  2. 1. 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

  4. 2. Transpulmonary pressure during mechanical ventilation

    Author : Christina Grivans; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Acute lung injury; Acute respiratory distress syndrome; Lung volume measurements; Electric Impedance diagnostic use; Lung elastance; Transpulmonary pressure; Esophageal pressure;

    Abstract : Background: Mechanical ventilation can aggravate lung injury by repetitive opening and closing of lung units, overdistention and undue pressure on pulmonary structures. Guidelines exist for lung protective ventilation, but individualized ventilator settings, based on partitioning of respiratory mechanics in pulmonary and chest wall complex components, would be beneficial.

  5. 3. Ergonomics of Breathing Apparatus, with Special Reference to Work of Breathing, Dead Space and Breathing Resistance

    Author : Dan E. Warkander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance; control of breathing; static lung loading; work of breathing; breathing resistance; elastance; helium; hydrogen; hypercapnia; diving; CO2;

    Abstract : A breathing apparatus is a very useful device. It allows people to breathe relatively freely while entering environments that otherwise would be impenetrable such as extreme altitudes, smoke filled buildings, ocean depths and the surface of the moon. However, a breathing apparatus does have some disadvantages. READ MORE

  6. 4. Lung and chest wall properties during mechanical ventilation

    Author : Per Erik Persson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Respiratory mechanics; Esophageal pressure; Positive end-expiratory pressure;

    Abstract : Background: Mechanical ventilation causes injury to the lungs due to high pressures and high volumes. Pressure affecting the lungs, the transpulmonary pressure, needs to be monitored to minimise harmful side effects but then lung and chest wall mechanics need to be separately considered. READ MORE

  7. 5. Airway hyperresponsiveness and viral recognizing toll-like receptors

    Author : Magnus Starkhammar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Common colds caused by viruses are, in healthy individuals, usually self-limited and with relatively mild symptoms. In asthmatic individuals, respiratory viruses can burst the defense immune system and trigger asthma exacerbations, including causing airway hyperresponsiveness (AHR). READ MORE
