In experiments on dogs it was shown that on the basis of the dynamics of circulatory parameters it is possible to divide the erectile phase of traumatic shock into two periods. The first period, similar to "defence reactions" in dangerous situations and under the action of potent non-specific stimuli, is characterized by an increased blood inflow to the myocardium, rise in the cardiac output and reduction of the tonus in peripheral vessels. The second period is characterized by the beginning of decompensation of the cardiovascular system. It is completed by the development of the torpid phase of shock.
