Under the effect of adrenaline upon the circulation system, vascular components of the blood pressure (BP) was shown to provide 75% of the maximal rise of the BP and the cardiac component--25%, whereas in response to noradrenaline the values were 62% and 38%, resp., in cats. In further development of systemic responses the role of cardiac component is enhanced whereas the role of vascular component becomes limited. Participation of the vascular component alone in systemic shift induced with catecholamines, under conditions of stabilised cardiac output, decreases the duration of the BP rise, whereas a combined rise of peripheral resistance and cardiac output in natural circulation provides an elongation of the BP changes.
在肾上腺素对循环系统的作用下，血压（BP）的血管成分在血压最大升高值中占75%，而心脏成分占25%；而在猫体内，去甲肾上腺素作用时，相应数值分别为62%和38%。在全身反应的进一步发展中，心脏成分的作用增强，而血管成分的作用则受到限制。在稳定心输出量的条件下，仅血管成分参与儿茶酚胺引起的全身变化，会缩短血压升高的持续时间，而在自然循环中，外周阻力和心输出量的联合升高则会延长血压变化的时间。
