  1. 1. Lung function after cardiac surgery : With special reference to atelectasis and ventilation-perfusion relationships

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Arne Tenling; Uppsala universitet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac surgery; thoracic epidural analgesia; vital capacity manoeuvre; computed tomography; ventilation-perfusion relationships; gas exchange; atelectasis; respiratory inductive plethysmography; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; anestesiologi; Anaesthesiology;

    Abstract : Patients undergoing cardiac surgery were investigated before and after the operation.Ventilation-perfusion (VA/Q) relationships were examined by the multiple inert gas elimination method, and atelectasis and aeration of the lungs were examined by computedtomography (CT). READ MORE

  2. 2. 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; Mats Enlund; Lennart Edmark; Sophie Lindgren; [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

  3. 3. Open lung concept in high risk anaesthesia Optimizing mechanical ventilation in morbidly obese patients and during one lung ventilation with capnothorax

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Reinius; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesia; mechanical ventilation; atelectasis; morbidly obese; one-lung ventilation; PEEP; recruitment maneuver; spirometry; EIT; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Formation of atelectasis, defined as reversible collapse of aerated lung, often occurs after induction of anaesthesia with mechanical ventilation. As a consequence, there is a risk for hypoxemia, altered hemodynamics and impaired respiratory system mechanics. READ MORE

  4. 4. Effects of Deep Breathing Exercises after Coronary Artery Bypass Surgery

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elisabeth Westerdahl; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical therapy; atelectasis; breathing exercises; coronary artery bypass; computed tomography; physiotherapy; postoperative care; postoperative complications; respiratory function tests; thoracic surgery; Sjukgymnastik; INTERDISCIPLINARY RESEARCH AREAS Caring sciences Physiotherapy; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vårdvetenskap Sjukgymnastik fysioterapi;

    Abstract : Deep breathing exercises are widely used in the postoperative care to prevent or reduce pulmonary complications, but no scientific evidence for the efficacy has been found after coronary artery bypass grafting (CABG) surgery. The aim of the thesis was to describe postoperative pulmonary function and to evaluate the efficacy of deep breathing exercises performed with or without a blow bottle device for positive expiratory pressure (PEP) 10 cmH2O or an inspiratory resistance-positive expiratory pressure (IR-PEP) mask with an inspiratory pressure of -5 cmH2O and an expiratory pressure of +10 to +15 cmH2O.

  5. 5. Clinical and laboratory studies on propofol

    University dissertation from Linköping : Linköpings universitet

    Author : Anders Gadegaard Jensen; Linköpings universitet.; Linköpings universitet.; [1993]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atelectasis; bowel function; rat neurons; cytoskeleton; cytosolic calcium; haemodynamic stability; human glial cells; leucocytes; propofol; recovery assessment; MEDICINE; MEDICIN;

    Abstract : Patients undergoing major abdominal surgery were randomly given total intravenous anaesthesia based on propofol and fentanyl, anaesthesia based on propofol, fentanyl and nitrous oxide or anaesthesia based on isoflurane and fentanyl. Postoperative atelectasis demonstrated by computed tomography of the chest was found to a similar extent and a similar decrease in arterial oxygen pressure was seen in the groups. READ MORE
