1. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin
Abstract : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.

2. Non-invasive optical monitoring of free and bound oxygen in humans
Abstract : Background: Possibilities of detecting oxygen - both in its free form, as gas in the lungs, and in its bound form, as oxygenated hemoglobin - have been explored in this thesis. Perfusion and oxygenation of vital organs (e.g. READ MORE

3. Regional ventilation, pulmonary perfusion and gas exchange in supine and prone positions
Abstract : The rationale for treating patients with acute lung injury in the prone position springs from a number of observations. Clinical reports have documented improved oxygenation when patients are turned prone. Regional vascular conductance is higher in dorsal lung regions regardless of posture. READ MORE

4. Regional pulmonary vasoreactivity, with special reference to nitric oxide, prostacyclin and body posture
Abstract : The primary aim of the study was to investigate possible mechanisms behind the improved arterial oxygenation in ventilator-treated patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) when turned into prone position. A secondary aim was to discover new knowledge of possible importance for treatment of patients with oxygenation problems in intensive care and during anesthesia. READ MORE

5. Effect of body posture on regional ventilation and perfusion at normal and increased gravity
Abstract : The prone position is increasingly used to improve arterial oxygenation in intensive care patients with severe acute respiratory failure. This beneficial response is well documented but our understanding of the responsible mechanisms remains incomplete, as does our knowledge of the effect of posture on lung function in healthy individuals.
