By means of regional rheography and electrocardiography cardiovascular reactions to LBNP (25 mm Hg--2 min; 35 mm Hg--3 min; 40 mm Hg--5 min; 50 mm Hg--5 min) were studied in 60 young male test subjects (aged 25--42). Changes in the content and excretion of catecholamines were followed before and after LBNP in II test subjects. The investigations helped to elucidate mechanisms of compensatory and related reactions of the cardiovascular and sympathoadrenal systems. Diagnostic and prognostic criteria to evaluate LBNP tolerance were established. The criteria can be used to assess functional capabilities of the cardiovascular system and to predict orthostatic tolerance of cosmonaut candidates.
通过区域血流图和心电图研究了60名年轻男性受试者(年龄25 - 42岁)对下体负压(25毫米汞柱 - 2分钟;35毫米汞柱 - 3分钟;40毫米汞柱 - 5分钟;50毫米汞柱 - 5分钟)的心血管反应。对2名受试者在下体负压前后儿茶酚胺的含量和排泄变化进行了跟踪。这些研究有助于阐明心血管和交感肾上腺系统的代偿及相关反应机制。建立了评估下体负压耐受性的诊断和预后标准。这些标准可用于评估心血管系统的功能能力,并预测宇航员候选人的直立耐受性。
