  1. 1. New methods for optimization of mechanical ventilation

    Författare :Peter Kostic; Peter Frykholm; Anders Larsson; Johan Petersson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mechanical ventilation; optoelectronic plethysmography; forced oscillation technique; laser interferometry; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Mechanical ventilation saves lives, but it is an intervention fraught with the potential for serious complications. Prevention of these complications has become the focus of research and critical care in the last twenty years. LÄS MER

  3. 2. Endotracheal Suction a Reopened Problem

    Författare :Birgitta Almgren; Marieann Högman; Mats Sjöquist; Anders Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Mechanical; ventilation; endotracheal; suction; lung; volume; loss; gas; exchange; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube. The tube needs to be cleaned from mucus by suction, which can cause negative effects such as lung collapse, hypoxemia and desaturation. LÄS MER

  4. 3. Evaluation of Respiratory Mechanics by Flow Signal Analysis : With Emphasis on Detecting Partial Endotracheal Tube Obstruction During Mechanical Ventilation

    Författare :Rafael Kawati; Michael Lichtwarck-Aschoff; Ulf Sjöstrand; Anders Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Complication: obstructed endotracheal tube; Equipment:endotracheal tube; Heart: cardiogenic oscillation; Respiratory mechanics: respiratory mechanics; Ventilation: controlled mechanical; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Sammanfattning : Evaluating respiratory mechanics during dynamic conditions without interrupting ongoing ventilation and flow, adds to the information obtained from the mechanics derived from static (= no flow) conditions, i.e., the flow signal has the potential to provide information on the properties of the respiratory system (including the tubing system).

  5. 4. Airway pressure release ventilation : A systematic experimental approach

    Författare :Peter Neumann; Uppsala universitet; []
    Nyckelord :Medical sciences; APRV; CPAP; atelectasis; recruitment; PEEP; inverse ratio ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Airway pressure release ventilation (APRV) is a ventilatory mode which allows unrestrictedspontaneous breathing (SB) throughout the ventilatory cycle. If SB is insufficient, mechanicalventilatory support is achieved by brief periodic decreases of the airway pressure below the CPAPlevel. LÄS MER

  7. 5. Modelling and Intelligent Climate Control of Buildings

    Författare :Mohsen Soleimani Mohseni; Bertil Thomas; Lennart Jagemar; Geoffrey Levermore; Chalmers University of technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; indoor climate control; operative temperature; demand controlled ventilation; prediction; feed-forward control;

    Sammanfattning : The main purpose of the work presented in this thesis is to examine the possibilities of different control techniques together with intelligent building technology to improve the indoor climate and/or the energy efficiency of buildings. In particular, the possibilities of measuring more variables and using them as input to the controllers are examined. LÄS MER
