16. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions
Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER
17. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury
Sammanfattning : Despite being an essential life-support strategy in severe respiratory failure, mechanical ventilation can, if not optimally set and monitored, lead to injury of the lung parenchyma and diaphragm. These conditions are called ventilator-induced lung injury and ventilator-induced diaphragmatic dysfunction (VIDD), respectively. LÄS MER
18. Artificial Neural Networks (ANN) in the Assessment of Respiratory Mechanics
Sammanfattning : The aim of this thesis was to test the capability of Artificial Neural Networks (ANN) to estimate respiratory mechanics during mechanical ventilation (MV). ANNs are universal function approximators and can extract information from complex signals. LÄS MER
19. Aspects on ventilation induced stress and strain on regional and global inflammation in experimental acute respiratory distress syndrome
Sammanfattning : Mechanical ventilation (MV) is a life-saving therapy in acute respiratory distress syndrome (ARDS), a condition that affects 3000 patients/year in Sweden with a mortality rate of about 40%. However, MV may induce or worsen lung injury causing “ventilator-induced lung injury (VILI)”. LÄS MER
20. Vascular effects of hyperoxaemia and its mechanisms in man
Sammanfattning : Most cells in the human body cannot survive without oxygen. The regulation of oxygen delivery to meet demands of tissues remains contentious. LÄS MER
