1. Real-time multi-exposure laser speckle contrast imaging of skin microcirculatory perfusion
Sammanfattning : The microcirculation, the blood flow in the smallest blood vessels in the body, has a vital function as this is where oxygen and nutrients diffuses from the blood to to the surrounding cells. An important quantity is the tissue perfusion, a measure of the microcirculation’s capacity to provide oxygen and nutrients to the cells. LÄS MER
2. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function
Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER
3. Model-based quantitative assessment of skin microcirculatory blood flow and oxygen saturation
Sammanfattning : The microcirculation, involving the smallest vessels in the body, is where the oxygen transport to all tissue occurs. Evaluating microcirculatory parameters is, therefore, important and involves the quantification of oxygen content of red blood cells (RBCs), the amount of RBCs and their speed. LÄS MER
4. Factors influencing splanchnic microcirculation in animal models of endotoxaemia
Sammanfattning : Even though severe sepsis and septic shock therapy has improved in recent years, mortality remains high (22-50%). Disturbances in splanchnic organ homeostasis and increases in gut permeability have long been presumed to contribute to systemic inflammation and multiple organ dysfunction syndrome in critical illness and septic shock.

5. Endothelin receptor antagonism and hypertonic solutions in experimental endotoxin shock
Sammanfattning : Sepsis is a common and serious condition among patients in the intensive care unit. It is characterized by a systemic inflammatory response, resulting in cardiovascular instability and impaired organ tissue oxygenation due to hypoperfusion and inflammatory changes. LÄS MER
