    Sammanfattning : Clusters are finite ensembles of atoms or molecules with sizes in the nanometer regime (i.e. nanoparticles). This thesis present results on the geometric and electronic structure of homogeneous and heterogeneous combinations of atoms and molecules. LÄS MER

  3. 2. Evaluation and development of a capnodynamic method for estimation of pulmonary blood flow in a porcine model

    Författare :Caroline Hällsjö Sander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cardiac output;

    Sammanfattning : Effective pulmonary blood flow (EPBF) i.e. cardiac output (CO) minus shunt flow could be estimated by a capnodynamic equation. Via introduction of short pauses in the ventilatory pattern the required alterations of carbon dioxide are induced. LÄS MER

  4. 3. Psychomotor and cardiorespiratory functions during inert gas sedation

    Författare :Anders Östlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :arterial baroreflex; heart rate; gas density; hyperbaric bradycardia; inert gas; inspiratory loading; narcosis; nitrous oxide; sedation; ventilation;

    Sammanfattning : Relative hypoventilation and bradycardia are commonly observed in both resting and exercising divers. Divers are exposed to a complex environment where there are increases of hydrostatic pressure, gas density and partial pressure of sedating inert gas. LÄS MER
