The interaction of the heart and lungs is probably the most important aspect of life and survival. Fortunately, it is not difficult to understand the fundamentals. The purpose of the lungs and their ventilation is to present oxygen to the circulation via the alveoli and to receive carbon dioxide from the circulation and then expel it. The relations of the heart and lungs and the matching of blood flow to the various organs with ventilation and lung perfusion may be disrupted by a variety of congenital or acquired heart malformations. They include those giving rise to an increased or reduced pulmonary blood flow, elevated pulmonary venous pressure or external physical pressure on the airways or lung parenchyma. Respiratory disorders which compromise cardiac function include states with reduced alveolar ventilation, those with a barrier to ventilation or perfusion, ventilation/perfusion mismatch and pulmonary vascular disease. There is also a fascinating group in which congenital disorders of the heart and lung co-exist to produce very particular modes of abnormal cardiopulmonary interaction.

心脏和肺部的相互作用可能是生命和生存中最重要的方面。幸运的是,了解基本面并不难。肺及其通气的目的是通过肺泡向循环提供氧气,并从循环中接收二氧化碳,然后将其排出。各种先天性或后天性心脏畸形可能会破坏心脏和肺的关系以及通过通气和肺灌注与各个器官的血流匹配。其中包括引起肺血流量增加或减少,肺静脉压力升高或气道或肺实质的外部物理压力。损害心脏功能的呼吸系统疾病包括肺泡通气减少,通气或灌注障碍,通气/灌注不匹配和肺血管疾病的状态。还有一个令人着迷的群体,其中心脏和肺的先天性疾病并存,产生异常心肺相互作用的非常特殊的模式。
