  1. 16. Lung aeration and pulmonary gas exchange during general and epidural anaesthesia : Influenced by inspired oxygen concentration and diaphragm shape

    Författare :Adrian Reber; Uppsala universitet; []
    Nyckelord :Medical sciences; Anesthesia: epidural; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Induction of general anaesthesia causes a rapid decrease in functional residual capacity, which can promote alveolar collapse (atelectasis) and airway closure in dependent lung regions. Mismatching of ventilation and perfusion (VA/Q) in the lungs is accompanied by impairment of pulmonary gas exchange. LÄS MER

  3. 17. Aspects of lung mechanics during mechanical ventilation

    Författare :Magni Gudmundsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute respiratory failure; Acute respiratory distress syndrome; Mechanical ventilation; Transpulmonary pressure; Expiratory time constant; Esophageal pressure;

    Sammanfattning : Background: One of the most common diagnoses in the intensive care unit is acute respiratory failure. In its most severe form it is called acute respiratory distress syndrome and often requires mechanical ventilation. LÄS MER

  4. 18. Stereotactic body radiation therapy of lung tumours : clinical and dosimetric aspects

    Författare :Kristin Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The general aim of this thesis was to increase the knowledge regarding some clinical and methodological aspects, relevant in view of toxicity as well as tumour control, in stereotactic body radiation therapy (SBRT) of lung tumours. In the first two studies, reirradiation and radiation-induced atelectasis were studied. LÄS MER

  5. 19. High frequency jet ventilation (HFJV) in clinical practice

    Författare :Karolina Galmén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Surgery often requires general anaesthesia. During general anaesthesia, a ventilator is often used to secure the breathing of the patient. This is preferably done by mimicking normal ventilation. LÄS MER

  7. 20. Clinical implementation of Pulsed inhaled Nitric Oxide in equine anaesthesia

    Författare :Maja Wiklund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Hypoxaemia is a common complication during horse anaesthesia that is a challengeto treat. The primary cause of hypoxaemia is the development of a large intrapulmonaryshunt that leads to significant ventilation-perfusion mismatch. Openingand ventilating atelectasis during anaesthesia requires high airway pressures andrepeated manoeuvres. LÄS MER
