  1. 1. Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs

    University dissertation from Clinical Sciences, Lund University

    Author : Christian Torbrand; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NPWT; negative pressure; vacuum-assisted closure; sternotomy wounds; deep sternal wound infection; mediastinitis; thoracic surgery; pressure transduction; neurohormones; neuropeptides; total heart volume variation; cardiac output; wound contraction; macrodeformation;

    Abstract : Negative pressure wound therapy (NPWT) has been widely adopted for the treatment of deep sternal wound infections due to its excellent clinical outcome. However, the mechanisms of action and effects on hemodynamics have not been thoroughly elucidated. READ MORE

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

    University dissertation from Otorhinolaryngology (Lund)

    Author : Sören Berg; [1997]
    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.

  3. 3. Clinical Electrocochleography in Menière´s disease

    University dissertation from Otorhinolaryngology (Lund)

    Author : Kornel Sass; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intrathoracic pressure; perilymphatic fistula; pressure exposure; endolymphatic hydrops; Menière´s disease; reproducibility; specificity; sensitivity; rarefaction click; condensation click; electrocochleography; summating potential; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. READ MORE

    University dissertation from Clinical Sciences, Lund University

    Author : Rainer Petzina; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Negative pressure wound therapy in cardiac surgery Rainer Petzina, M.D. Clinical Sciences, Lund, Lund University Poststernotomy mediastinitis is a devastating complication for patients undergoing cardiac surgery. READ MORE

  5. 5. Arterial pulse wave analysis. With special reference to vasoactive and anaesthetic drugs and to heart lung interactions

    University dissertation from Göteborg

    Author : Staffan Söderström; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pulse; blood pressure physiology; hypertension; aged; vasodilation; ventricular function; left; nitroglycerin; coronary disease; artificial respiration; fentanyl.;

    Abstract : In the young systolic arterial pressures (SAP) are higher in the radial artery than in the proximal aorta. Due to increased large artery stiffness and early pulse wave reflection aortic SAP increases more with age than peripheral SAP. READ MORE
