Something that should be have been done is to have a baseline of what his fistula flow rate was when he first started dialysis. They could then do a test now to see if the flow rate has dropped or not. This test can help determine if it is just a couple bad runs or if the fistula is developing problems without the unnecessary procedure of having to have a fistulagram.With NxStage it would be very important to have a good fistula due to the NxStage machine having a very low dialysate flow rate compared to incenter machines.
I hope that extra day is just what Rob needs to get rid of that nausea Will this be a permanent thing or just temporary until he can start getting good clearances again? Sending good thoughts and prayers your way
