WebApr 11, 2024 · In HD the ratio between dialysate flow (Q D) to blood flow (Q B) determines the duration of the diffusion process. In intermittent HD, it is common to use Q D higher than the Q B rate, thus, dialysis efficacy depends on Q B. The diffusion speed through the dialysis membrane is related to the molecule weight of the drug, surface area, and ... WebThe 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 ... WebJul 17, 2014 · Summary of diffusion with hemodialysis.

WebDialysis involves passing the patient’s blood against a semi-permeable membrane, with dialysis solution on the other side. At this stage, three processes can occur to remove unwanted waste products. Passive diffusion occurs when a high to low concentration gradient is present between the patient’s blood and dialysis solution (dialysate ... WebFeb 22, 2024 · Solute removal — In conventional hemodialysis, solutes are removed mostly by diffusion, which is the random movement of solute molecules down a concentration gradient. Such movement results from the thermal kinetic energy of the molecules; at the same temperature (and, therefore, energy), larger molecules move …
