Proportioning of concentrates
The proportioning of concentrate is done through conductivity
control. The concentrates are pumped into the system with one/two
volumetrically supervised pumps. No minimum feeding pressure is
necessary, the fl uid is sucked in. Maximum feeding pressure, 150 kPa.

value
Ultrafiltration control
Note
•
Besides the ultra fi ltration, patient weight change during
treatment is also affected by other factors. These include
factors such as fl uid intake, food intake, perspiration, drug
administration, infusion priming and rinse-back volumes
amongst others. In addition, precise pre- and post-treatment
weight is critical for adequate assessment of the ultra fi ltration
during the treatment. If these measurements are not accurate
a discrepancy between the ultra fi ltration achieved during the
treatment and the changes in body weight will occur.
Note
Volume control Direct electromagnetic measurement of
dialysis fl uid fl ow, before and after the
dialyzer.
