  1. 1. Photoplethysmography : methodological studies and applications

    Författare :Lars-Göran Lindberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : 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. LÄS MER

  3. 2. Aspects of Static Multi-Class Traffic equilibria under Congestion Pricing

    Författare :Per Olov Lindberg; Lars-Göran Mattsson; David Watling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic; congestion pricing; equilibria; marginal social cost; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Congestion charging is a now accepted means of influencing traffic to behave in a more socio-economic optimal way, like e.g. in the Stockholm project. Already early work, in the 1920’s, showed that road use can be inefficient due externalities, i. LÄS MER

  5. 4. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Författare :Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer; photoplethysmography; laser Doppler flowmetry; non-invasive; tissue blood flow; reactive hyperemia; pressure-induced vasodilation; interface pressure; risk assessment;

    Sammanfattning : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.
