Session Abstract
BACKGROUND
Ventilation and airflow are crucial in operating rooms (OR) for controlling thermo-hygrometric conditions, providing gas removal, dilution of airborne contaminants and minimising the airborne transfer of pathogens (bacteria). In order to maintain a safe and comfortable environment for patients and staff, all of these considerations must be met and each of them has specific requirements. Therefore, for these requirements to be met efficiently, design engineers and operators must rely on various analysis (computational, analytical) and control methods (model-based) that provide the most reliable and detailed information as possible. In this symposium, we aim to bring together experts with complementary expertise in the field of indoor environment modelling (computational fluid dynamics), measurements, sensing and control applied to the operating-theatre environment. The symposium will enable cross-disciplinary interaction and group thinking to address some of the challenges of the OR of the future by reviewing existing approaches and proposing new methods. The chosen presentations will enable researchers to engage with various complementary topics providing (1) with improved understanding of the local influence of airflows on particles close to occupants, (2) improved quantification of the transient behaviour of the OR indoor environment (ORIE), including the fate of contaminants due to healthcare activities, (3) introduce to the methods of augmenting computer simulation with measured sensor data to enable a deeper understanding of the ORIE and thereby paving the way for a robust, adaptive and energy-efficient ventilation control system for the OR.
