5.11 Ratio of calcium flow to filtrate flow
The calcium flow rate is calculated by the system depending on the
filtrate flow (sum of the dialysate flow, substituate flow, net UF, citrate
flow, and calcium flow), the set calcium dose, and the concentration of
the calcium solution used, which is defined in the Setup menu of the
multiFiltrate. The calcium flow is limited by the control range of the
calcium pump.
Control range of the calcium pump: 10–100 ml/h
If the respective settings of the various flows and the required calcium
dose result in a calcium flow outside the pump control range, a warning
will be emitted.
The operator now has to adjust the waste volume appropriately by
modifying the dialysate and / or substituate flow or, if necessary, also
the calcium dose.
The UFR / BPR ratio will be displayed when
changing the parameters.
