reason, this formula has been used to obtain blood flow from the
second is the equation
continuity to describe
incompressibility of the fluid:
or that blood flow velocity gradient is related to the rate of change in
cross-sectional area of the blood vessel.
a cylindrical blood vessel,
the cross-sectional area
is related to its inner lumen radius r, as
properties of the vessel wall
The third equation is the equation of state to describe the elastic
is a constant.
From this set of equations, the wave equation is obtained as:
Which gives the wave velocity
This equation also provides a means to obtain pulse wave velocity from
the simultaneous measurements of pressure and diameter. Define
