1. Pulmonary Atelectasis in General Anaesthesia : Clinical Studies on the Counteracting Effects of Positive End-Expiratory Pressure
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. Reducing Atelectasis during General Anaesthesia – the Importance of Oxygen Concentration, End-Expiratory Pressure and Patient Factors : A Clinical Study Exploring the Prevention of Atelectasis in Adults
Abstract : Background: The use of pure oxygen during preoxygenation and induction of general anaesthesia is a major cause of atelectasis. The interaction between reduced lung volume, resulting in airway closure, and varying inspiratory fractions of oxygen (FIO2) in determining the risk of developing atelectasis is still obscure.

3. Atelectasis and gas exchange impairment after cardiopulmonary bypass : An experimental study
Abstract : Despite of the improvement in management and equipment for cardiopulmonary bypass (CPB), postoperative pulmonary complications remain a major problem after cardiac surgery. In the present thesis, using a pig model, atelectasis has been tested as a cause of the increase in intrapulmonary shunt commonly seen after CPB. READ MORE

4. Lung aeration and pulmonary gas exchange during general and epidural anaesthesia : Influenced by inspired oxygen concentration and diaphragm shape
Abstract : 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. READ MORE

5. Stereotactic body radiation therapy of lung tumours : clinical and dosimetric aspects
Abstract : 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. READ MORE
