[Pathophysiology after resections of the lung (author's transl)].

Measures of preventing postoperative lung atelectasis are discussed. The importance of total pre-operative smoking prohibition is stressed. Formula for pre-operative prediction of postoperative ventilation and pulmonary artery pressure are presented. Lung distention is not to be compared to lung emphysema. Lung distention may even improve ventilation as well as circulation of the remaining lung tissue.
