Dialyzer pressure
PDI
Dialysate inlet pressure
PV
Venous pressure
During therapy and reinfusion phase, 10 sec after start of blood
pump or plasma pump, and after change of the blood flow, or
after the manual level regulation of the venous or PBE chamber,
respectively, the lower and upper PV limits are automatically
adjusted. The
momentary acquired venous pressure (PV Ref)
serves as mean value for the calculation of the alarm window.
Lower limit:
PV min = (PV Ref – MinW) mmHg when PV Ref > MinW
PV min = 0 mmHg
when 5
PV Ref
MinW
PV min = -10 mmHg
when PV Ref < 5
MinW = Minimum PV window (default value = 20 mmHg)
Upper limit:
PV max = (PV Ref + MaxW) mmHg
MaxW = Maximum PV window (default value = 40 mmHg)
