Peripheral Venoconstriction During Acceleration and Orthostasis
Active peripheral venous constriction has been demonstrated in dogs by a miniature balloon technic. The magnitude of the venoconstrictor response to acceleration on the centrifuge was strongly correlated with the animal's ability to maintain arterial pressure, suggesting the importance of contraction of the venous reservoir in the support of cardiac output under a hydrostatic load.
