Pulmonary arterial pressure and gas exchange during thoracotomy
Uptake of oxygen and elemination of carbon dioxide depend on alveolar ventilation, pulmonary blood flow and a suitable regional distribution of ventilation in relation to blood flow. Thoracotomy influences on all these factors in a complicated manner. Results obtained from patients undergoing lung surgery can therefore be difficult to interpret, but on the other hand the use of endobronchial tube gives a physiologically interesting opportunity to measure ventilation-perfusion relationships of a defined region, namely, that of each lung.
