Background Without confirmation of the ventilation design conditions (typology and airflow
rate), the common practice of identifying unidirectional airflow (UDAF) systems as equivalent …

It is desirable to maintain a low bacterial count in the operating room air to prevent surgical
site infection. This can be achieved by ventilation or by all staff in the operating room wearing …

Background To prevent surgical site infection it is desirable to keep bacterial counts low in
the operating room air during orthopaedic surgery, especially prosthetic surgery. As the air-…

Today, clothing and clothing systems for cleanrooms are mainly tested with regard to
material properties such as particle generation, particle fi ltration, and resistance to wear. The …

of particle challenge test and visualization technique,” Proceedings of the Uth International …

The purpose of this presentation is to describe the theoretical relations for the dispersal of
airborne contaminants and to illustrate the validity of these equations occuring during factual …

This paper presents results from a comparative study of different impaction air samplers under
simulated operational conditions in a controlled environment. Furthermore measurements …

Background Lowering air-borne bacteria counts in the operating room is essential in
prevention of surgical site infections in orthopaedic joint replacement surgery. This is mainly …

Hazard Analyses and establishing of Critical Control Points (HACCP) using a method with
Limitation of Risks, known as the LR Method are described. This method has a concept …

… 2, we compare their results from two impaction air samplers, B with a d 50 value ≤2 μm,
and E with a d 50 value ≤15 μm (Table 1). Results from Sampler E had a mean concentration …
