The examination of cardiovascular system in pilots in the process of their training has shown that the Valsalva test can execute the function of a slight or strong irritant with further changes in hemodynamics, particularly in the frequency of systoles and arterial pressure. These changes are accompanied by the shifts of cardiac volume per minute from hypo to hyper reaction. A correlation was disclosed between the reaction in the frequency of systoles and cardiac volume per minute which can be studied from the point of view of adaptation of blood circulation system to the factors of physical loads.
对飞行员训练过程中心血管系统的检查表明,瓦尔萨尔瓦试验可起到轻度或强烈刺激物的作用,进而引起血液动力学的变化,尤其是心搏频率和动脉血压的变化。这些变化伴随着每分钟心输出量从低反应到高反应的转变。在心搏频率反应与每分钟心输出量之间发现了一种相关性,这可以从血液循环系统对体力负荷因素的适应性角度进行研究。
