Technical Bulletin CLX #04 The Centrifuge Bowl Optic Sensor and Resolving Red Cell Pump Alarms October 2010
Purpose This bulletin is being issued to provide additional instructions about how to resolve Red Cell Pump alarms. This bulletin recommends several steps to supplement the THERAKOSTM CELLEXTM Photopheresis System Operator’s Manual, and the information displayed on the instrument screen during the alarm.
Learning to Use the Displayed Centrifuge Bowl Optic Sensor Value The main screen display shows a spinning centrifuge highlighted in pink during COLLECT. •
To display values: a. To display the volume of the bowl in milliliters, tap on the centrifuge bowl icon once.
b. Then, tap on the cycle number icon six times. This will cause the volume (ml) icon to change to a bowl optic sensor value. Note that the displayed centrifuge bowl optic sensor value is followed by a green triangle.
•
The default BOWL OPTIC THRESHOLD VALUE is 150. The displayed centrifuge bowl optic sensor value has an inverse relationship to the position of the plasma / erythrocyte interface in the centrifuge bowl. o When the interface is directly in line with the level of the red laser beam, the displayed centrifuge bowl optic sensor value is 150. o When the interface is higher than the level of the red laser beam, the displayed centrifuge bowl optic sensor value is lower than 150. o When the interface is lower than the red laser beam, the displayed centrifuge bowl optic sensor value is higher than 150. NOTE: During RED CELL PUMP ALARMS or while processing whole blood with abnormal plasma conditions, displayed bowl optic sensor values may not follow the pattern described above.

Laser Beam
Figure 1. Default BOWL OPTIC THRESHOLD VALUE is 150 and interface is established During COLLECT, after PURGING AIR, the plasma / erythrocyte interface is established. At this time the displayed centrifuge bowl optic sensor value should match the BOWL OPTIC THRESHOLD VALUE. Then, as additional whole blood is processed and the leukocyte fraction expands, the position of the plasma / erythrocyte interface fluctuates. •
During DRAWING, when the interface is slightly higher than the level of the red laser beam, the displayed centrifuge bowl optic sensor value is between 150 and 140. o
When the interface is slightly lower than the level of the red laser beam, the displayed centrifuge bowl optic sensor value is between 150 and 160.
•
During RETURNING in Single Needle Mode, the centrifuge bowl spins and packs the erythrocytes. The position of the interface becomes even lower in the bowl, so the displayed centrifuge bowl optic sensor value becomes considerably higher than 160.
•
During PAUSE in either Double Needle Mode or Single Needle Mode, the interface again packs and becomes lower than the level of the red laser beam. So again, the displayed centrifuge bowl optic sensor value is considerably higher than 160.

Technical Bulletin CLX #04 The Centrifuge Bowl Optic Sensor and Resolving Red Cell Pump Alarms October 2010
Resolving Red Cell Pump Alarms Constant communication between the bowl optic sensor and the red cell pump (#2) is required to maintain the plasma / erythrocyte interface at the correct position during DRAWING. When a red cell pump alarm occurs, the operator must press MUTE and then determine if the interface is too low or too high before proceeding to the corrective action. • •
If the plasma / erythrocyte interface is too high, please proceed to page 5 for corrective action instructions. If the plasma / erythrocyte interface is too low follow the corrective actions below.
RED CELL PUMPS ALARM: Plasma / Erythrocyte Interface Too Low CAUSE: Lipids and / or bilirubin are present and elevated in the plasma
Figure 4a. First Example: Interface Too Low
Figure 4b. Second Example: Interface Too Low
CORRECTIVE ACTION: 1. Press MUTE to silence the alarm. 2. Go to SETUP to lower the BOWL OPTIC THRESHOLD VALUE by 10 and save. 3. Press RESET. 4. Press START, and lower the COLLECT flow rate to 25mL / min or less. 5. Observe the position of the interface. The erythrocytes should return to the level of the laser. 6. If the displayed centrifuge bowl optic sensor value has reached 140 (the new BOWL OPTIC THRESHOLD VALUE), but the erythrocytes are still not at the level of the laser, lower the new BOWL OPTIC THRESHOLD VALUE again by 10. Repeat as necessary. 7. If the alarm continues, contact Therakos for assistance.

