  1. 1. On cardiovascular responses to hypovolemic circulatory stress. An experimental study in man

    Författare :Henrik Olsen; Helsingborg Kliniska Vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; secreting systems; Endocrinology; vein.; type 1 diabetes; skeletal muscle; LBNP; compliance; CFC; Ageing; baroreceptor; Endokrinologi; sekretion; diabetologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Aged subjects have a decreased tolerance to hypovolemia, which could contribute to their increased cardiovascular morbidity. One possible etiological factor might be an age-related reduction in the efficiency of the baroreceptor reflex axis. LÄS MER

  3. 2. Cardiovascular responses to hypovolemic circulatory stress in women : With special reference to venous compliance and capacitance

    Författare :Marcus Lindenberger; Toste Länne; Peter Friberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiology; Kardiologi;

    Sammanfattning : Acute haemorrhage is a leading cause of death in trauma. Young women (YW) seem more susceptible to hypovolemic circulatory stress than young men (YM), but the underlying mechanisms are not clear. LÄS MER

  4. 3. Cardiovascular regulation in women with vasovagal syncope : With special reference to the venous system

    Författare :Johan Skoog; Toste Länne; Marcus Lindenberger; Helene Zachrisson; Ola Eiken; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. LÄS MER

  5. 4. Nitric oxide production by the intestinal mucosa during hypoperfusion

    Författare :Johan Snygg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; nitric oxide synthase; intestinal epithelium; hemorrhagic shock; cardiac tamponade; septic shock; lower body negative pressure; splanchnic circulation; substrate; laser Doppler;

    Sammanfattning : The present thesis is based on the concept that gastrointestinal blood hypoperfusion is a common phenomenon associated with critical illness. Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.
