I,m on dialysis.  I just discovered that my tech is not turning the blood pump (not sure of correct name) down to 200 (which is policy at my dialysis center).  She is leaving the blood pump at the rate I dialyze (350).  What is the purpose of the blood pump rate?
Blood pump rate has direct impact on the critical parameters of dialysis including toxin clearance, fluid removal, dialysis adequacy and blood pressure stability during dialysis. Hence you should discuss the thing with the treating nephrologist as there are pros and cons of high as well as low blood pump speed. It depends on the clinical situation and the need of the day.
