  1. 1. The Effect of CO2-Pneumoperitoneum on Ventilation Perfusion Distribution of the Lung

    Sammanfattning : Laparoscopic operations are a common and popular way for abdominal procedures. They are usually performed by insufflation of carbon dioxide (CO2) into the abdominal cavity. However, insufflation of CO2 may interfere with cardiac and circulatory as well as respiratory functions. The CO2-pneumoperitoneum (PP) may cause hypercarbia and acidosis. LÄS MER

  3. 2. Ventilation/Perfusion Matching and its Effect on Volatile Pharmacokinetics

    Författare :Moritz Andreas Kretzschmar; Anders Larsson; Jan Jakobsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; Animal models in research; Mass spectrometry; Gas chromatography; MIGET; Ventilation-perfusion; Desflurane; Isoflurane; Bronchoconstriction; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : The mismatching of alveolar ventilation and perfusion (VA/Q) is the major determinant of impaired gas exchange. The gold standard for analyzing VA/Q distribution is the multiple inert gas elimination technique (MIGET), conventionally based on gas chromatography (GC), and, although simple in principle, a technically demanding procedure limiting its use.

  4. 3. Evaluation of efficacy and safety of pulsed inhaled nitric oxide in the anesthetized horse : preparing for clinical use

    Författare :Tamara Grubb; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Anesthetized, recumbent horses commonly develop hypoxemia secondary to ventilation/perfusion (VA/Q) mismatch and shunting of pulmonary blood (Qs/Qt) through atelectatic lung regions. Hypoxemia in the anesthetized horse is difficult to treat and ventilatory therapy is often ineffective. LÄS MER

  5. 4. Effect of body posture on regional ventilation and perfusion at normal and increased gravity

    Författare :Johan Petersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The prone position is increasingly used to improve arterial oxygenation in intensive care patients with severe acute respiratory failure. This beneficial response is well documented but our understanding of the responsible mechanisms remains incomplete, as does our knowledge of the effect of posture on lung function in healthy individuals.
