The mechanism of compensation for disorders of ventilation after pulmonary tissue resection is discussed. It is shown that these disorders are attended with reduction of arterial pulmonary blood flow and that angiospasm occurs in the postcapillary part of the vascular channel of pulmonary circulation. The compensatory effect is achieved by a right-to-right arteriovenous shunt which prevents extreme increase of pressure in the pulmonary artery in ventilation disorders.
本文探讨了肺组织切除术后通气障碍的代偿机制。研究表明，这些通气障碍伴随着肺动脉血流减少，且肺循环血管通道的毛细血管后段发生血管痉挛。其代偿作用是通过右向左动静脉分流实现的，这可防止通气障碍时肺动脉压力过度升高。
