2. 16. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

   Author : Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Abstract : 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. READ MORE

4. 17. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury

   Author : Mariangela Pellegrini; Anders Sune Larsson; Göran Hedenstierna; Michael Quintel; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute respiratory distress syndrome; artificial respiration; diaphragm; pulmonary atelectasis; lung imaging; respiratory system; animal model; Fysiologi; Physiology; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Abstract : 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. READ MORE

5. 18. Artificial Neural Networks (ANN) in the Assessment of Respiratory Mechanics

   Author : Gaetano Perchiazzi; Göran Hedenstierna; Björn Jonson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; artificial neural networks; respiratory system compliance; respiratory system resistance; respiratory system time constant; intrinsic positive end expiratory pressure; PEEPi; animal model; acute lung injury; oleic acid; Otis model; Fysiologi; Physiology; Fysiologi;

   Abstract : 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. READ MORE

6. 19. Aspects on ventilation induced stress and strain on regional and global inflammation in experimental acute respiratory distress syndrome

   Author : Jaime Retamal Montes; Anders Larsson; Göran Hedenstierna; Alejandro Bruhn; Björn Jonson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ARDS; VILI; respiratory rate; strain; PET;

   Abstract : 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)”. READ MORE

7. 20. Vascular effects of hyperoxaemia and its mechanisms in man

   Author : Andreas Rousseau; Göran Hedenstierna; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Most cells in the human body cannot survive without oxygen. The regulation of oxygen delivery to meet demands of tissues remains contentious. READ MORE
