  1. 21. Echocardiographic methods for assessment of coronary artery disease

    Författare :Peter Blomstrand; Lars-Åke Brodin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Upright bicycle exercise echocardiography with digital image acquisition in seated position during exercise and in recumbent position before and immediately after exercise was performed in 66 men, one month after an episode of unstable coronary arte1y disease. It was difficult to obtain images of adequate quality during exercise but new or worsening of wall motion abnormalities not seen in recumbent position after exercise were detected at peak-exercise in patients with good image quality.

  3. 22. Sleep disordered breathing and hemodynamic function

    Författare :Ludger Grote; Göteborgs universitet; []
    Nyckelord :sleep apnea; hypertension; blood pressure; vascular function; exercise; arousal;

    Sammanfattning : This thesis addresses the association between sleep disordered breathing (SDB) and hemodynamic function. A cross sectional study in a sleep laboratory cohort (n=1190) demonstrated a dose-response relationship between the severity of SDB, expressed as respiratory disturbance index (RDI), and office blood pressure, heart rate, and the risk of hypertension.

  4. 23. Cardiovascular risk factors and peripheral vascular function in lung transplant recipients

    Författare :Martin Silverborn; Göteborgs universitet; []
    Nyckelord :lung transplantation; cardiovascular risk factors; hypertension; arterial compliance; vascular resistance; endothelial function; endothelin-1;

    Sammanfattning : Objective: Cardiovascular disease is a major contributor to morbidity and mortality after organ transplantation. Development of cardiovascular risk factors, like hypertension, is common after transplantation. LÄS MER

  5. 24. Jet Ventilation for Airway Surgery : The Influence of Mode and Frequency on Ventilation Efficacy

    Författare :Robert Sütterlin; Peter Frykholm; Anders Larsson; Ullman Johan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; jet ventilation; airway obstruction; tracheal stenosis; HFJV; SHFJV; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : In surgery for airway obstruction, the anesthetist and the ear-nose-throat surgeon share the approach to the airway and jet ventilation (JV) is a mutually convenient ventilation technique for both parties. As a consequence of the open system jet ventilation is applied in, bedside measurements of lung volumes are cumbersome to perform and thus, there is a lack of studies comparing different modes of JV or investigating the influence of ventilator settings on lung volumes and gas exchange.

  7. 25. Respiratory and cardiovascular responses to diesel exhaust exposure

    Författare :Håkan Törnqvist; Joel Kaufman; Umeå universitet; []
    Nyckelord :lungmedicin; Lung Medicine;

    Sammanfattning : Background: Exposure to traffic-derived air pollution is associated to high incidence of respiratory and cardio-vascular morbidity and mortality. Diesel engines and fossil fuel contribute to a great amount to the ambient particulate matter pollution. LÄS MER
