  1. 1. 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. Lung function after cardiac surgery : With special reference to atelectasis and ventilation-perfusion relationships

    Författare :Arne Tenling; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac surgery; thoracic epidural analgesia; vital capacity manoeuvre; computed tomography; ventilation-perfusion relationships; gas exchange; atelectasis; respiratory inductive plethysmography; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

    Sammanfattning : Patients undergoing cardiac surgery were investigated before and after the operation.Ventilation-perfusion (VA/Q) relationships were examined by the multiple inert gas elimination method, and atelectasis and aeration of the lungs were examined by computedtomography (CT).

  5. 4. 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

  7. 5. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea

    Författare :Jonas Appelberg; Göran Hedenstierna; Christer Janson; Karl Franklin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Sleep; Ventilation; Sleep apnea syndromes; Snoring; Lung volume; Respiration; Computed tomography; Ventilatory response; Ventilation-perfusion; Airway closure; Fysiologi; Physiology; Fysiologi; klinisk fysiologi; Clinical Physiology;

    Sammanfattning : Obstructive sleep apnea (OSA) appears to affect up to 5% of the population. The extent to what pulmonary function awake and during sleep relates to obstructive breathing and hypoxemia during sleep in these patients is unclear. LÄS MER
