  2. 6. Theoretical modelling of tumour oxygenation and influences on treatment outcome

    Author : Iuliana Toma-Dasu; Mikael Karlsson; Svensson Hans; J F Fowler; Borivoj Vojnovic; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Computer simulation; Electrode; Polarographic measurements; Tumour oxygenation; Hypoxia; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

    Abstract : 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. READ MORE

  4. 7. Benefits of Spontaneous Breathing : Compared with Mechanical Ventilation

    Author : László Vimláti; Michael Lichtwarck-Aschoff; Anders Larsson; Lars Wiklund; Carl-Johan Wickerts; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spontaneous breathing; mechanical ventilation; pulmonary shunt; oxygenation; hypoxic pulmonary vasoconstriction; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : 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.

  5. 8. Non-invasive optical monitoring of free and bound oxygen in humans

    Author : Emilie Krite Svanberg; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensive care; oxygenation; free gas; near-infrared spectroscopy; absorption spectroscopy; scattering;

    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

  6. 9. Vacuum-Assisted Closure Therapy - A new Treatment Modality in Poststernotomy Mediastinitis

    Author : Ronny Gustafsson; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Infektioner; Infections; Mortality; Lactate; Wound Healing; Respiration; Oxygenation; Circulation; Vacuum-assisted Closure; Mediastinitis; traumatology; Cardiac Surgery; Kirurgi; ortopedi; traumatologi;

    Abstract : Poststernotomy mediastinitis is a devastating complication associated with median sternotomy, which occurs mainly after cardiac surgery. The optimal treatment is still controversial. READ MORE

  7. 10. Assessment of increased upper airway resistance in snorers. Methodological and diagnostic considerations

    Author : Sören Berg; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arousals.; pharyngeal pressure; intrathoracic pressure; hypopnea; respiratory ventilation; oxygenation; Non apneic snorers; upper airway obstruction; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : 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.
