  2. 21. Regional pulmonary vasoreactivity, with special reference to nitric oxide, prostacyclin and body posture

    Author : Danguolé Rimeika; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Regional pulmonary perfusion; nitric oxide; prostacyclin; NOS-inhibition; COX-inhibition; shunt; one-lung ventilation;

    Abstract : The primary aim of the study was to investigate possible mechanisms behind the improved arterial oxygenation in ventilator-treated patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) when turned into prone position. A secondary aim was to discover new knowledge of possible importance for treatment of patients with oxygenation problems in intensive care and during anesthesia. READ MORE

  4. 22. Chronic obstructive pulmonary disease. Aspects of smoking, biomarkers and cardiovascular disease

    Author : Morten Kraen; Malmö Klinisk fysiologi och nuklearmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Chronic obstructive pulmonary disease (COPD) is a common and preventable disease characterized by airflow obstruction and emphysema development. COPD often coexist with cardiovascular disease (CVD) and both diseases have common risk factors i.e. age and smoking and shared features i. READ MORE

  5. 23. Pulmonary ventilation and perfusion assessed by electrical impedance tomography - Experimental studies in pigs

    Author : Anneli Fagerberg; Göteborgs universitet; []
    Keywords : electrical impedance tomography; V Q matching; pig; endotoxinaemic ALI; ACE inhibitor;

    Abstract : Pulmonary ventilation and perfusion and ventilation/perfusion (V/Q) matching determine gas exchange in every lung unit in the healthy state and in the pathologically altered lung. Mismatch of V and Q lead to hypoxaemia and hypercapnia and monitoring of V/Q relations are thus important in critical illness. READ MORE

  6. 24. Mesenchymal heterogeneity in the adult human lung

    Author : Måns Kadefors; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lung; Extracellular matrix; Adventitia; Fibroblast; mesenchymal cell; Alveolar epithelial cell; Fibrosis; Idiopathic pulmonary fibrosis; Mass spectrometry; RNA-sequencing;

    Abstract : The human lung is a complex tissue consisting of a heterogeneous mix of different structures and cells, each which a specific role that together contribute to the primary function of the organ: the gas exchange. Different mesenchymal cells populate the interstitial areas around airways and blood vessels and form the connective tissue together with the extracellular matrix. READ MORE

  7. 25. The Effect of CO2-Pneumoperitoneum on Ventilation Perfusion Distribution of the Lung

    Author : Christof Strang; Göran Hedenstierna; Suzanne Odeberg-Wernerman; Uppsala universitet; []
    Keywords : lung; atelectasis; computed tomography; multiple inert gas elimination technique; model; pig; Pa–ECO2 ratio; surgery; laparoscopy; lung; blood flow; single photon emission computed tomography; ventilation perfusion distribution; gas exchange; hypoxic pulmonary vasoconstriction; MEDICINE; MEDICIN;

    Abstract : 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. READ MORE
