Another form of dialysis with higher convection volumes is on-line hemodiafiltration (OL-HDF), which offers a superior clearance of uremic substances with a greater spectrum of molecular sizes. 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 …
