[The effect of amplitude and frequency of pulse oscillations of blood flow on resistive and metabolic function of skeletal muscle vessels in cats].

The amplitude-frequency characteristics of the perfusion pressure, capillary hydrostatic pressure and the capillary filtration coefficient were nonlinear in acute experiments on cats. The shifts of the perfusion pressure and the capillary filtration coefficient could either increase or decrease depending on the range of the values of the amplitude and frequency of pulsing blood flow. The mean capillary hydrostatic pressure was also altering only in certain combinations of the pulsation amplitude and frequency. The maximal shifts of the hemodynamic parameters varied by the values of the amplitudes and frequencies at which they occurred.
