Influence of Surgical Staff Movement on Airborne Particle Concentrations in Operating Rooms with Laminar and Mixing Ventilation [PDF]

open access: yesE3S Web of Conferences
Operating rooms (ORs) are critical environments where airborne contamination control is essential for reducing the risk of surgical site infections. Ventilation strategies typically rely on either laminar air flow (LAF) systems or mixed ventilation (MV).
