  1. 6. Lung mechanics in the aging lung and in acute lung injury. Studies based on sinusoidal flow modulation

    Författare :Ulrika Bitzén; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostics; Diagnostik; acute lung injury; lung mechanics; acute respiratory distress syndrome; intensivvård; Anestesiologi; intensive care; Anaesthesiology; Andningsorganen; Respiratory system; Fysiologi; Physiology; flow regulation; method; lung resistance; compliance; aging;

    Sammanfattning : Knowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure interval.

  4. 8. The Effect of CO2-Pneumoperitoneum on Ventilation Perfusion Distribution of the Lung

    Sammanfattning : Laparoscopic operations are a common and popular way for abdominal procedures. They are usually performed by insufflation of carbon dioxide (CO2) into the abdominal cavity. However, insufflation of CO2 may interfere with cardiac and circulatory as well as respiratory functions. The CO2-pneumoperitoneum (PP) may cause hypercarbia and acidosis. LÄS MER

  5. 9. Titrating Open Lung PEEP in Acute Lung Injury : A clinical method based on changes in dynamic compliance

    Författare :Fernando Suarez Sipmann; Göran Hedenstierna; Hans Hedenström; Stefan Lundin; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; PEEP; open lung; recruitment; dead space; electrical impedance tomography; ARDS.; Medicine; Medicin;

    Sammanfattning : The recognition that supportive mechanical ventilation can also damage the lung, the so called ventilation induced lung injury (VILI), has revived the more than 40 year long debate on the optimal level of PEEP to be used. It is established that the prevention of VILI improves patient outcome and that PEEP exerts protective effects by preventing unstable diseased alveoli from collapsing. LÄS MER

  7. 10. Lung cancer in males : an epidemiological study in northern Sweden with special regard to smoking and occupation

    Författare :Lena Damber; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; case-control study; epidemiology; lung cancer; occupational risk; factors; smoking; radon; cell types; validity;

    Sammanfattning : In a case-control study comprising 589 cases of male lung cancer in northern Sweden longitudinal data concerning occupations, employments and smoking habits were collected by questionnaires.Pipe smoking was as common as cigarette smoking and gave very similar relative risk.
