title: Parenchymal gas tensions in canine lung.
abstract: Lung parenchymal oxygen and carbon dioxide tensions were measured in dogs by using chronically implanted Silastic tubes. The effects of pulmonary arterial ligation and bronchial occlusion on lung tissue gases were recorded. Prevention of venous return to the lung increased parenchymal oxygen tension markedly. Obstruction of airways and bronchial arteries resulted in a profound decrease in parenchymal oxygenation.
