WebFick’s laws: a back to basics For now, we consider mass transport in a medium at rest and with no chem-ical reaction. The basic laws of di usion bear the name of Fick. Fick’s rst law relates the di usion ux J D (e.g. in mol/s/cm2) to a concentration gradient. J D= DrC (1) Be aware that this is a vectorial equation. Inspecting this equation ... WebThe Fick principle is a mathematical equation that calculates cardiac output by multiplying the difference between arterial and venous oxygen partial pressures by the blood flow through the vascular bed. In other words, it takes into account how much oxygen is being delivered to and removed from the tissues.
