The dynamics and amplitude of changes in venous return and right atrial pressure (central venous pressure) in response to pressor stimuli were studied in acute experiments on cats. The increase in venous return was accompanied by either increase, or decrease in the central venous pressure. Thus, shifts in systemic venous return were not accompanied by simultaneous and co-directed changes in the central venous pressure. These findings suggest the absence of a direct relationship between these parameters.
在对猫进行的急性实验中，研究了静脉回流量和右心房压力（中心静脉压）对升压刺激反应的动态变化和幅度。静脉回流量增加时，中心静脉压要么升高，要么降低。因此，体循环静脉回流量的变化并未伴随中心静脉压同时同向变化。这些发现表明这些参数之间不存在直接关系。
