Aortic impedance responds to volume and tone shifts in animals; hypothesis-generating for human hemodynamics with no clinical implications yet.
Changes in aortic smooth muscle tone significantly alter aortic characteristic impedance, which may play a role in hemodynamic adjustments to hemorrhage and volume expansion.
Stone et al. (1984) studied this question.
