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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gaetano Perchiazzi; Göran Hedenstierna; Björn Jonson; [2004]
    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; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi 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

  3. 3. Home Mechanical Ventilation in Sweden. Demography, Indications, Clinical Effects and Survival

    University dissertation from Department of Respiratory Medicine and Allergology, Lund University

    Author : Michael Laub; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; home mechanical ventilation; Andningsorganen; Respiratory system; causes of death; selection criteria; clinical effects; prevalence; temporal changes; survival; Chronic respiratory failure hypoventilation;

    Abstract : Home mechanical ventilation in patients with chronic respiratory failure secondary to several different diseases has become widely acceptable as the provision of ventilatory support can provide symptomatic relief and increase life expectancy. Aims: To study the selection criteria underlying the initiation of home mechanical ventilation and to quantify the effects of in relation to blood gases and lung function; to examine temporal changes in treatment prevalence in Sweden; to study survival and causes of death and demonstrate possible related impact factors.

  4. 4. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mariangela Pellegrini; Anders Sune Larsson; Göran Hedenstierna; Michael Quintel; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute respiratory distress syndrome; artificial respiration; diaphragm; pulmonary atelectasis; lung imaging; respiratory system; animal model; Fysiologi; Physiology; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Despite being an essential life-support strategy in severe respiratory failure, mechanical ventilation can, if not optimally set and monitored, lead to injury of the lung parenchyma and diaphragm. These conditions are called ventilator-induced lung injury and ventilator-induced diaphragmatic dysfunction (VIDD), respectively. READ MORE

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

    University dissertation from Department of Clinical Physiology, Lund University

    Author : Ulrika Bitzén; [2006]
    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.
