WebJun 19, 2013 · Cardiac Output. Cardiac Output (CO) is the amount of blood the heart pumps from each ventricle per minute. It is usually expressed in litres per minute (L/min). CO = HR x SV. Changes in either HR or SV can alter CO. Impaired regulation of SV (including preload, afterload and contractility) can have a significant adverse affect on CO. WebDuring dynamic exercise, the force resisting ejection in the periphery (total peripheral resistance) is reduced by vasodilation, owing to the effect of local metabolites on the skeletal muscle vasculature. Thus, despite even a fivefold increase in cardiac output among normal subjects during exercise, mean arterial pressure increases only ...
