Pressure wave propagation in arteries. A model with radial dilatation for simulating the behavior of a real artery

The authors solve the equation of pressure wave propagation in an artery with radial dilatation to give an analytic solution of wave propagation in an elastic vessel for more generalized conditions. This will serve as a complementary solution to work that is based on the assumption that the radial dilatation of the arterial wall is small. The authors´ solution is important for physiological studies because it simulates the behavior of a real artery. To confirm the authors´ analytic solution, experiments were performed in tubes with different elastic constants.
