| fick's law of diffusion | The principle that a substance put into solution will tend to diffuse towards constant concentration throughout the solution. (09 Oct 1997) |

| Fick's laws of diffusion | The direction of movement of solutes by diffusion is always from a higher to a lower concentration and the diffusive flux JA of solute A across a plane at x is proportional to the concentration gradient of A at x; i.e., JA = -D(CA/x), the increase of concentration of solute A with time, CA/t, is directly proportional to the change in the concentration gradient, i.e., CA/t = D(fl2/x2).

| Fick method | In 1870 A. Fisk proposed that cardiac output can be calculated as the quotient of total body oxygen consumption divided by the difference in oxygen content of arterial blood and mixed venous blood. In the direct Fick method all variables are measured. The indirect Fick method employs a variety of means to avoid measuring mixed venous oxygen content. By extension, the Fick method may be used to measure cardiac output or organ blood flow with any indicator substance for which the rate of uptake or consumption, and the arterial and mixed venous concentrations, can be measured, provided the indicator does not enter or leave the system by any route not being measured. Synonym: Fick principle. (05 Mar 2000) |

| Fick's first l. of diffusion |
a substance will diffuse through an area at a rate which is dependent upon the difference in concentration of the substance at two given points.
