6. Theoretical modelling of tumour oxygenation and influences on treatment outcome
Sammanfattning : One of the main problems in curing cancer resides in the different microenvironment existing in tumours compared to the normal tissues. The mechanisms of failure are different for radiotherapy and chemotherapy, but they all relate to the poor blood supply known to exist in tumours. LÄS MER
7. Benefits of Spontaneous Breathing : Compared with Mechanical Ventilation
Sammanfattning : When spontaneous breathing (SB) is allowed during mechanical ventilation (MV), atelectatic lung areas are recruited and oxygenation improves thereby. Whether unsupported SB at its natural pattern (without PEEP and at low pressure/small tidal volume) equally recruits and improves oxygenation, and if so by which mechanism, has not been studied.

8. Non-invasive optical monitoring of free and bound oxygen in humans
Sammanfattning : 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. LÄS MER
9. Vacuum-Assisted Closure Therapy - A new Treatment Modality in Poststernotomy Mediastinitis
Sammanfattning : Poststernotomy mediastinitis is a devastating complication associated with median sternotomy, which occurs mainly after cardiac surgery. The optimal treatment is still controversial. LÄS MER
10. Assessment of increased upper airway resistance in snorers. Methodological and diagnostic considerations
Sammanfattning : Sleep-related partial upper airway obstruction may cause increased morbidity and mortality, but diagnosis and treatment of patients is varying and inconsistent. The present studies were aimed to evaluate presently applied indirect methods for assessing respiratory ventilation and to investigate the value and accuracy in estimating upper airway resistance during sleep by measuring intrathoracic pressure variation with a microchip catheter in the esophagus.
