What This Guide Helps With

This guide assists Clinical Engineering in troubleshooting occlusion or line blockage alarms on a Fresenius Kabi Agilia infusion pump. These alarms occur when the pump detects high pressure in the infusion line, often caused by kinks, blockages, or improper setup rather than internal pump failure. The focus is on simple external checks first to ensure safe patient care.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• Stop the infusion and move the patient to another pump if necessary.
• Do not troubleshoot while the line is connected to an active patient.

Inspect the Infusion Line

• Check the tubing for kinks, bends, or compression.
• Ensure clamps are open and lines are not trapped under rails or bedding.

Check Syringe or Bag Position

• Confirm that the syringe or infusion bag is seated correctly.
• Misalignment can trigger occlusion alarms.

Verify Connections

• Ensure the catheter, extension sets, and pump tubing are fully connected.
• Loose or partially connected lines can cause pressure errors.

Examine the Filter or Luer Lock

• Some lines have inline filters or connectors that can block flow if obstructed.
• Replace filters if visibly blocked.

Check for Viscous or Particulate Solutions

• Highly viscous fluids may trigger alarms.
• Consider adjusting flow rate or using a larger gauge line if appropriate (per protocol).

Restart Pump

• Power cycle the pump to clear transient error messages.
• Confirm that alarms do not recur after reconnection with corrected setup.

If the Problem Persists

External causes have been ruled out (tubing, positioning, connections). The pump may have internal pressure sensor issues or mechanical blockages.

• Remove the pump from service.
• Label as “Out of Service.”
• Send to Fresenius Kabi service or internal bench evaluation.

Stopping here prevents risk to patients and avoids unnecessary internal damage.

Clinical Use Tip

• Always troubleshoot occlusion alarms off the patient first.
• Keep a backup infusion pump ready.
• Document any adjustments to avoid delays in therapy.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
“Pump keeps alarming for occlusion despite correct flow setup.”

Cause

What was observed during troubleshooting.

Example:
“Observed tubing kink under mattress; inline filter partially blocked.”

Resolution

What action was taken.

Example:
“Straightened tubing, replaced filter, and restarted pump. Alarm cleared, pump returned to service.”

Helpful Details to Include

• Outlet tested: Ensure power source stable.
• Tubing checked: Kinks, clamps, and connection points.
• Alarm type: Occlusion detected, pressure threshold exceeded.
• Flow rate: Normal for the therapy prescribed.
• Final device status: Pump returned to service or removed if unresolved.

Final Thought

Effective troubleshooting balances patient safety with methodical problem-solving. Always resolve simple, external causes before escalating to repair, and document every step. Proper CCR documentation preserves the chain of events and ensures safe continuity of care.

That is successful troubleshooting.
