Pohl, C. Beck and G. Noeldge-Schomburg. European Journal of Anaesthesiology. Published online: 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 … WebCalculation of AV oxygen difference and cardiac output using the Fick method Oxygen consumption is estimated from a nomogram based on age, sex, height, and weight.

WebJan 20, 2024 · Logically, that principle is called the Fick principle. Rearranging the equation: CO = VO2 / (Ca - Cv) where VO2 is the total oxygen consumption, as a volume per unit time (eg. L/min) CO is the cardiac output, also as volume per unit time (L/min) Ca and Cv are the arterial and venous oxygen content (eg. ml/L) WebIf oxygen consumption (V o 2) is known (in an adult usually around 200–250 ml/min) then blood flow is calculated by the simple equation: where Q = blood flow in l/min. Thus, in the above example, if the content difference is 50 ml/l and oxygen consumption is 250 ml/min then blood flow is 5 l/min.

WebThe formula used is based on the Fick principle which assumes that the rate of blood flow is correlated with oxygen consumption (in this case oxygen consumption is assumed based … WebAn old technique based on the Fick Principle can compute cardiac output (CO) indirectly from whole body oxygen consumption (VO 2), and the mixed venous (CvO 2) and arterial oxygen concentrations (CaO 2). Although this technique is seldom used to determine CO, it can be calculated by the following equation: CO = VO 2 /(CaO 2 − CvO 2)
