Has anyone using NxStage on SDD with a fistula experiencing higher than normal Venous Pressures for them? The last two weeks my venous pressures have been approx 50 points higher than normal.
Within 15 Mins of Tx Venous Pressures = 250-270’s. Normal would be 220’s, 230’s.
I am unable to go to a 400 blood flow until late in the tx due to the pressures.
After the UF Zeros when I reach my fluid goal, I up the Dialysate Flow Rate to maintain the flow fraction at 31.
A few minutes later, the Venous pressures will drop dramatically to normal numbers.
I received a new shipment of supplies from NxStage and decided to try a different Cartridge Lot # and behold… All pressures are normal from start to finsh. No Problems at all. I used the new cartridges for three days in a row and pressures are normal as can be.
I then decided to try one of the older cartridge lots for the heck of it and behold…High pressures again…
The Cartridge Lot #'s with the Higher pressures are: ( these have higher v pressures )
Lot # 8097701
Lot # 8107702
The new shipment cartridge Lot #'s are: ( these are good )
Lot # 8117702
Lot # 8117707
I notified NxStage Tech Support, sent them my Log Files, Asked if anyone else is reporting this issue and they state No… You are the first.
I will be going in this week to have my fistula checked just in case.
If anyone else is noticing Higher Venous Pressures with a fistual using NxStage? please post a message or email me at email@example.com
Thanks Much and Happy Holidays to all.
