  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; 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. 3. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans

    Författare :Daniele A. Cardinale; Filip J Larsen; David Bishop; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondria; OXPHOS; p50mito; mitochondrial oxygen affinity; oxygen extraction; sex difference; hyperoxia; training; muscle metabolism; performance; HIIT; Medicin Teknik; Medicine Technology;

    Sammanfattning : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.

  4. 4. Exercise physiology and cardiac function. Aspects on determinants of maximal oxygen uptake

    Författare :Katarina Steding Ehrenborg; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; respiratory indices; peak oxygen uptake; heart failure; cardiac magnetic resonance imaging; exercise physiology;

    Sammanfattning : Although the athlete's heart has been of interest for over 100 years, further characterization of the athletes heart is needed in order to understand how training affects cardiac dimensions and function. Few studies have investigated the effects of training in female athletes and few have compared males and females. LÄS MER

  5. 5. Assessment of Aerobic Capacity A Novel Rating Scale and Further Development of an Exercise Test including Analysis of Gas Exchange

    Författare :Anita Wisén; Fysioterapi; []
