Medical Definition of Hydraulic conductivity
1. Ease of pressure filtration of a liquid through a membrane; specifically, Kf = η(Q/A) (dx/dP), where Kf = hydraulic conductivity, η = viscosity of the liquid being filtered, Q/A = volume of liquid filtered per unit time and unit area, and dx/dP = reciprocal of the pressure gradient through the membrane; solute concentrations should be identical on both sides of the membrane. Also applied more loosely to measurements on a total membrane of unknown area and thickness with unmeasured fluid viscosity (K = Q/dP). (05 Mar 2000)
