Effects of hypoxic hypoxia, statokinetic stimuli, breathing O2 at excessive pressure, hypodynamia, and loads on the human body were studied with rheoencephalographic, rheovasographic and rheopneumographic techniques. The data obtained allows to conclude that rheography is an adequate and highly informative method for assessment of systemic hemodynamics in humans. More pronounced shifts in the circulation system in response to air and space flight factors occurred in head-down position and when breathing O2 at excessive pressure. The key mechanism controlling hemodynamics in altered environment was modulation of tone in cerebral and peripheral vessels. Rheographic, amplitude rate, dicrotic and diastolic indices can be referred to as parameters which most fully describe systemic hemodynamics.
采用脑血流图、血管血流图和呼吸血流图技术，研究了低氧性缺氧、动力运动刺激、高压吸氧、体力活动不足及负荷对人体的影响。所获数据表明，血流图检查是评估人体全身血流动力学的一种充分且信息丰富的方法。头低位以及高压吸氧时，循环系统对航空航天飞行因素的反应变化更为明显。在变化环境中控制血流动力学的关键机制是调节脑血管和外周血管的张力。血流图、振幅率、重搏波和舒张期指标可作为最全面描述全身血流动力学的参数。
