  2. 11. Open and closed endotracheal suctioning. Experimental and human studies

    Author : Sophie Lindgren; Göteborgs universitet; []
    Keywords : suctioning; endotracheal; closed system suctioning; monitoring; lung volume; airway pressure; lung recruitment; bronchoalveolar lavage; acute lung injury;

    Abstract : Background: The practice of endotracheal suctioning of ventilator treated patients is necessary to remove secretions to prevent obstruction of the endotracheal-tracheal tube and lower airways. This very common procedure creates a large variety of heart-lung interferences. READ MORE

  4. 12. Lung volumes and lung mechanics in anesthetized children

    Author : Adalbjörn Thorsteinsson; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sulfur hexafluoride; Anaesthesiology; lung volumes; lung compliance; Anesthesia: pediatric; functional residual capacity; intensive care; Anestesiologi; ventilation inhomogeneity; intensivvård; airway closure;

    Abstract : The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. READ MORE

  5. 13. Recruitment of small size lungs - experimental studies

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

    Abstract : 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. READ MORE

  6. 14. The effects of posture, airway pressure and anesthesia on regulation of the regional ventilation and perfusion distribution in healthy humans

    Author : Sven Nyrén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Anesthesia; ALI; ARDS; CPAP; Dual isotope; Mechanical ventilation; Nitric oxide; Nuclear medicine; Prone position; Regional ventilation; Regional perfusion; SPECT;

    Abstract : Gas exchange has been observed to vary with posture in adult respiratory distress syndrome (ARDS) patients. In this thesis, the effect of posture on theregional distribution of ventilation (V) and perfusion (Q) in the lungs under normal breathing with and without continuous positive airway pressure (CPAP) and during general anesthesia with mechanical ventilation was studied.

  7. 15. 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
