Comparison of operating room ventilation systems in the protection of the surgical site.

Author(s) : MEMARZADEH F., MANNING A. P.

Summary

The paper uses airflow modelling and particle-tracking methodologies to compare the risk of contaminant deposition on an operating room surgical site and back table for different ventilation systems. The type of particle considered was a squame, or skin scale, which is around 10 microns in size. Particles were released from three locations in the room, and tracked to determine whether they would impinge on either the surgical site or a back table. The results were tabulated so that the lowest percentage of impacts would indicate the most appropriate ventilation system. The results show that ventilation systems that provide laminar flow conditions are the best choice. A face velocity of around 0.15 to 0.18 m/s is sufficient from the laminar diffuser array, provided that the size of the diffuser array is appropriate.
