  2. 1. Respiratory inductive plethysmography (RIP) : calibration, breathing pattern analysis and external CO2 dead space measurement

    Author : Tomas Strömberg; Gert Nilsson; Per M. Gustafsson; Steffen Groth; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Respiratory inductive plethysmography (RIP) is an important tool for ventilatory monitoring in research studies because it has minimal influence on the spontaneous breathing pattern and because the rib cage and abdominal contributions to the breaths are measured. RIP measures changes in rib cage and abdominal cross-sectional areas which are translated into lung volume estimates via RIP calibration against e. READ MORE

  4. 2. Titrating Open Lung PEEP in Acute Lung Injury : A clinical method based on changes in dynamic compliance

    Author : Fernando Suarez Sipmann; Göran Hedenstierna; Hans Hedenström; Stefan Lundin; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; PEEP; open lung; recruitment; dead space; electrical impedance tomography; ARDS.; Medicine; Medicin;

    Abstract : The recognition that supportive mechanical ventilation can also damage the lung, the so called ventilation induced lung injury (VILI), has revived the more than 40 year long debate on the optimal level of PEEP to be used. It is established that the prevention of VILI improves patient outcome and that PEEP exerts protective effects by preventing unstable diseased alveoli from collapsing. READ MORE

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

    Author : Edoardo De Robertis; Lund Klinisk fysiologi; []
    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

  6. 4. 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

  7. 5. Biodiversity and green infrastructure in urban landscapes

    Author : Ulf G. Sandström; Per Angelstam; Abdul Khakee; Kjell Nilsson; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi; Birds in cities; Communication between sciences; Conservation planning; Landscape ecology; Swedish green planning; Urban green space; Urban planning; Urban vegetation; Biologi med ekologisk inriktning; Biology; Biologi; Biologi med ekologisk inriktning;

    Abstract : In this thesis, I evaluate the extent to which biodiversity is affected, and taken into consideration by, urban planning. Based on landscape ecology, I apply an interdisciplinary approach. READ MORE
