Background: For many years, surgical operation theatres have been provided with some form of ventilation equipment. Airborne bacteria in an operating room can come from sour­ces outside the room. From the outside sources, air in hospital wards and cor­ri­­dors is often con­­­taminated with pathogenic bacteria and may be sucked into the ope­ra­ting room by ven­tilation systems depending entirely on exhaust fans. This study ai­med to deter­mine the effect of ventilation on bacterial carrier particles in the ope­ra­tion theatre room at Cipayung Hospi­tal, Jakarta.

Subjects and Method: This was an experimental study conducted at the operation theatre room in Cipayung Hospital, Jakarta. The operation room had 90 m2 capacity with inlet re­gion on the floor and outlet region on the roof. The dependent variable was Pro­­tracted Bacte­ri­al Bron­chi­tis (PBB). The independent variable was Region of Interest (RoI). The data was mea­sured and analyzed by Compu­ta­­tional Fluid Dynamic (CFD) and visual me­thod.

Results: RoI of the patients was different in minimum air flow condition (y’= 0.47), me­­dium flow condition (y’= 0.32), and maximum air flow condition (y’= 0.17). RoI of the health workers was different in minimum air flow condition (y’= 0.73), medium air flow con­dition (y’= 0.43), and maximum air flow condition (y’= 0.26). RoI of dead zone was different in mi­ni­mum air flow condition (y’= 0.67), medium airflow condition (y’= 0.38), and maxi­mum air flow condition (y’= 0.23). RoI of the health workers had the high­est potential of PBB.

Conclusion: Region of Interest of the health workers has the highest potential of Prot­ra­c­ted Bacterial Bronchitis (PBB).
