CENTRIFUGE PRESSURE HIGH!
Alarm LED is red. Pumps and centrifuge stop.
To override the alarm for 60 seconds during Rinseback mode, press
CONTINUE
. This restarts the pumps.
This alarm occurs when the centrifuge pressure sensor measures pressure
above the specified limit.
.
CENTRIFUGE PRESSURE HIGH! Check
disposables for twisting.
CONTINUE
Probable Cause
Action
Blockage in inlet or RBC lines
Check for kinks or air in the inlet line and RBC line. Check for clamps on either line. Check for clots in the
return needle.
Twisted or pinched lines in the centrifuge
Ensure the channel and multi-lumen tubing are installed correctly.
Note:
If the alarm occurs during Prime mode, reseat the centrifuge sensor tubing and reprime the
disposable tubing set. To re-prime, press
CHANGE MODE
, then press
2
to select “Prime.”
Single-Needle TPE procedures:
The instantaneous inlet
pump flow rate is too high.
Note:
The occurrence of this alarm varies
with the patient’s Hct. The higher the patient’s
Hct, the lower the inlet pump flow speed at
which this alarm occurs
Lower the average inlet pump flow rate.
RBC line valve is closed
Open the RBC line valve.
Inlet pump flow rate is too high for the current Run mode
Reduce the inlet pump flow rate.
If power fails while centrifuge is spinning, pressure builds
up because the centrifuge coasts to a stop
Refer to the alarm, “RETURN PRESSURE HIGH! Check return line and needle.” on page 12-55, and perform the
action prescribed for the probable cause, “Buildup of pressure in the system caused by an alarm condition, or
operator action caused the centrifuge to stop.”
