OPERATOR ACTION
FLUID OUT
“FLUID OUT, CHECK
INLET TUBING AND
FILTER. ADD MORE
FLUID.”
Out of fluid.
Bag clamps not fully
opened.
Bag not fully spiked.
Tubing in the Fluid out
sensor is not seated firmly
in the detector.
Tubing in the Fluid out
sensor is stretched or
tubing pulls away from the
sensor, due to vacuum in
line.
Clogged air vent filter.
Clogged coarse blood
filter.
Reservoir or recirculate
line is obstructed.
Detector electronics
defective
Stop pumping and
heating. Sound alarm
and display message.
Valve in the
recirculate position.
Press MUTE to silence the alarm.
If out of fluid, add additional fluid and press REPRIME.
If the Re-prime volume count does not count down from 100 to 0 ml: then
•
Check that bags are fully spiked and clamps are fully opened.
•
The reservoir chamber should be seated in the holder. Check that the
pump head tubing is not stretched and is seated firmly within the fluid
out sensor.
•
Check the fluid out sensor and make certain it is clean and there is
nothing obstructing contact with the sensor.
If the reservoir chamber stays empty during re-prime, the air vent filter may
be clogged. In this case, pierce the fluid bag(s) with bag spikes and fully
open clamps to allow air in the reservoir chamber to escape into fluid bag(s)
and allow fluid to fill the reservoir chamber.
High amounts of particulates in the blood will clog the coarse blood filter in
the reservoir chamber. Replace reservoir chamber or disposable every 4
hours of operation.
Replace the detector electronics or the daughter board.
