Hemodialysis diffusion

Web19 okt. 2016 · Hemodialysis (HD) is a relatively safe purification technique, which partly replaces renal function. Excess moisture and metabolic wastes were removed by HD, and in the meantime, calcium ion, bicarbonate ion, and other substances can be supplied. The core element is Ultrafiltration membrane [ 1 ]. WebWhat is diffusion in dialysis? The formal definition of diffusion in dialysis is movement of solutes as a result of random molecular motions across a semipermeable membrane …

The principle of hemodialysis is the same as other methods of dialysis; it involves diffusion of solutes across a semipermeable membrane. Hemodialysis utilizes counter current flow, where the dialysate is flowing in the opposite direction to blood flow in the extracorporeal circuit. Counter-current flow maintains the concentration gradient across the membrane at a maximum and increases the efficiency of the dialysis.
