  1. 1. Monitoring with end-tidal oxygen

    Författare :Jan Bengtsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; paramagnetic; end-tidal oxygen; alveolar oxygen; oxygen consumption; alveolar ventilation; cardiac output; inotropic therapy; cardiac pacing; paediatric cardiac surgery;

  3. 2. A Surface Phase Model of the Alveolar Lining: Ultrastructural Analysis and in vivo Applications

    Författare :Marcus Larsson; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; X-ray diffraction; cryo-TEM; dynamic swelling; ARDS; surface phase; surfactant replacement therapy; cholesterol; minimal surface; pulmonary surfactant; alveolar surface; Physiology; Fysiologi;

    Sammanfattning : In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g. LÄS MER

  4. 3. Lung aeration and pulmonary gas exchange during general and epidural anaesthesia : Influenced by inspired oxygen concentration and diaphragm shape

    Författare :Adrian Reber; Uppsala universitet; []
    Nyckelord :Medical sciences; Anesthesia: epidural; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Induction of general anaesthesia causes a rapid decrease in functional residual capacity, which can promote alveolar collapse (atelectasis) and airway closure in dependent lung regions. Mismatching of ventilation and perfusion (VA/Q) in the lungs is accompanied by impairment of pulmonary gas exchange. LÄS MER

  5. 4. The dynostatic algorithm in adult and paediatric respiratory monitoring

    Författare :Sören Söndergaard; Göteborgs universitet; []
    Nyckelord :monitoring; respiratory mechanics; lung model; fibre optic pressure measurement; alveolar pressure; dynostatic algorithm;

    Sammanfattning : Introduction: Positive pressure ventilation carries a risk of aggravating systemic and lung disease. Monitoring of ventilatory pressure and volume is important to minimize this risk. Conventionally, the pressure of the respiratory system is measured outside the patient. LÄS MER

  7. 5. Non-invasive optical monitoring of free and bound oxygen in humans

    Författare :Emilie Krite Svanberg; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensive care; oxygenation; free gas; near-infrared spectroscopy; absorption spectroscopy; scattering;

    Sammanfattning : Background: Possibilities of detecting oxygen - both in its free form, as gas in the lungs, and in its bound form, as oxygenated hemoglobin - have been explored in this thesis. Perfusion and oxygenation of vital organs (e.g. LÄS MER
