Measuring range: –50 mmHg to +750 mmHg
For haemoperfusion: –50 mmHg to +500 mmHg
Delivery rate: 10 ml/min to 500 ml/min
(MPS: 10 ml/min to 300 ml/min)
(Citrate anticoagulation: 10 ml/min to 200 ml/min)
(Paed. treatment: 10 ml/min to 100 ml/min)
Control accuracy: ±5%
Inner line diameter: 6.4 mm
System accuracy of the delivered blood volume: ±10% over the
complete duration of the treatment for typical treatment situations.
Warning
Reduced treatment effectiveness
If the arterial pressure before the blood pump reaches extreme negative
values, the blood flow may be reduced, which will affect the
effectiveness of the treatment.
Time-based standstill monitoring as a safety system against blood loss
through coagulation.
Operator stops the blood pump with the [STOP] key; immediate visual
alarm, acoustic alarm after 2 minutes.
Response threshold: drop of the fluid level, air bubbles, foam or
microfoam (blood / air mixture) over the entire blood flow range of
0 ml/min to 300 ml/min or 500 ml/min
Method: ultrasonic transmission
Pump type: syringe pump
Delivery rate: 0.1 ml/h to 25 ml/h
Resolution: 0.1 ml/h
Accuracy: ±5% for a delivery rate of 1 ml/h to 25 ml/h and a
measurement time of 2 hours up to a counterpressure of 1.2 bars
(calibrated for 30 ml Fresenius heparin syringes). With delivery rates
< 1.0 ml/h, the tolerance may exceed the specified ±5% accuracy.
Bolus administration: 0.5 ml to 5 ml in increments of 0.1 ml (the
maximum bolus amount to be injected is preset to 5 ml. This parameter
can be set to smaller volumes in the System parameters screen).
Measuring range: 0 to 5 drops / second
Pump type: roller pump
Delivery accuracy: pressure-dependent, ±10% (above typical pressure
range); for delivery rates < 6 ml/h, the deviation can be ±20%
Delivery rate: 10 to 600 ml/h (citrate / blood ratio: citrate concentration
per litre of delivered blood: 2–6 mmol/l)
