Guyton和他的同事(Guyton 1963；Guyton，Jones和Coleman 1973)通过实验打开下腔静脉和右心房交界处的环，分析了闭合循环环中心输出量的调节。由于心输出量曲线刻画了心脏作为泵的性能，静脉回流曲线表示血管系统特性和循环血容量，他们将这两条关系曲线叠加在一起，证明了自然闭合条件下的心输出量在它们的交点处。虽然这一概念有助于分析在闭合循环系统中支配心输出量的全球机制，但它不允许将循环系统的各个心腔和肺血管组件的贡献分开。
Guyton and his associates (Guyton 1963; Guyton, Jones, and Coleman 1973) analyzed the regulation of cardiac output in the closed circulatory loop by experimentally opening the loop at the junction of the vena cava and the right atrium. Reasoning that the cardiac output curve depicts the performance of the ventricle as a pump and the venous return curve represents vascular system properties and circulatory blood volume, they superimposed these two relationship curves and showed that cardiac output in the natural closed-loop condition is found at their intersection. Although this concept was useful in analyzing the global mechanisms that govern cardiac output in the closed circulatory system, it did not allow separation of the contributions of the individual cardiac chambers and the pulmonary vascular components of the circulatory system.
