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

    Author : Ulrika Bitzén; Lund Klinisk fysiologi; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Artificial Neural Networks (ANN) in the Assessment of Respiratory Mechanics

    Author : Gaetano Perchiazzi; Göran Hedenstierna; Björn Jonson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; artificial neural networks; respiratory system compliance; respiratory system resistance; respiratory system time constant; intrinsic positive end expiratory pressure; PEEPi; animal model; acute lung injury; oleic acid; Otis model; Fysiologi; Physiology; Fysiologi;

    Abstract : The aim of this thesis was to test the capability of Artificial Neural Networks (ANN) to estimate respiratory mechanics during mechanical ventilation (MV). ANNs are universal function approximators and can extract information from complex signals. READ MORE

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

    Author : Rafael Kawati; Michael Lichtwarck-Aschoff; Ulf Sjöstrand; Anders Larsson; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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).

  7. 5. The dynostatic algorithm in adult and paediatric respiratory monitoring

    Author : Sören Söndergaard; Göteborgs universitet; []
    Keywords : monitoring; respiratory mechanics; lung model; fibre optic pressure measurement; alveolar pressure; dynostatic algorithm;

    Abstract : Introduction: Positive pressure ventilation carries a risk of aggravating systemic and lung disease. Monitoring of ventilatory pressure and volume is important to minimize this risk. Conventionally, the pressure of the respiratory system is measured outside the patient. READ MORE
