| Dlood motion in big arterial vessels in considered in the work. The impulse motion of blood in the elastic vessel is modelled by the telegraph equation. Appication of the Bessel-Ostroumov phenomenon consisting in dependence of the pressure on the vessel defermation velocity allows to explain increasing the pulse wave amplitude with moving off from a heart. An analytical solution is in good agreement with experimental results of other authors. Jdtained results may be used both for diagnostics of the circulatory system and for prosthesis of the vessels. |
