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

    Author : Henning Schou; Anestesiologi och intensivvård; []
    Keywords : 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;

    Abstract : 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%.

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

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

    Abstract : 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. READ MORE

  5. 3. Hypoxic Blackout in Serial Freediving – Protective Mechanisms and Risk Factors

    Author : Frank Pernett; Erika Schagatay; Glenn Björklund; Anton Westman; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breath-hold diving; diving response; hyperventilation; hypoxia; oxygen saturation; oxygen stores; pulse oximetry; sonography; splenic contraction.;

    Abstract : Breath-hold diving or freediving exposes the body to stressors such as low oxygen and high carbon dioxide levels in the blood, increased hydrostatic pressure, and cold. The reduction in blood oxygen levels is considered a primary factor for loss of consciousness while diving. This is known as hypoxic blackout. READ MORE

  7. 5. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II

    Author : Sindra Peterson Årsköld; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; S2 state; second cycle; Biochemistry; Metabolism; Biokemi; metabolism; S0 state; light-adaptation; pulsed EPR; methanol; relaxation; microwave power saturation; S-cycle; Oxygen-evolving complex; Water-oxidizing complex;

    Abstract : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). READ MORE
