title: [Organ vessel functions by pulsatile flow].
abstract: It was found that changes of resistance, capacity and exchange vessel functions of the skeletal muscle depended on values of amplitude and frequency of perfusion blood flow in acute experiments on cats. Amplitude-frequency characteristics of hemodynamic parameters of these functions were nonlinear. Ranges of amplitude and frequency variation with significant shifts of these parameters were determined. Conditions of perfusion (constant flow or constant pressure) changed volume and direction of haemodynamic parameter shifts under the amplitude-frequency modulation of the pulsatile blood flow. The pulsatile blood flow oscillations exerted maximum influence on hemodynamic parameters of exchange vessel function. The author has proposed the wave regulation conception of organ vessel functions.
