Compliance is checked under the following test conditions for typical peristaltic pumps.
– Apply a pump segment to the HAEMODIALYSIS EQUIPMENT and let it run for at least 30 min.
– Apply a fluid (e.g. water) with a temperature of 37 °C in the EXTRACORPOREAL CIRCUIT.
– Set the blood flow of the HAEMODIALYSIS EQUIPMENT to 400 ml/min or – if not possible - to
the highest possible blood flow.
– Set the ARTERIAL PRESSURE to -200 mmHg.
– Measure the blood flow.
The values of the measured blood flow shall be within the tolerances specified by the
MANUFACTURER in the instructions for use.
NOTE 2 Pump segment fatigue can reduce the blood flow rate.
NOTE 3 The blood flow rate in peristaltic pumps can be affected by negative input pressures
