REACTIONS OF THE AORTA IN HEMORRHAGIC HYPOTENSION AND SHOCK

Abstract

On the basis of negative evidence from 3 modes of exptl. approach[long dash]viz., optical records of changes in aortic diam., measurements of changes in aortic circumference and pulse velocity studies at identical diastolic pressures[long dash]it appears highly improbable that active changes in the aortic wall play any role in the initiation or progression of hemorrhagic shock or in the establishment of an irreversible state.
