Investigation of methods regarding the effectiveness of ventilation strategies in an operating room on the removal of airborne germs using tracer particles

In this study contaminant distribution in an operating room is evaluated experimentally to be able compare different ventilation concepts afterwards. Low-turbulent unidirectional (LAF) used study. Heated dummies are positioned around the table, which release tracer particles that surrogate airborne germs and measured critical areas for bacteria spread. Measurement results compared terms of degree protection as well local air quality index. It shown realistic arrangements limit usage protection. Also, low indices show recirculation appearing at table.
