakes or squame which are released from the exposed skin of surgical staff or patient. Proper ventilation strategy is well known as the most effective way to control microbiological agents responsible for SSI.In the recent decade CFD, as a powerful engineering tool, has been widely used to study the airflow and airborne contaminants through operating rooms.Previous studies proposed that interruptive effect of surgical lights is the most critical phenomena which may affect the air quality around surgical wound.However, it seems that it still needs more investigations, especially in non-standard ORs. In this research the effect of surgical luminaries has been studied using CFD technique in both standard and non-standard operating theatres.
