Abstract

When native blood flow through the aorta from the adult heart and lungs meets retrograde blood flow from an artificial heart and lung during venoarterial extracorporeal membrane oxygenation (VA-ECMO), the result is the creation of two separate circulations on either side of the blood flow mixing point. This phenomenon is known as dual circulation and is characterized by different content of oxygen and carbon dioxide between the circulations. There is currently a lack of clarity surrounding the nomenclature to describe this physiologic phenomenon in VA-ECMO and thus we endeavor to name and define these terms to facilitate clear communication and proper clinical management of these patients.

摘要

当来自成人心脏和肺部的原生血流在静脉-动脉体外膜肺氧合（VA-ECMO）期间遇到来自人工心脏和肺的逆行血流时，结果是在血流混合点的两侧创建两个单独的循环。这种现象称为双重循环，其特征在于循环之间的氧气和二氧化碳含量不同。目前，VA-ECMO 中描述这种生理现象的命名法尚不清楚，因此我们努力对这些术语进行命名和定义，以方便对这些患者进行清晰的沟通和适当的临床管理。
