The vasculature will leak too much and the mouse will get bloated - you'll see it first in either the intestines blowing up like a balloon or fluid coming out of the nose. Just not the same as the heart pumping when the mouse is alive with intact physiology and normal functioning. Don't know exactly why, but that's what happens when you go too fast. Perhaps the vasculature has lost its control to compensate for the pressure? I'm not a physiologist so I'm not sure why...maybe someone on the Histonet can answer that?

Merced

Why not?  What happens?  One would think the mammalian cardiovascular

That may be mouse cardiac output, but I can assure you, from experience,
you do not want to perfuse at 17ml/min.

Li,

Mouse cardiac output seems to be about 17 ml/min (e.g.
www.transonic.com/mice1.shtml), you probably want to try for that to
keep  pressures close to physiological.
A syringe pump is pretty inexpensive and probably all you need.
