WebHigh CVP values reflect overhydration, increased venous return or right sided cardiac failure. Mean Arterial Pressure (MAP): Reflects changes in the relationship between cardiac output (CO) and systemic vascular resistance (SVR) and reflects the arterial pressure in the vessels perfusing the organs. 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. cumberland league