Figure 5a. Example: Interface too low, the BOWL OPTIC THRESHOLD VALUE changed from 150 to 140.
Figure 5b. Displayed centrifuge bowl optic value is at 140, but interface is still below laser.
Figure 5c. Correct interface position is achieved following additional BOWL OPTIC THRESHOLD VALUE adjustments.
RED CELL PUMPS ALARM: Plasma / Erythrocyte Interface Too High CAUTION: If the interface rises too high, leukocytes may be lost to the return bag before BUFFY COAT begins.
CAUSES: • Poor access and slow flow rates • High flow rates combined with abnormal erythrocyte morphology • Occlusion of the Red Cell Out Line due to trapped air, platelet aggregates, or a pinched line In the alarm state, the interface rises above the laser level and the displayed centrifuge bowl optic sensor value becomes significantly lower than 140.

Technical Bulletin CLX #04 The Centrifuge Bowl Optic Sensor and Resolving Red Cell Pump Alarms October 2010 Follow these corrective action steps: 1. Press MUTE to silence the alarm. 2. Press RESET and check the level of the interface in the bowl. It may be at, or slightly above, the laser. The displayed centrifuge bowl optic sensor value will be much lower than 140. Determine the WHOLE BLOOD PROCESSED value, and choose one of the following corrective action procedures:
Whole Blood Processed: less than 500mL
Whole Blood Processed: 5001000mL
Whole Blood Processed: greater than 1000mL

Technical Bulletin CLX #05 Managing System Pressure Alarms October 2010
Purpose This bulletin is being issued to supplement the instructions currently in the THERAKOSTM CELLEXTM Photopheresis System Operator's Manual and displayed on the instrument during the alarm. Instructions now vary depending upon when the alarm occurs during the treatment. These instructions are suggestions to help an operator react to System Pressure alarms. They do not guarantee that a successful treatment will ensue, and do not replace an operator’s clinical judgment.
System Pressure Alarms The system pressure sensor is located on the pump deck above the pump tubing organizer. The system pressure dome is attached to the collect line between the collect pump (#1) and the drive tube and centrifuge bowl. The role of the system pressure sensor is to monitor the pressure of the centrifuge bowl during COLLECT. If the sensor detects extreme pressures (+/- 465mmHg or +/- 9PSI) in the centrifuge bowl, it will automatically stop the centrifuge from spinning. Following a system pressure alarm, before treatment may resume, the instrument must re-purge the centrifuge bowl.
Figure 1. Location of the System Pressure Sensor
Possible Causes of System Pressure Alarms •
Air trapped in the centrifuge bowl during PURGING AIR
•
Air added to the centrifuge bowl after PURGING AIR
•
Platelet aggregates
•
Increased viscosity of the product exiting the centrifuge bowl during BUFFY COAT

