Hypovolemia, which is a major cause of morbidity and mortality in sick foals, can occur rapidly as a result of several underlying disease processes.1,2 Fluid.

Influence of the Respiratory Cycle on Caudal Vena Cava Diameter Measured by Sonography in Healthy Foals: A Pilot Study M.C. Tuplin, A.E. Romero, and S.R. Boysen Background: Intravascular volume assessment in foals is challenging. In humans, intravascular volume status is estimated by the caudal vena cava (CVC) collapsibility index (CVC-CI) defined as (CVC diameter at maximum expiration [CVCmax] – CVC diameter at minimal inspiration [CVCmin])/CVCmax 9 100%. Hypothesis/Objectives: To determine whether the CVC could be sonographically measured in healthy foals, determine differences in CVCmax and CVCmin, and calculate inter- and intrarater variability between 2 examiners. We hypothesized that the CVC could be measured sonographically at the subxiphoid view and that there would be a difference between CVCmax and CVCmin values. Animals: Sixty privately owned foals
