    Sammanfattning : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. LÄS MER

    Sammanfattning : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. LÄS MER

  4. 4. Potential of Ventilation Radiators : Performance evaluation by numerical, analytical and experimental means

    Författare :Jonn Are Myhren; Sture Holmberg; Per Olaf Tjelflaat; KTH; []

    Sammanfattning : Energy consumption for heating and ventilation of buildings is still in 2011considered far too high, but there are many ways to save energy and construct lowenergy buildings that have not been fully utilised. This doctoral thesis has focused onone of these - low temperature heating systems. LÄS MER

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

    Författare :Pedro Gandra; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; airborne bacteria-carrying particles; microbial source strength; surgical clothing system; room air distribution system; Keywords: Ultraclean operating room;

    Sammanfattning : 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. LÄS MER
