WebPHYSICAL PRINCIPLES OF HEMODIALYSIS. Hemodialysis alters the composition of blood by exposing it indirectly to a contrived solution, the dialysate, across a semipermeable membrane. Solute and fluid exchange occurs by diffusion or convection, and the magnitude of the exchange is predicated on physical characteristics of the solute and ... WebThe MCO dialyzers, which are used in HD-mode, achieve convective transport by internal convection, by varying the pressure gradient over the dialysis membrane to create a very high amount of backfiltration (approximately 7.6 L with Q b 300 mL/min, and 12.7 L with Q b 400 mL/min). 9 This internal convection thus gives a moderate convection volume … cry unit tallaght
