Presentation by Paul Rasmusson and Henrik Skredsvik outlines the critical role of operating room (OR) ventilation in reducing surgical site infections (SSIs), details three primary ventilation methods: Turbulent Mixing Ventilation (TMV), Laminar/Unidirectional Airflow (LAF/UDAF), and Temperature-Controlled Airflow (TcAF). It highlights Avidicare’s „Opragon” system, a TcAF solution designed to create ultra-clean air by using gravity-driven downward airflow. A significant portion of the material focuses on the practical challenges of implementing these systems, including architectural limitations, budget constraints, and the complex needs of various stakeholders. It also provides a detailed case study of a hybrid OR project, tracking the process from initial design and 3D modeling to construction and final commissioning tests.
