It's been a while since I reviewed
the entire paper but your right - there are a lot of things that alter velocity
in an extremity artery - with volume flow being the primary one. There are
several things that affect flow to the extremities and if the flow changes, so
will the velocity. This is why I really don't look at the absolute
PSV in a peripheral vessel but was wondering what others thought.

Does the paper mention anything about cardiac output? If the pump isn't
working well, the velocities will be lower due to decreased perfusion.
