Dialysate and dialysis principles

[enoi]

Compare the potassium found in the dialysate and that found in blood work.

The level of potassium in the patient blood work is 4.2 and the physician ordered a 3k 2.5 ca bath. why the patient is in this bath?

What I have been taught is that you want the potassium between the dialysate and the patient to equal around 7. Since the patient's level is 4.2, you'd go with a 3 for K level in the dialysate. If theirs was a 5, you'd go with a 2 and so on.

As far as calcium goes, there are multiple factors that go into this.

Yes, but you wouldn't go less than a 2K bath, not for more than an hour at least. Our calcium protocol is fairly simple, don't have the numbers in front of me but if CorCaY use a 2Ca bath. We go by the corrected calcium, Serum Calcium+((4-Albumin)*.8), but that's not the case everywhere. Docs don't usually get very concerned about the calcium bath used.

Our calcium protocol:

Corrected Calcium =

Corrected Calcium 8.7-10.7 use 2.5 Ca bath

Corrected Calcium => 10.8 use 2.0 Ca bath

I have only worked in 1 facility so I don't know how universal this is.
