  1. 1. FRC in acute lung injury. Experimental and clinical studies

    Författare :Christian Rylander; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Recruitment of small size lungs - experimental studies

    Författare :Angela Hanson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lung recruitment; PEEP titration; VTCO2; Cdyn; computed tomography; cardiac output; atelectasis; lung aeration; driving pressure;

    Sammanfattning : Background: Patients - both children and adults - undergoing anesthesia and mechanical ventilation rapidly develop atelectasis. Even more severe problems occur in patients with acute lung injury/acute respiratory distress syndrome. LÄS MER

  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. 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

  7. 5. Lung aeration and pulmonary gas exchange during general and epidural anaesthesia : Influenced by inspired oxygen concentration and diaphragm shape

    Författare :Adrian Reber; Uppsala universitet; []
    Nyckelord :Medical sciences; Anesthesia: epidural; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Induction of general anaesthesia causes a rapid decrease in functional residual capacity, which can promote alveolar collapse (atelectasis) and airway closure in dependent lung regions. Mismatching of ventilation and perfusion (VA/Q) in the lungs is accompanied by impairment of pulmonary gas exchange. LÄS MER
