Fick's method

WebJul 7, 2014 · The Fick principle states that uptake or release of a substance by any organ is the product of the arteriovenous (A-V) concentration difference of the substance and the blood flow to that organ. The substance in this case is oxygen in blood, but it could be other types of indicators as well. WebThe Fick principle, as applied to cardiac output, relies on the recognition that the total uptake of oxygen by the peripheral tissues is equal to the product of the blood flow to the …
