Fick equation for cardiac output
WebThus, the Fick principle involves the blood oxygenation process through the lungs and oxygen delivery to the tissues, where it is added and removed by a flow limited mechanism. By measuring the amount of oxygen carried by the blood, the total amount of blood needed to carry oxygen through the lungs could be calculated. WebDec 2, 2024 · The Fick’s principle states that oxygen consumption is the product of cardiac output (CO) and the arteriovenous oxygen difference (CaO2 minus CVO2). In the setting of a fixed cardiac output, increased oxygen demand results in an increased arteriovenous oxygen difference, and with reduced oxygen demand the arteriovenous oxygen …
