The role of "arterial reservoir" (AR) has been assessed experimentally in 20 mongrel dogs during the onset of acute heart failure (AHF) and in left ventricular bypass (LVB). The criteria evaluating AR function were as follows: diameter and volume of aorta filling (dA; VA), aortic wall distensibility (D). Va in the range of BPm 30.4 to 171 mm Hg changed from 12.62 to 49.32 ml, i.e. two-three-fold. D at maximum and minimum BRm values decreased by 10 and more times. A direct correlation between relative Va and da changes with a coefficient 2 has been observed in any aortic section. BPm (but not BPsy st or BPdia st which characterizes a degree of "tense" AR filling can serve as an adequate index of LVB efficacy.
在20只杂种犬急性心力衰竭（AHF）发作期间及左心室旁路（LVB）过程中，对“动脉储器”（AR）的作用进行了实验评估。评估AR功能的标准如下：主动脉充盈直径和容积（dA；VA）、主动脉壁扩张性（D）。在平均血压（BPm）30.4至171 mmHg范围内，VA从12.62 ml变化至49.32 ml，即增大了两到三倍。最大和最小BRm值时的D降低了10倍及以上。在任何主动脉节段均观察到相对VA与dA变化之间存在系数为2的直接相关性。BPm（而非表征“紧张”AR充盈程度的收缩期血压或舒张压）可作为LVB疗效的充分指标。
