Meaning of Fick principle | Babel Free

Definitions

A principle used in physiology and medicine, originally applied to measure cardiac output, stating that the total uptake (or release) of a substance by an organ is equal to the product of the blood flow through the organ and the arteriovenous concentration difference of the substance.

Examples

“The rate of blood flow in the peripheral and pulmonic vessels and the approximate size of existing shunts can be calculated by application of the Fick principle. […] It may be of interest to explain in some detail the Fick principle as employed in calculation of cardiac output, pulmonic blood flow and blood flow in shunts.”
