Finite Volume Scheme for Double Convection-Diffusion Exchange of Solutes in Bicarbonate High-Flux Hollow-Fiber Dialyzer Therapy
Figure 4
Bicarbonate and carbon dioxide concentration gradients increased along the membrane axial distance at different time periods. (a) Depicted carbon dioxide maxima gradients shifting toward the membrane end and decreasing from their maxima. (b) Displayed bicarbonate gradients peaking at the same position inside the membrane. Maxima concentration gradients were achieved for both carbon dioxide and bicarbonate under an hour during the dialysis therapy.
