To provide a conceptual and clinical review of the physiology of the venous system as it is relates to cardiac function in health and disease.
An integration of venous and cardiac physiology under normal conditions, critical illness, and resuscitation.
The usual teaching of cardiac physiology focuses on left ventricular function. As a result of the wide array of shock states with which intensivists contend, an approach that takes into account the function of the venous system and its interaction with the right and left heart may be more useful. This two-part review focuses on the function of the venous system and right heart under normal and stressed conditions. The first part describes the basic physiology of the venous system, and part two focuses on the role of the venous system in different pathophysiologic states, particularly shock.
An improved understanding of the role of the venous system in health and disease will allow intensivists to better appreciate the complex circulatory physiology of shock and may allow for better hemodynamic management of this disorder.
提供静脉系统生理学的概念和临床综述，涉及健康和疾病中心脏功能的关系。
正常情况下、危重病和复苏期间静脉和心脏生理学的综合。
通常的心脏生理学教学侧重于左心室功能。由于重症监护医生所面临的广泛的休克状态，考虑到静脉系统的功能及其与右心和左心的相互作用的方法可能更有用。这两部分综述重点介绍正常和应激条件下静脉系统和右心的功能。第一部分描述了静脉系统的基本生理学，第二部分侧重于静脉系统在不同病理生理状态下的作用，特别是休克。
更好地了解静脉系统在健康和疾病中的作用，将使重症监护医生更好地理解休克的复杂循环生理学，并可能改善对这种疾病的血流动力学管理。
