[Simulation model of local mechanisms controlling the human systemic circulation vessels during postural tests].
The article describes a nonpulsatile model of human systemic circulation simulating the effects of posture changes on main indices of blood flow in different vessels and body segments. The model comprises the hemodynamics structural chart, hydrodynamic and hydrostatic circulation models, and a myogenic regulation model The systematic circulation model enables investigation and representation of myogenic regulation of peripheral circulation along different vessels and body segments experimental investigations of which is complicated by inevitable nonlinear distortions. In future an algorithm will be developed to compute values of the main hemodynamic indices for the tilt and standing tests.
