This session has 3 papers: The first paper covers the investigation of the influence of the surgical operating theatre architecture design on the efficiency of the flow of air-conditioned supply to create sterile and comfort environment in the theatre. The present work is devoted to investigate the relation between airflow movement and air age and the operating room architecture. The second paper examines the effectiveness of a currently used Airborne Infection Isolation Room (AIIR) in protecting health-care workers (HCWs) from airborne-infectious (AI) exposure. The goal is to assess ventilation design to mitigate this exposure for the HCW. The research also compared HCW AI exposures within an AIIR and a traditional patient room, and assessed ventilation design options for the two rooms. The third paper analyzes the effect of mechanical parameters, especially the envelope leakage as it ranges from tight to effectively zero. When the room is sealed, or nearly sealed, mechanical coupling between air flows in and out of the room complicates control loop dynamics. Flow and pressure loops that are ordinarily almost independent become tightly coupled with the potential to destabilize one another.
