1. 1. Pathophysiological and Histomorphological Effects of One-Lung Ventilation in the Porcine Lung

   Författare :Alf Kozian; Göran Hedenstierna; Thomas Hachenberg; Filip Freden; Sten Walther; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alveolar Recruitment Manoeuvre; One-Lung Ventilation; Lung Protective Ventilation; Tidal Volume; Computed Tomography; Tidal Recruitment; Animal Model; Open Thoracic Surgery; Ventilation Perfusion Distribution; Single Photon Emission Computed Tomography; Diffuse Alveolar Damage; Medical laboratory science; Medicinsk laboratorievetenskap; Anestesiologi; Anaesthesiology;

   Sammanfattning : Thoracic surgical procedures require partial or complete airway separation and the opportunity to exclude one lung from ventilation (one-lung ventilation, OLV). OLV is commonly associated with profound pathophysiological changes that may affect the postoperative outcome. LÄS MER

3. 2. The Immune Response to One-Lung Ventilation : Clinical and Experimental Studies

   Författare :Thomas Schilling; Göran Hedenstierna; Hans Hedenström; Thomas Hachenberg; Sven-Erik Ricksten; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; One-lung ventilation; open thoracic surgery; ventilation-induced lung injury; alveolar immune response; bronchoalveolar lavage; propofol; desflurane; cytokines; animal model; mRNA; RT-PCR; Medical laboratory science; Medicinsk laboratorievetenskap; anestesiologi; Anaesthesiology;

   Sammanfattning : One-lung ventilation (OLV) as an established procedure during thoracic surgery may be injurious in terms of increased mechanical stress characterised by alveolar cell stretch and overdistension, increased cyclic tidal recruitment of alveolar units, compression of alveolar vessels and increased pulmonary vascular resistance. This may result in ventilation-induced lung injury with pro-inflammatory cytokine production, leukocyte recruitment and neutrophil-dependent tissue destruction. LÄS MER

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

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

   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. 4. Laboratory Ventilation Systems: An Analysis of the Function and Flow Stability of Different Ductwork Design Alternatives

   Författare :Madis Laaniste; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory ventilation; transient flow simulation; fume hood;

   Sammanfattning : One of the prerequisites for high safety in laboratories for chemical and microbiological research is a well-functioning ventilation system. The most typical safety measure in these laboratories is to use a fume hood as a place for activities that can cause dangerous emissions to the room air. LÄS MER
