  5. 3. Practical Safety Ventilation in Ultraclean Air Operating Rooms

    Author : Pedro Gandra; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne bacteria-carrying particles; microbial source strength; surgical clothing system; room air distribution system; Keywords: Ultraclean operating room;

    Abstract : PRACTICAL SAFETY VENTILATION IN   ULTRACLEAN AIR OPERATING ROOMS When planning new ultraclean air operating rooms, often the first question is which is the preferred room air distribution system and what system is the best to meet the requirements of microbiological air cleanliness. Today, in Sweden, the requirement is a target level of 5 CFU/m3during the design phase, in order to ensure that the level of ≤10 CFU/m3during infection prone surgery is maintained. READ MORE

  6. 4. System analysis of kitesurfing : Understanding performance and injury risk for on-water board sports

    Author : Lina Lundgren; Sofia Brorsson; Anna-Lisa Osvalder; Högskolan i Halmstad; []
