  1. 1. 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

  2. 2. Pulmonary Atelectasis in General Anaesthesia : Clinical Studies on the Counteracting Effects of Positive End-Expiratory Pressure

    Author : Erland Östberg; Mats Enlund; Lennart Edmark; Sophie Lindgren; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General anaesthesia; pulmonary atelectasis; positive end-expiratory pressure; oxygen; computed tomography; continuous positive airway pressure; mechanical ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Partial lung collapse, i.e., pulmonary atelectasis, is common during general anaesthesia. The main causal mechanism is reduced lung volume with airway closure and subsequent gas absorption from preoxygenated alveoli. READ MORE

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

    Author : Thomas Schilling; Göran Hedenstierna; Hans Hedenström; Thomas Hachenberg; Sven-Erik Ricksten; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Atelectasis during general intravenous anaesthesia with mechanical ventilation : mechanisms, prevention and treatment

    Author : Hans Ulrich Rothen; Uppsala universitet; []
    Keywords : MEDICINE; MEDICIN;

  5. 5. New methods for optimization of mechanical ventilation

    Author : Peter Kostic; Peter Frykholm; Anders Larsson; Johan Petersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mechanical ventilation; optoelectronic plethysmography; forced oscillation technique; laser interferometry; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Mechanical ventilation saves lives, but it is an intervention fraught with the potential for serious complications. Prevention of these complications has become the focus of research and critical care in the last twenty years. READ MORE