Technical Bulletin CLX #05 Managing System Pressure Alarms October 2010
Re-purging the Centrifuge Bowl Re-purging the centrifuge bowl is accomplished by drawing approximately 100mL of whole blood from the patient and simultaneously expelling 100mL of volume from the centrifuge bowl. •
To minimize the extracorporeal volume of the patient, the instrument will begin by RETURNING volume of the return bag until it is approximately 50mL, then it will proceed to DRAWING / PURGING AIR.
•
Leukocyte enriched blood may be lost from the centrifuge bowl during the re-purging process.
•
The WHOLE BLOOD PROCESSED TARGET may be increased to re-harvest additional leukocytes following a system pressure alarm.
Managing a System Pressure Alarm The management of a system pressure alarm may differ depending on when it occurs during the treatment. Please review the following table for assistance in resolving this alarm. Whole Blood Processed Volume or Phase When System Pressure Alarm Occurs 250-280mL
Possible Cause of the Alarm
Corrective Action
Comments
a) Small amount of air trapped in centrifuge bowl usually from union of collect line with patient access.
DO NOT remove the system pressure dome.
A leukocyte enriched fraction has not yet been developed in the centrifuge bowl. You may increase the whole blood processed target by 100mL, but it is not necessary.
b) Small platelet aggregate lodged in centrifuge bowl or red blood cell line due to start and stop access at the onset of treatment.
™Trademark of Therakos, Inc.
1) MUTE 2) Check centrifuge bowl in / out lines for pinch points 3) RESET 4) START Follow the screen display prompts and check the access connection to ensure that no additional air is seeping into the collect line.
At the very beginning of COLLECT / DRAWING / PURGING AIR visually inspect the luerlock connection between the collect line and the patient access to ensure a tight connection. Check the centrifuge bowl and the photoactivation module at the end of the treatment. If large numbers of platelet aggregates are present, you may need to alter the anticoagulant on future treatments. Consult the physician about the dose of anticoagulant and / or the ratio of delivery. Page 2 of 4
Technical Bulletin CLX #05 Managing System Pressure Alarms October 2010 Whole Blood Processed Volume or Phase When System Pressure Alarm Occurs Greater than 500mL
Possible Cause of the Alarm
Corrective Action
Comments
a) Air that has entered the centrifuge bowl following PURGING AIR
DO NOT remove the system pressure dome.
Re-purging the centrifuge bowl will exchange leukocyte enriched blood in the centrifuge bowl with new whole blood from the patient. If possible, increase the WHOLE BLOOD PROCESSED TARGET as much as possible to harvest additional leukocytes.
b) Platelet aggregates
1) MUTE 2) Check centrifuge bowl in / out lines for pinch points 3) RESET 4) START Follow the screen display prompts and check the entire collect line pathway for leaks.
Just before BUFFY COAT
Increased viscosity of the product exiting the centrifuge bowl.
DO NOT remove the system pressure dome. 1) MUTE 2) Check centrifuge bowl in / out lines for pinch points 3) RESET 4) START Follow the screen display prompts and check the entire collect line pathway for leaks.
Consider changing the anticoagulant delivery ratio to 8:1. Re-purging the centrifuge bowl will exchange leukocyte enriched blood in the centrifuge bowl with new whole blood from the patient. If possible, increase the WHOLE BLOOD PROCESSED TARGET as much as possible to harvest additional leukocytes. If it is not possible to raise the WHOLE BLOOD PROCESSED TARGETS, PAUSE to add additional dwell time in the centrifuge bowl before proceeding to BUFFY COAT. NOTE: The red cell pump (#2) needs time to bring the interface down to the level of the laser before proceeding to BUFFY COAT. Consider changing the anticoagulant delivery ratio to 8:1.

Technical Bulletin CLX #05 Managing System Pressure Alarms October 2010 Whole Blood Processed Volume or Phase When System Pressure Alarm Occurs During BUFFY COAT
Possible Cause of the Alarm
Corrective Action
Comments
Increased viscosity of the product exiting the centrifuge bowl.
DO NOT remove the system pressure dome.
Use a moderate to slow flow rate (not greater than 25mL / min) during BUFFY COAT to help minimize the increased pressure in the centrifuge bowl.
Before following the screen display prompts:
Remember that BUFFY COAT has two parts:
1) Determine which part of BUFFY COAT has been interrupted.
1) Collection of Plasma, leukocytes, and a 3-4% hematocrit
2) Visually inspect treatment bag to confirm contents of bag.
2) PAUSE, ELUTRIATING, collection of additional buffy coat At the end of BUFFY COAT
3) Proceed directly to PHOTO-ACTIVATE by following instructions in the adjacent comment section. Alarm threshold met as the centrifuge begins to stop.
DO NOT remove the system pressure dome. 1) Confirm that both parts of BUFFY COAT are complete, and the centrifuge has stopped.
Re-purging the centrifuge bowl will expel any remaining buffy coat to the return bag. If BUFFY COAT is interrupted, and the majority of white blood cells are in the treatment bag, do not press START! Instead, select the following:
Note that the STOP button is not available. This is because the centrifuge bowl has already stopped.
2) MUTE and RESET to exit the alarm state. 3) Press START to advance to the PHOTOACTIVATE phase and begin EMPTYING BOWL.
NOTE: For future treatments, consider alternative types of access devices to ensure optimal flow during COLLECT.
