1. Pulmonary Atelectasis in General Anaesthesia : Clinical Studies on the Counteracting Effects of Positive End-Expiratory Pressure
Sammanfattning : 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. LÄS MER
2. Positive end-expiratory pressure ventilation and cardiac performance : an experimental study in the pig
Sammanfattning : .... LÄS MER
3. Gas Exchange in the Normal Lung : Experimental studies on the effects of positive end-expiratory pressure and body position
Sammanfattning : 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. LÄS MER
4. Lung and chest wall properties during mechanical ventilation
Sammanfattning : 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. LÄS MER
5. A Laparoscopic Approach in Gastro-Oesophageal Surgery : Experimental and Epidemiological Studies
Sammanfattning : 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. LÄS MER
