Arlene, your post stirred some memory cells and I'm recalling a couple of discussions from last fall concerning the crit-line. Quotes and links:
From a Dialysis nurse with 9 years experience:
"I work for FMC and LOVE the crit line. In the absence of a crit line, all any nurse needs is some friggin' common sense to know if they are pulling off too much/too little fluid!!!
What the hell is wrong with everyone's staff???!!?? Honestly I find this whole topic very disturbing!!!!!!!
There is NO REASON dry weight should be a continuing issue beyond a couple of weeks. I change at least three dry weights/week, minimum, based on crit line and response to treatment!!!!!
Find out if your unit has a crit line....if so, DEMAND you get to use it if you think you're dry weight's wrong. If it doesn't have one, start a petition to get one. Hell, PM me and I'll write it up for you and e-mail it! If you get enough people to sign it, they'll get one for you!!"
http://www.ihatedialysis.com/forum/index.php?topic=15981.msg280889#msg280889From a dialyzor at Home Dialysis Central:
"Has anyone here experienced the Critline? I have, and felt better than I ever had as the Critline found a whole .9 that my usual txs were not removing, and through working with the Uf, we removed it. I have wondered if there is any place for the Critline in daily or nocturnal txs, because eventhough fluid is being removed daily, it does not necessarily mean that all available fluid is being removed unless proper assessment is used."
