  2. 16. Non-invasive optical monitoring of free and bound oxygen in humans

    Author : Emilie Krite Svanberg; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensive care; oxygenation; free gas; near-infrared spectroscopy; absorption spectroscopy; scattering;

    Abstract : Background: Possibilities of detecting oxygen - both in its free form, as gas in the lungs, and in its bound form, as oxygenated hemoglobin - have been explored in this thesis. Perfusion and oxygenation of vital organs (e.g. READ MORE

  4. 17. Photoplethysmography : methodological studies and applications

    Author : Lars-Göran Lindberg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Photoplethysmography (PPG), an optical non-invasive technique for measuring skin perfusion changes, was investigated and evaluated. The method was compared with laser Doppler flowmetry (LDF) when measuring perfusion changes in human fingers and forearms. READ MORE

  5. 18. Optical measurements in brain tissue during radio frequency lesioning

    Author : Johan Antonsson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Radio frequency (RF) lesioning is a well well-known procedure within the field of stereotactic neurosurgery, commonly used for the treatment of movement disorders. During the intervention, an RF-electrode is inserted into the deeper parts of the brain, where a small volume of malfunctioning brain tissue will be coagulated. READ MORE

  6. 19. Factors influencing splanchnic microcirculation in animal models of endotoxaemia

    Author : Andreas Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microcirculation;

    Abstract : Even though severe sepsis and septic shock therapy has improved in recent years, mortality remains high (22-50%). Disturbances in splanchnic organ homeostasis and increases in gut permeability have long been presumed to contribute to systemic inflammation and multiple organ dysfunction syndrome in critical illness and septic shock.

  7. 20. Studies on Polarised Light Spectroscopy

    Author : Max Bergkvist; Simon Farnebo; Erik Tesselaar; Folke Sjöberg; Johan Thorfinn; Knut Kvernebo; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. READ MORE
