The ultrasonic method was used in acute experiments on cats with open chest and under artificial lung ventilation to study the coronary circulation, the minute and stroke volumes of the heart during changes in gaseous medium. Hypoxic hypoxia and hypercapnia were demonstrated to induce a considerable increase in the coronary circulation in the presence of a slightly elevated minute volume of the heart. The authors assume that the induced changes in the phasic coronary circulation point to the increased resistance of the coronary vessels to mechanical compression during systoles.
采用超声法对开胸并进行人工肺通气的猫进行急性实验，以研究气体介质变化时的冠状动脉循环、心脏的每分输出量和搏出量。结果表明，在心脏每分输出量略有升高的情况下，低氧性缺氧和高碳酸血症可导致冠状动脉循环显著增加。作者认为，冠状动脉循环的阶段性变化表明，在收缩期冠状动脉血管对机械压迫的阻力增加。
