  2. 1. 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).

  4. 2. Studies on ventilatory function in chronic neuromuscular disorders

    Author : Jan Weinberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ventilatory dysfunction; neuromuscular disorders; diaphragm; electromyogram; power spectrum; blood gas; ventilatory mechanics; sleep; polysomnography;

    Abstract : Ventilatory dysfunction is common in neuromuscular disorders (NMD). The present studies aimed at evaluating and developing methods for diagnosis of ventilatory function in NMD. Methods included were diaphragmatic EMG (EMGdi), blood gas monitoring assessed at rest and during exercise and nocturnal respiratory and sleep parameters. READ MORE

  5. 3. 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

  6. 4. Hemodynamic Effects of Lung Function Optimization in Experimental Acute Respiratory Distress Syndrome

    Author : Arnoldo Santos; Anders Larsson; Fernando Suarez-Sipmann; John Marini; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute respiratory distress syndrome; Lung protective ventilation; Mechanical ventilation; Open lung approach; Pulmonary heart disease; Pulmonary vascular mechanics; Pulmonary vascular dysfunction; Pulse wave analysis; Right ventricular dysfunction; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care; Fysiologi; Physiology;

    Abstract : Acute Respiratory Distress Syndrome (ARDS) is a severe pulmonary inflammation affecting thousands of patients every year in Sweden and has a mortality of 30-50%. Mechanical ventilation (MV) is usually necessary, but could per se augment the inflammation and contribute to mortality. READ MORE

  7. 5. Ventilatory-perfusion relationships and respiratory drive in chronic obstructive pulmanory disease : with special reference to hypoxaemia, sleep quality and treatment with inhaled corticisteroid

    Author : Karin Sandek; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : By measuring retention in blood and excretion in exhaled air of six infused inert gases using multiple inert gas technique (MIGET), it is possible to obtain detailed assessment of the ventilation-perfusion (VA/Q) relationships in patients with chronic obstructive pulmonary disease. Stable, non-bronchitic COPD patients show a substantial perfusion of hyper-ventilated lung regions. READ MORE
