2. 1. Ventilation Performance in Operating Rooms : A Numerical Assessment

   Author : Cong Wang; Sture Holmberg; Sasan Sadrizadeh; Anna Bogdan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating room ventilation; bacteria-carrying particles; laminar airflow; mixing ventilation; temperature-controlled airflow; computation fluid dynamics; Lagrangian particle tracking; Civil and Architectural Engineering; Byggvetenskap; Strömnings- och klimatteori; Fluid and Climate Theory;

   Abstract : 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. READ MORE

4. 2. A new generation of hospital operating room ventilation

   Author : Parastoo Sadeghian; Sasan Sadrizadeh; Catherine Noakes; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventilation systems; bacteria-carrying particles; airflow behaviour; operating room; computational fluid dynamics; surgical site infection; Ventilationssystem; bakteriebärande partiklar; luftflödesbeteende; operationsrum; numerisk strömningsmekanik; kirurgirelaterad infektion; Strömnings- och klimatteori; Fluid and Climate Theory;

   Abstract : Surgical site infection is responsible for 38 percent of reported infections after surgery. This infection increases mortality and treatment costs, and prolongs the hospitalization of patients. READ MORE

   Abstract : 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. READ MORE

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

   Author : Jonn Are Myhren; Sture Holmberg; Per Olaf Tjelflaat; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventilation radiator; thermal comfort; exhaust ventilation; CFD; energy saving; convection fin; low temperature heating; Building engineering; Byggnadsteknik;

   Abstract : 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. READ MORE

7. 5. 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
