  2. 1. Pathophysiological and Histomorphological Effects of One-Lung Ventilation in the Porcine Lung

    Author : Alf Kozian; Göran Hedenstierna; Thomas Hachenberg; Filip Freden; Sten Walther; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alveolar Recruitment Manoeuvre; One-Lung Ventilation; Lung Protective Ventilation; Tidal Volume; Computed Tomography; Tidal Recruitment; Animal Model; Open Thoracic Surgery; Ventilation Perfusion Distribution; Single Photon Emission Computed Tomography; Diffuse Alveolar Damage; Medical laboratory science; Medicinsk laboratorievetenskap; Anestesiologi; Anaesthesiology;

    Abstract : Thoracic surgical procedures require partial or complete airway separation and the opportunity to exclude one lung from ventilation (one-lung ventilation, OLV). OLV is commonly associated with profound pathophysiological changes that may affect the postoperative outcome. READ MORE

  4. 2. Minimal volume ventilation in lung injury : With special reference to apnea and buffer treatment

    Author : Staffan Höstman; Anders Larsson; Hans Hjelmqvist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VILI; THAM; buffers; apneic oxygenation; respiratory acidosis; hypercapnia; low volume ventilation; mechanical ventilation; ultra-protective ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. READ MORE

  5. 3. Influence of tidal volume on pulmonary gas exchange during general anaesthesia

    Author : Bruno Enekvist; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; sevoflurane; cardiac output; functional residual capacity; pulmonary gas exchange;

    Abstract : Background and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP.

  6. 4. Monitoring alveolar recruitment in the critically ill - Patient studies using electric impedance tomography and volume-dependent compliance

    Author : Karin Lowhagen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALI; ARDS; compliance; end-expiratory lung volume; EELV; EIT; electric impedance tomography; lung recruitment; morbid obesity; PEEP; recruitment manoeuvre; regional ventilation; volume-dependent compliance;

    Abstract : Background: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are associated with a high mortality rate and poor long term outcome in terms of quality of life, for those who survive. Similarly, patients with morbid obesity are at risk for respiratory complications when subjected to anaesthesia and surgery. READ MORE

  7. 5. FRC in acute lung injury. Experimental and clinical studies

    Author : Christian Rylander; Göteborgs universitet; []
    Keywords : Airway obstruction; Acute lung injury; Acute respiratory distress syndrome; Attenuation; Computed tomography; End-expiratory lung volume; Functional residual capacity; Gas dilution; Hounsfield unit; Lung volume; Oleic acid; Recruitment; Time constant;

    Abstract : Respiratory failure due to acute lung injury (ALI) of diffuse inflammatory origin is a major cause of respiratory failure treated in intensive care units. In ALI, FRC is reduced by various mechanisms associated with hypoxemia and consolidation of the lung. READ MORE
