WebEditor-In-Chief: C. Michael Gibson, M.S., M.D. Developed by Adolf Eugen Fick (1829 - 1901), the Fick principle was first devised as a technique for measuring cardiac output.However, its underlying principles may be applied in a variety of clinical situations. The essence of the Fick principle is that blood flow to an organ can be calculated using … WebJul 1, 2010 · Abstract. On the basis of an interesting case of a 40-year-old lady with an atrial septal defect, we describe a simple approach for complex shunt volume calculations based on the Fick principle using hemodynamic data obtained in the catheterization laboratory. Understanding Fick's principle allows determination of all relevant flows, flow ratio ...
