1. 16. ASPECTS OF FLUID THERAPY: An experimental study of the effects of systemic inflammation, microvascular permeability, blood pressure and plasma volume

   Författare :Maris Dubniks; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; activated protein C; SIRS; albumin; blood pressure; colloids; plasma volume; hypervolaemia; hypovolaemia; microcirculation; noradrenalin; permeability; prostacyclin;

   Sammanfattning : Adequate circulating blood volume is a prerequisite for circulatory stability. Fluid therapy aims at correcting hypovolaemia, and is an important part of the haemodynamic management of perioperative and critically ill patients. LÄS MER

3. 17. Aspects of lung mechanics during mechanical ventilation

   Författare :Magni Gudmundsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute respiratory failure; Acute respiratory distress syndrome; Mechanical ventilation; Transpulmonary pressure; Expiratory time constant; Esophageal pressure;

   Sammanfattning : Background: One of the most common diagnoses in the intensive care unit is acute respiratory failure. In its most severe form it is called acute respiratory distress syndrome and often requires mechanical ventilation. LÄS MER

4. 18. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

   Författare :Edoardo De Robertis; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

   Sammanfattning : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. LÄS MER

5. 19. Studies on Diesel sprays under non-reacting and reacting conditions

   Författare :Chengjun Du; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion flame; OH radical; ethanol; spray vaporization; soot formation; cavitation; turbulent; OH* chemiluminescence; laser extinction; LAS; Diesel sprays;

   Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER

7. 20. Coarctation of the aorta : register and imaging studies

   Författare :Daniel Rinnström; Bengt Johansson; Michael Henein; Martin Ugander; Gerhard-Paul Diller; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coarctation of the aorta; adult congenital heart disease; hypertension; left ventricular hypertrophy; body mass index; height; weight; register; CMR;

   Sammanfattning : Background Coarctation of the aorta (CoA) constitutes 5-8 % of all congenital heart disease (CHD) and is associated with long-term complications such as hypertension (HTN) and left ventricular hypertrophy (LVH). Factors associated with HTN, LVH, and diffuse myocardial fibrosis, are not yet fully explored in this population. LÄS MER
