11.1.11 Dialysate Circuit and Safety Systems
Blood leak detector Response threshold
≤
0.5 ml blood loss per minute into the dialysate at
a hematocrit of 0.25.
(flow rate 100 ml/min to 1000 ml/min)
Transmembrane pressure Display range: –100 to 400 mmHg
Resolution: 5 mmHg
Definition:
Ultrafiltration Selectable UF rate: 0 ml/h to 4000 ml/h (in increments of 10 ml)
Maximum rate internally adjustable to 1, 2, 3, or 4 l/h.
Pump volume accuracy: ±1 % (for P
di
> –500 mbar)
The UF rate/effective blood flow ratio is being monitored during the
treatment. If a discrepancy occurs a warning will be displayed after
approx. 10 seconds.

= blood pressure on the outlet side of the dialyzer
P

= dialysate pressure on the inlet side of the dialyzer
P

= dialysate pressure on the outlet side of the dialyzer
Offset = Correction of flow-dependent pressure drops
