  1. 6. Tomographic ventilation-perfusion lung scintigraphy in cardiopulmonary disease

    Författare :Jonas Jögi; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Technegas; Ventilation-Perfusion Single Photon Emission Computed Tomography; Chronic obstructive pulmonary disease; Heart failure; Pulmonary embolism;

    Sammanfattning : Respiration relies, among other things, on the balance between regional ventilation and perfusion in the lungs. There are many cardiopulmonary diseases, such as pulmonary embolism (PE), chronic obstructive pulmonary disease (COPD) and left heart failure (LHF), which can affect respiration negatively. LÄS MER

  4. 8. 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.

  5. 9. Pulmonary atresia with intact ventricular septum epidemiology and outcome in children born in Sweden 1980-1999

    Författare :Britt-Marie Ekman-Joelsson; Göteborgs universitet; []
    Nyckelord :pulmonary atresia with intact ventricular septum; ventriculo coronary arterial communications; biventricular repair; univentricular palliation; myocardial perfusion; myocardial function; cardiopulmonary exercise; lung function; quality of life; mortality; outcome;

    Sammanfattning : Aims: To describe children born with pulmonary atresia with intact ventricular septum (PA-IVS) in Sweden between 1980 and 1999, the incidence and outcome of PA-IVS, to examine cardio-pulmonary outcomes in survivors and to evaluate their quality of life. Material and methods: Eighty-four subjects were identified. LÄS MER

  7. 10. Regional ventilation, pulmonary perfusion and gas exchange in supine and prone positions

    Författare :Margareta Mure; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ARDS; ALI; CPAP; Gas exchange; Prone position; Regional ventilation; Regional perfusion; Supine position;

    Sammanfattning : The rationale for treating patients with acute lung injury in the prone position springs from a number of observations. Clinical reports have documented improved oxygenation when patients are turned prone. Regional vascular conductance is higher in dorsal lung regions regardless of posture. LÄS MER
