  1. 1. Pulmonary Atelectasis in General Anaesthesia Clinical Studies on the Counteracting Effects of Positive End-Expiratory Pressure

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erland Östberg; Uppsala universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General anaesthesia; pulmonary atelectasis; positive end-expiratory pressure; oxygen; computed tomography; continuous positive airway pressure; mechanical ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Partial lung collapse, i.e., pulmonary atelectasis, is common during general anaesthesia. The main causal mechanism is reduced lung volume with airway closure and subsequent gas absorption from preoxygenated alveoli. READ MORE

  2. 2. Positive end-expiratory pressure ventilation and cardiac performance : an experimental study in the pig

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jan Erik Berglund; Uppsala universitet.; [1991]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

  3. 3. Lung and chest wall properties during mechanical ventilation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Per Erik Persson; Göteborgs universitet.; Gothenburg University.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Respiratory mechanics; Esophageal pressure; Positive end-expiratory pressure;

    Abstract : Background: Mechanical ventilation causes injury to the lungs due to high pressures and high volumes. Pressure affecting the lungs, the transpulmonary pressure, needs to be monitored to minimise harmful side effects but then lung and chest wall mechanics need to be separately considered. READ MORE

  4. 4. Gas Exchange in the Normal Lung Experimental studies on the effects of positive end-expiratory pressure and body position

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Mats J. Johansson; Linköpings universitet.; Linköpings universitet.; Östergötlands Läns Landsting.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : BACKGROUND: The principal function of the lung is gas exchange requiring adequate ventilation and perfusion at the level of the alveoli. The efficiency of gas exchange is depending on the distributions of regional ventilation (V) and pulmonary blood flow (Q) and their correlation. READ MORE

  5. 5. A Laparoscopic Approach in Gastro-Oesophageal Surgery Experimental and Epidemiological Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rune Sandbu; Uppsala universitet.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Gastro-oesophageal surgery; fundoplication; laparoscopy; long-term results; pneumothorax; intra-cranial pressure; positive end-expiratory pressure; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; Surgery; kirurgi;

    Abstract : The extension of laparoscopic procedures into the chest may induce specific pathophysiologic effects.In pigs, we have demonstrated how devastating a combined thoraco-laparoscopic approach can be for gas exchange. Furthermore, the transmission of elevated pressure intra-cranially is a potential danger. READ MORE
