NxStage System One - alarm "24"

Hi everyone. It’s me again - after another long break…

I have a issue with my recent txs on the System One and I am looking for some advice. Recently, I have been getting the “24” alarm during my tx. According to the manual, the “24” means that the arterial line is not getting enough pressure to run at the appointed speed (I run with a BFR of 400).

I haven’t had any problems with my fistula for a very long time now, and my getting the “24” alarm has me thinking about what could be the culprit.

My nurse says that it means my access is having problems and has scheduled an arteriogram for me. She is positive that there is a problem with my fistula that is just starting to brew and she wants to catch it before it gets worse.

I really don’t want to get an arteriogram unless I absolutely need it. I think it will put an undue amount of stress in my fistula.

The thing with the “24” alarm for me, is that I don’t get it on every tx, and I can make it go away for a while if I just adjust the “layout” of the tubing. I use buttonholes, so I don’t imagine it is the placement of the catheter.

Has anyone else dealt with a fairly regular “24” alarm?

Does it sound like I need to get an arteriogram to stop the progression of something bad that may be happening to/in my fistula?

Yes, I have dealt with those 24s and the problem on my end was that I had the arterial line pushed, and bent/kinked by my blanket or the needles itself has moved a bit and is hitting the vessel walls. All I would do is check the lines and move the arterial needle a bit…wiggle it a bit and the 24 would stops…

I asked patient who is on NxStage if he gets the #24. He said yes, often- just a kinked line. The alarm clears immediately after he straightens line. Did you ask your nurse why she thinks it’s an access problem vs a kinked line? Have your pressures changed? Does the way you tape your lines or leaning arm against chair cause them to kink?
