  1. 1. Extreme hemodilution: Effects of inhalation anesthetics, hypoxia, and blood loss. An Experimental study in pigs

    Författare :Henning Schou; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; oxygen saturation.; blood volume; coronary circulation; blood lactate; oxygen uptake; Anemia; oxygen delivery; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : Hemodilution reduces the need for blood transfusion and hereby the risk for transmission of infectious agents. The present study investigated effects on systemic and myocardial circulation and oxygenation, and blood lactate concentrations; induced by nitrous oxide, isoflurane, hypoxia, and uncompensated blood loss, in pigs hemodiluted to a hematocrit of 11%.

  3. 2. Multispectral imaging of hemoglobin oxygen saturation in skin microcirculation

    Författare :Maria Ewerlöf; Göran Salerud; Tomas Strömberg; Marcus Larsson; Maurice C. G. Aalders; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multispectral imaging; hemoglobin oxygen saturation; microcirculation;

    Sammanfattning : The ability to measure microcirculatory parameters such as hemoglobin oxygen saturation is important since it mirrors the microcirculatory state of the body. The microcirculation delivers oxygen and nutrients to the cells of the body and, if impaired, may be a sign of circulatory failure. LÄS MER

  4. 3. Preclinical Studies for Cryoprevention of Oral Mucositis

    Författare :Java Walladbegi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Animal model; Chemotherapy; Cryotherapy; Hematopoietic stem cell transplantation; Ice chips; Intraoral cooling device; Microcirculation; Randomized controlled trial; Tissue-engineered oral mucosa; Tissue oxygen saturation; Tolerability;

    Sammanfattning : Oral mucositis (OM) is a debilitating adverse effect, with a prevalence of up to 80% in patients with cancer who are conditioned with high-dose chemotherapy prior to hematopoietic stem cell transplantation. In its mildest form, OM is characterized by erythema. However, as it worsens, it can give rise to painful ulcerations in the oral mucosa. LÄS MER

  5. 4. Model-based quantitative assessment of skin microcirculatory blood flow and oxygen saturation

    Författare :Hanna Jonasson; Tomas Strömberg; Bruce Tromberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The microcirculation, involving the smallest vessels in the body, is where the oxygen transport to all tissue occurs. Evaluating microcirculatory parameters is, therefore, important and involves the quantification of oxygen content of red blood cells (RBCs), the amount of RBCs and their speed. LÄS MER

  7. 5. Photon propagation in tissue and in biological fluids : applied for vascular imaging and haemodialysis monitoring

    Författare :Ivo Fridolin; David T. Delpy; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis focuses on the photon propagation in tissue and in biological fluids in two main areas: (1) optical vessel imaging and (2) monitoring solutes removed in haemodialysis.The aim of the optical vessel imaging study was to design and assess a new optical scanning technique for vessel imaging using NIR radiation.
