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 10 ml increments)
Maximum rate internally adjustable to 1, 2, 3, or 4 l/h.
Pump volume accuracy: ±1 % (at P
di
> –500 mbar)
The UF rate/effective blood flow ratio is being monitored during the
treatment. If an incongruity occurs a warning will be displayed after
approx. 10 seconds.
