Title: Big change in UF
Post by: -Lady Noir- on May 14, 2010, 02:43:33 PM

Okay, so Mikes UF is generally between 1000 and 300. Until last night, when for some reason it was -67!
His weight this morning doesn't suggest hes overloaded or anything.

Does anybody have an idea of why this happens?

When I get a quirky reading, I just let it go and watch for a trend.

Did he have a heavy sodium day?  Sometimes that will cause a negative UF.  Or maybe he was really active and sweated a lot? 

I agree, watch for a trend with this.  An occassional negative UF isn't alarming but continued negatives should be discussed with your neph.

I currently use two 1.5% bags, 4 fills, (1800 first fill, 1710 next 3, tidal setting 95%)  Total dwell (programmed) is 6 hours.  I average between 700 - 1000 uf per night.  Every now and then I'll get a total uf of 40..  Completely out of the norm.  next day, back to the normal average.

If I got two or three in a row, I'd worry.  As it stands, I just roll with it.

Sometimes I get a negative UF and it's because I didn't drain completely during one of the cycles. The machine adds all the fluid going in and subtracts it from the fluid coming out, which is usually more. If you retain some because of constipation or whatever reason, it will be reflected in the UF.

When this happens, I don't have time to do a manual drain before going to work (I get up at 5:30), so when I do a manual exchange later in the day (around 3:30 when I get home), I get much more than the 1500 that's usually left by the machine (sometimes 2500).

It's an occasional problem, so I don't worry about it.

AH, cheers guys! Makes more sense now that i've had time to think about it, and read your feedback of corse  ;)

Was probably all of the above, higher sodium, exersize, constipation etc.

Thanks again  :2thumbsup;

Use of manual drain on the morning will solve this UF problem.

I would get negative UF from constipation of fibrin.  Using heparin will clear up any fibrin that could plug the lines.
