Sorry Wildeymon,
Can't agree, never could! even if polite is my middle name
. The balance flow is exactly that(what goes in comes out)
ergo the fluid provided at one side balances the other, no matter how hard P03 runs it can't remove any more than is put in from the clean side.
The only way to increase the volume removed on the effluent side is to created a deficit in volume into the balance flow on this side, therefore the UF pump bypasses what returns to the balance flow, hence the increase in TMP, hence the fluid drag across the membrane of the dialyser!
the UF pump rotates instead of pumping as such so;
to remove 20L = say 2 L fluid loss we have 22L in 4 hours
this equates to 5500ml/h or 91.66mls/min
the volume of a UF pump is around 1ml so we have 90 ish rotations/min
or 9 rotations every 6 seconds, I would imagine this only shows as 1 illumination of the pump on the diagnostic flow diagram.
But I happily stand to be corrected
Peas owt
