The static limit of arterial blood pressure in the dog's hind limb.

Abstract

When the femoral artery is occluded in the anesthetized dog, the pressure in the distal segment usually declines progressively and approaches a static limit asymptotically. This static limit is independent of the original Degrees of vasomotor tone except under extreme conditions. It is concluded that the rapid supervention of reactive hyperemia in the dog vitiates the static limit as an index of vasomotor tone, unless an instantaneous method is developed for its estimation.
