  1. 1. Studies on nitric oxide in the respiratory system

    University dissertation from Stockholm : Karolinska Institutet, false

    Author : Ulla Schedin; Karolinska Institutet.; Karolinska Institutet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitric oxide; endogenous; respiratory system; neonate; prematureinfant; animal; primate; elephant; chemiluminescence; electrochemical; nitrogen dioxide; trachea; nose; ;

    Abstract : STUDIES ON NITRIC OXIDE IN THE RESPIRATORY SYSTEM Ulla Schedin, MD, Dissertation from the Division of Anaesthesiaand Intensive Care, Karolinska Institute Danderyd Hospital, S-182 88, Danderyd, Sweden Nitric oxide (NO) is formed in biological tissues and has regulatory functionsin many organ systems. Endogenous NO has been found in exhaled air and NO is consideredto have effects on the pulmonary circulation and bronchial tone, and to be one ofthe mediators for the circulatory adaptation at birth.

  2. 2. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

    University dissertation from Stockholm : Karolinska Institutet, false

    Author : Edoardo De Robertis; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

    Abstract : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. READ MORE

  3. 3. Endothelin receptor changes during inflammation in the lung

    University dissertation from Laboratory of Experimental Vascular Research Department of Clinical Sciences Lund University

    Author : Bengt Granström; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Andningsorganen; Respiratory system; Upregulation; Smooth muscle cells; Smoking; Sephadex; Remodeling; Rat; mRNA; Human; ETB receptor; ETA receptor; Lung; Endothelin; Asthma bronchiale; Contraction;

    Abstract : Endothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases.

  4. 4. Mucins in normal and diseased airways

    University dissertation from Laboratory of Experimental Vascular Research Department of Clinical Sciences Lund University

    Author : Hans Hovenberg; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; Submucosal glands; Goblet cells; Organ culture; Respiratory tract; Mucins; Mucus glycoproteins; Andningsorganen;

    Abstract : Mucus glycoproteins (mucins) are the principal constituents of respiratory secretions in health and disease. The increased 'acidity' of mucin producing cells in the bronchitic airways is not reflected in a change of negative charge of bronchitic mucins. READ MORE

  5. 5. Jet Ventilation for Airway Surgery The Influence of Mode and Frequency on Ventilation Efficacy

    University dissertation from Laboratory of Experimental Vascular Research Department of Clinical Sciences Lund University

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

    Abstract : 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.
