What This Guide Helps With
This guide helps troubleshoot the Cassette Dislodged alarm on the Cardinal Health Kangaroo OMNI feeding pump. This alarm may occur when the cassette is not fully seated, the feeding set cassette is damaged or misaligned, contamination prevents proper loading, or the pump cannot reliably detect the cassette.
A Cassette Dislodged alarm can interrupt feeding or flushing and should be treated as a delivery interruption until the setup is verified safe.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- If the Kangaroo OMNI is connected to a patient and the cassette alarm prevents feeding or flushing, do not continue relying on that pump.
- Stop the feeding or flushing process according to clinical policy.
- Ensure the patient’s nutrition or hydration plan is maintained with another verified pump if needed.
- Do not repeatedly clear the alarm on an active patient setup without clinical awareness.
Verify the Reported Alarm and Behavior
- Confirm the pump display shows Cassette Dislodged.
- Ask clinical staff when the alarm occurred.
- Check whether it appeared immediately after cassette loading, at startup, when feeding was started, during feeding or flushing, or after the pump was moved or handled.
- Observe whether the cassette appears loose, tilted, partially seated, or difficult to lock into position.
Remove the Pump From Active Patient Use Before Reloading
- If connected to the patient, pause therapy and follow facility procedure before manipulating the feeding set.
- Do not reload, prime, or troubleshoot the cassette while connected to the patient unless clinical staff confirms it is safe.
- Use a backup feeding pump if therapy must continue while troubleshooting is performed.
Reload the Cassette
- Open the cassette loading area and remove the cassette.
- Reload the cassette fully into the Kangaroo OMNI pump.
- Confirm the cassette sits flat, properly aligned, and fully seated.
- Press Continue after reloading.
- Verify whether the Cassette Dislodged alarm clears.
Check for Simple Loading Obstructions
- Inspect the cassette area for visible obstruction, spilled enteral formula, residue, moisture, or contamination.
- Wipe away external contamination using approved cleaning practices.
- Allow the cassette area to dry before reloading the feeding set.
- Reload the cassette and confirm it seats smoothly without resistance or misalignment.
Inspect the Feeding Set Cassette
- Remove the feeding set and inspect the cassette for cracks, warping, bent plastic, loose components, formula buildup, or other visible damage.
- Check whether tubing near the cassette is pulled tight or improperly routed.
- Confirm the feeding set is compatible with the Kangaroo OMNI pump.
- Do not force a damaged or distorted cassette into the pump.
Replace the Kangaroo OMNI Feeding Set
- If the alarm continues after reloading, replace the Kangaroo OMNI feeding set with a new compatible set.
- Load the new cassette correctly and press Continue.
- Confirm whether the new feeding set is recognized and the alarm clears.
- If the alarm clears with a new set, document the original feeding set as the likely cause.
Check for Pump-Specific Behavior
- If appropriate and safe, test the suspect pump with a known-good feeding set.
- If available, compare the removed feeding set on another Kangaroo OMNI pump using facility-approved procedures.
- Determine whether the issue follows the feeding set or stays with the pump.
- If the issue stays with the pump after a known-good feeding set is used, remove the pump from service.
Stop When Resolved
- If reloading the cassette or replacing the feeding set clears the alarm, verify normal pump operation before returning the pump to service.
- Confirm there are no repeated cassette alarms during setup, priming, or start of feeding.
- Document the corrective action and final pump status.
- Return the pump to service only after functional checks are acceptable.
If the Problem Persists
If the Cassette Dislodged alarm continues after proper cassette loading, inspection, cleaning of obvious external contamination, and replacement of the Kangaroo OMNI feeding set, external and common causes have been ruled out.
A persistent Cassette Dislodged alarm may indicate a pump-side cassette detection, loading mechanism, or internal sensing issue.
Remove the pump from service, power it off, label it Out of Service, and send it for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device first.
For cassette-loading alarms, do not repeatedly reload or prime the cassette on an active patient setup without clinical awareness. If feeding or flushing is interrupted, transfer therapy to another verified pump rather than continuing to clear the alarm.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Kangaroo OMNI feeding pump reported with Cassette Dislodged alarm. Staff stated cassette alarm occurred after loading feeding set and pump would not continue feeding."
Cause
What was observed during troubleshooting.
Example:
"Cassette was not fully seated in the pump. Alarm cleared after cassette was removed, reloaded, and accepted by the pump."
Resolution
What action was taken.
Example:
"Reloaded cassette, pressed Continue, verified Cassette Dislodged alarm cleared, and confirmed pump operated normally during setup. Device returned to service."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Cassette Dislodged alarms should be approached as real delivery interruptions until proven otherwise. Start with patient safety, confirm the alarm, reload the cassette correctly, inspect the feeding set, and replace the set before suspecting pump failure. If the alarm remains after basic external checks, remove the pump from service and escalate appropriately. Clear CCR documentation supports safe return to service or repair follow-up.
That is successful troubleshooting.
