  1. 1. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling

    Författare :Ramin Ghorbani; Florian M. Schmidt; Anders Blomberg; Christoffer Boman; Staffan Schedin; Jonathan Beauchamp; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon monoxide CO ; pulmonary gas exchange; computational modeling; real-time breath gas analysis; single-exhalation profile; laser absorption spectroscopy; nonlinear least-squares fitting; breath sampling; baseline level; diurnal variation; healthy population; exposure study; fysik; Physics; Physiology; fysiologi;

    Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

  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. Atelectasis and gas exchange impairment after cardiopulmonary bypass : An experimental study

    Författare :Lennart Magnusson; Uppsala universitet; []
    Nyckelord :Medical sciences; Lung: cardiopulmonary bypass; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Despite of the improvement in management and equipment for cardiopulmonary bypass (CPB), postoperative pulmonary complications remain a major problem after cardiac surgery. In the present thesis, using a pig model, atelectasis has been tested as a cause of the increase in intrapulmonary shunt commonly seen after CPB. LÄS MER

  7. 5. Surgically corrected univentricular hearts. Anatomical, haemodynamic and functional status at a long-term follow-up

    Författare :Eva Strömvall-Larsson; Göteborgs universitet; []
    Nyckelord :cavopulmonary connections; univentricular hearts; long-term follow-up; pulmonary; arteriovenous malformations; lung volumes; cardiac output; pulmonary gas exchange and maximal; exercise studies;

    Sammanfattning : The Fontan operation and its modifications are applied to a large spectrum of congenital heart defectswith univentricular physiology. The Fontan circulation is characterised by a reduced, non-pulsatilepulmonary blood flow and the elevated central venous pressure is the main driving force for thepulmonary blood flow. LÄS MER
