Found this.. might be helpful.. "SLEDD techniques combine the advantages of CRRT and Intermittent Hemodialysis (IHD) by using conventional hemodialysis machines with blood flow rated (BFR) between 50-200 and dialysate flow rates (DSF) of 200-400. Dialysis time varies anywhere from 6 to 12 hours or can be done continuously. The possible variations and adaptations of blood flow, hemofiltration rate and duration of dialysis time as a function of needs of the patient are practically unlimited, which makes SLEDD applicable to the critically ill patient. " from "Slow, Low, Efficient, Daily Dialysis (SLEDD) in the Critically Ill Patient" By Pat Isaacs, MSN, CS, CNN, NP
None that I know of. The minimal dialysate flow on a conventional machine is set by the manufacturer. You would have to contact them to determine if there is an adjustment that could be made
