Dialysis fl uid preparation
Temperature:
Temperature alarm ( fi xed) 40 °C (±0.5 °C)
Overheat protection: The heater can only be on if there is a
fl ow through the heater. The fl ow is
detected by a fl ow switch.
Conductivity:
Alarm limits: ±5 % of the calculated conductivity set
value
Ultra fi ltration supervision
TMP:
TMP is de fi ned as the difference, P
b out
-
P
d out
, where P
b out
is the venous pressure
and P
d out
is the pressure measured in the
dialysis fl uid, where it enters the machine
after the dialyzer.
Alarm limits: -100 to 500 mmHg
Accuracy: ±500 ( ±10 mmHg or ±5 %, whichever is
largest )
Blood leakage detection
Detection method: Infrared light detector.
Sensitivity: Alarm will be given for ≥ 0.3 ml blood,
haematocrit 32%, per minute at 700
ml/min dialysis fl uid fl ow. Time delay
for alarm, maximum 5 seconds (diffusion
mode).
pH-meter
Measuring range: 1 - 9.9 pH, measured in the dialysis fl uid
before dialyzer.
Accuracy: ±0.2 pH
Alarm limits: 5.0 to 9.0 pH
