    Sammanfattning : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. LÄS MER

  3. 2. Jet Ventilation for Airway Surgery : The Influence of Mode and Frequency on Ventilation Efficacy

    Författare :Robert Sütterlin; Peter Frykholm; Anders Larsson; Ullman Johan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; jet ventilation; airway obstruction; tracheal stenosis; HFJV; SHFJV; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : In surgery for airway obstruction, the anesthetist and the ear-nose-throat surgeon share the approach to the airway and jet ventilation (JV) is a mutually convenient ventilation technique for both parties. As a consequence of the open system jet ventilation is applied in, bedside measurements of lung volumes are cumbersome to perform and thus, there is a lack of studies comparing different modes of JV or investigating the influence of ventilator settings on lung volumes and gas exchange.

  4. 3. Interleukin-17 in non-allergic airway inflammation

    Författare :Martti Laan; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IL-17; airway inflammation; bronchial epithelial cells; neutrophils; T-lymphocytes; IL-8; IL-6; MAP kinases.;

    Sammanfattning : Chronic bronchitis, chronic obstructive pulmonary disease (COPD), bronchial asthma and cystic fibrosis are common clinical disorders all characterized by airway neutrophilia. By releasing proteolytic enzymes and free oxygen radicals, neutrophils can contribute to the main features of these diseases such as airway obstruction, hypersecretion and remodelling. LÄS MER

  5. 4. Assessment of increased upper airway resistance in snorers. Methodological and diagnostic considerations

    Författare :Sören Berg; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arousals.; pharyngeal pressure; intrathoracic pressure; hypopnea; respiratory ventilation; oxygenation; Non apneic snorers; upper airway obstruction; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : Sleep-related partial upper airway obstruction may cause increased morbidity and mortality, but diagnosis and treatment of patients is varying and inconsistent. The present studies were aimed to evaluate presently applied indirect methods for assessing respiratory ventilation and to investigate the value and accuracy in estimating upper airway resistance during sleep by measuring intrathoracic pressure variation with a microchip catheter in the esophagus.
