What This Guide Helps With
This guide helps troubleshoot the Kangaroo OMNI Feed Error alarm when the pump detects a feeding delivery problem. Common causes include an empty feed bag, air bubbles, foam, clogs, kinks, tubing restrictions, cassette seating issues, or contamination near the occlusion sensor region.
A Feed Error can interrupt nutrition delivery and may stop the pump from feeding until the fluid path is corrected and the feeding set is safely primed.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- If the Kangaroo OMNI is actively delivering feeding or flush to a patient, notify clinical staff before troubleshooting.
- Do not prime the feeding set while connected to the patient.
- Disconnect the patient from the feeding set before priming or clearing air from the line.
- If feeding must continue and the alarm cannot be quickly corrected, transfer the patient to a known-good pump.
Expected outcome: Patient feeding is managed safely while the alarm condition is checked.
Why it matters: Priming while connected to the patient may deliver unintended fluid or air.
Verify the Reported Feed Error and Behavior
- Confirm the pump display shows Feed Error.
- Ask staff whether the alarm occurred during active feeding, shortly after starting the feed, after the bag ran low, after tubing was moved, intermittently during low-rate feeding, or only with one feeding set or cassette.
- Observe whether the pump stops feeding, continues alarming after reset, or alarms again after priming.
Expected outcome: The Feed Error is confirmed and the timing is understood.
Why it matters: Feed Error usually points to a delivery-path issue between the feed bag and pump, not necessarily a failed pump.
Check Whether the Feed Bag Is Empty
- Inspect the feed bag for remaining formula or fluid.
- If the bag is empty, have clinical staff refill or replace the feeding solution as appropriate.
- Press Continue, then prime the set before restarting the feed.
Expected outcome: The pump resumes feeding without the Feed Error returning.
Why it matters: An empty bag is the simplest and most common real-world cause of this alarm.
Check for Air Bubbles in the Tubing
- Inspect the tubing between the feed bag and the pump cassette.
- Look for visible air gaps, large bubbles, or sections of tubing that are not fully filled with formula.
- Disconnect the patient before priming.
- Prime the feeding set to move air through the tubing until the line is properly filled.
Expected outcome: Air is cleared from the feeding path and the alarm does not return.
Why it matters: The pump may interpret air in the feeding path as an interruption in fluid delivery.
Check for Kinks, Clamps, or Tubing Restrictions
- Trace the tubing from the feed bag to the pump.
- Confirm the tubing is not kinked, pinched, clamped, twisted, stretched, or compressed by bed rails, poles, or other equipment.
- Straighten the tubing and verify fluid can move through the set.
Expected outcome: The feeding path is open and unrestricted.
Why it matters: A restriction between the bag and pump can trigger a Feed Error because the pump cannot pull formula consistently.
Check for Clogs or Thick Formula Buildup
- Inspect the tubing for thickened formula, sediment, dried feeding solution, or visible blockage.
- If a clog is suspected, prime the line after disconnecting the patient.
- Replace the feeding set if the blockage cannot be cleared safely.
Expected outcome: Formula flows through the tubing without restriction.
Why it matters: A partial clog may allow some flow but still cause intermittent Feed Error alarms.
Check for Excessive Foam
- Inspect the feed bag and tubing for excessive foam.
- If foam is present, allow the formula to settle if clinically appropriate, and re-prime the tubing before restarting.
- Verify the bag is hung correctly and the set is loaded without agitation or trapped air.
Expected outcome: Foam is reduced and the pump can detect fluid movement correctly.
Why it matters: Foam can interfere with normal feeding detection and may be interpreted like air in the line.
Reload the Feeding Set Cassette
- Pause the pump and remove the cassette.
- Inspect the cassette for improper seating, fluid residue, damage, or formula contamination.
- Reload the cassette fully and correctly into the pump.
- Restart the feeding process according to facility procedure.
Expected outcome: The cassette seats correctly and the Feed Error clears.
Why it matters: A misloaded cassette can prevent proper pump operation even when the bag and tubing appear normal.
Clean and Dry the Occlusion Sensor Region
- With the cassette removed, inspect the occlusion sensor region for formula residue, moisture, dried feeding solution, or debris.
- Clean and dry the area according to facility-approved cleaning practice.
- Reload the cassette and test again.
Expected outcome: The pump no longer falsely detects a feed-path issue.
Why it matters: Contamination or moisture near the sensing area can cause false or repeated alarm detection.
Replace the Feeding Set
- If the bag contains formula, tubing is not kinked, air has been primed out, and the cassette area is clean, replace the feeding set.
- Use a new compatible Kangaroo OMNI feeding set.
- Prime the new set before reconnecting to patient use.
Expected outcome: The alarm clears with a new set.
Why it matters: The issue may be caused by a defective cassette, tubing restriction, or set-related sensing problem.
Test With a Different Pump if Available
- If feeding must continue, move the patient to a known-good pump.
- If the alarm follows the feeding set, suspect the set or fluid path.
- If the alarm remains only with the original pump after external causes are ruled out, suspect a pump-side sensing or mechanical issue.
Expected outcome: The problem is isolated to the feeding set, setup, or pump itself.
Why it matters: Swapping the pump helps distinguish accessory-related problems from device-related failure.
Recognize Alarm Detection Timing
- Feed Error detection may not happen immediately.
- At very low rates, such as 1 mL/hr, detection may take up to 40 minutes.
- At rates above 50 mL/hr, detection may occur within about 5 minutes.
Expected outcome: Testing expectations match the pump’s detection behavior.
Why it matters: A pump may appear normal briefly at low flow rates even when a feed-path problem still exists.
Stop When Resolved
- If the Feed Error clears after refilling the bag, removing air, correcting a kink, replacing the set, cleaning the sensor area, or reloading the cassette, verify normal operation before return to use.
- Confirm the pump runs without the Feed Error returning.
- Return the device to service only when feeding operation is stable and the alarm condition is corrected.
If the Problem Persists
If the Feed Error continues after checking the feed bag, tubing, air bubbles, foam, cassette loading, sensor cleanliness, and feeding set replacement, external and common causes have been ruled out.
A persistent Feed Error under known-good setup conditions may indicate a pump-side sensing, cassette interface, or internal delivery detection issue.
Remove the pump from service.
Label it Out of Service.
Send it for repair or bench evaluation.
Do not keep swapping clinical setups indefinitely once a pump-related failure is suspected.
Clinical Use Tip
Never troubleshoot on an active patient. Do not troubleshoot or prime the feeding set while connected to an active patient. Move the patient to a backup device first if nutrition delivery must continue and the Feed Error cannot be quickly resolved.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Kangaroo OMNI feeding pump reported with Feed Error alarm during feeding. Staff stated pump alarmed with formula still in the bag and feeding delivery stopped."
Cause
What was observed during troubleshooting.
Example:
"Found air bubbles and partial tubing restriction between feed bag and pump cassette. Feed Error cleared after tubing was corrected and feeding set was primed with patient disconnected."
Resolution
What action was taken.
Example:
"Removed air from feeding set, corrected tubing path, reloaded cassette, and verified pump operated without Feed Error returning. Device returned to service."

Final Thought
The Kangaroo OMNI Feed Error should be approached as a fluid-path alarm first. Check the bag, tubing, air, foam, cassette, and sensor area before suspecting the pump. Patient safety comes first, especially when priming or clearing the line. If the alarm continues after common external causes are corrected, remove the pump from service and document the findings clearly.
That is successful troubleshooting.
