I know my prescription but I don't know what parameter numbers fit where in my prescription. My first cycler went bad, we got a new cycler. They changed my treatment from flow fraction to time and the time they calculated was wrong. My flow fraction was 0.45 and with blood at 450 ml/min. that comes out to 12.15 dialysate rate. In the 30 liter treatment, that's a bit less than 2.5 hours. I want to change my dialysis flow rate to 12 l/hr. and my maximum ultrafiltration rate to 1 l/hr. What parameter number is for dialysate flow rate and max ultrafiltration rate? The doctor asked the nurse to correct it, but I remember the setting we used for years before the old machine broke.
