The pulmonary gas exchange was studied in 148 patients with prosthesis of the cardiac valves during progressing cardiac insufficiency. It was established that with the increase of cardiac insufficiency respiratory disorders also increase, mainly at the expense of the increase of the intrapulmonary arterio-venous shunting of the blood. The use of artificial lung ventilation with positive expiratory pressure in the post-operative period decreases intrapulmonary shunting, thus increasing the partial pressure and oxygen saturation of the arterial blood, and does not exert depressing action on the cardiac activity.
对148例心脏瓣膜置换术后出现进行性心功能不全的患者进行了肺气体交换研究。结果表明，随着心功能不全的加重，呼吸障碍也会增加，主要是由于肺内动静脉血液分流增加所致。术后使用呼气末正压人工肺通气可减少肺内分流，从而提高动脉血的分压和氧饱和度，且对心脏活动无抑制作用。
