1. Respiratory inductive plethysmography (RIP) : calibration, breathing pattern analysis and external CO2 dead space measurement
Sammanfattning : 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. LÄS MER
2. Titrating Open Lung PEEP in Acute Lung Injury : A clinical method based on changes in dynamic compliance
Sammanfattning : 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. LÄS MER
3. Det permanentade provisoriet : ett återanvänt industriområde i väntan på rivning eller erkännande
Sammanfattning : In this thesis, the story is told about the 'permanent-provisional state' that has come about in a never completed, and now degenerated, industrial zone in Göteborg. In the "Gustaf Dalén area" there is a rich mixture of activities, and by and large no resident population. LÄS MER
4. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space
Sammanfattning : 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. LÄS MER
5. Ergonomics of Breathing Apparatus, with Special Reference to Work of Breathing, Dead Space and Breathing Resistance
Sammanfattning : 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. LÄS MER
