Centrifuge Pressure High - Gambro Cobe Spectra Essentials Manual

CENTRIFUGE PRESSURE HIGH!

CENTRIFUGE PRESSURE HIGH! Check
disposables for twisting.
Alarm LED is red. Pumps and centrifuge stop.
Probable Cause
Blockage in inlet or RBC lines
Twisted or pinched lines in the centrifuge
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
RBC line valve is closed
Inlet pump flow rate is too high for the current Run mode
If power fails while centrifuge is spinning, pressure builds
up because the centrifuge coasts to a stop

CONTINUE
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.
Ensure the channel and multi-lumen tubing are installed correctly.
Lower the average inlet pump flow rate.
Open the RBC line valve.
Reduce the inlet pump flow rate.
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."
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.

Action
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."
