Staff checks condo of their dialysate before hooking up patient. What should be acceptable range?

I can only comment on the Fresenius machines but there is a range + or - 0.5 mS of TCD. That limit can be tighter if you wish. Personnaly if the condo. is + or - 0.2 mS I want to know about and have the machine checked.

I should be more specific. Staff brings the machine up in conductivity and then checks the machine with a Myron L or pHeonix meter. I know the machine's alarm will wrap around the TCD, but what's an acceptable range they can get when they check with the Myron L or pHeonix meter? At what point do they notify technical there's a problem?

A. +,- .5mS between the TCD and and the machine conductivity display.

B. +,- .5 mS between the machine conductivity display and the pHoenix meter.

Any reading that falls outside of the 2 parameters we report to the technical staff.
some units, the parameters are even lower

Our expected conductivity is 14.0 mS, this is how it it worded in our policy....

The dialysis machine can be used if:

The reading on the hand-held meter AND the dialysis machine display are between 13.5 and 14.5 mS, AND the two readings are within +/- 0.5 mS of each other.

If the reading is not within these parameters, the machine must be removed from service for repair.

I looked our policy up, so I was sure I was posting correct information. It says the conductivity must be between 13.3 and 14.3. If it is not, staff is supposed to check with another meter. If it is still out of range, the machine is supposed to be pulled.

Technically, I prefer some of above policies over ours. Our TCD for 1K is 13.5, which makes it kind of tight on the low end and too loose on the high end.

We tried to keep it simple.
