What This Guide Helps With
This guide addresses Error 241.4140 indicating low patient-side pressure sensor voltage, which can lead to inaccurate downstream pressure monitoring, missed occlusions, or interruption of infusion therapy.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Stop the infusion immediately
- Transfer therapy to a verified working pump
- Clamp tubing as needed to prevent unintended flow
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 241.4140 is displayed
- Observe whether the error occurs at startup or during infusion
- Check if infusion is prevented or stopped
- Note any additional pressure or occlusion alarms
Check Administration Set Compatibility and Installation
- Confirm use of a BD-approved Alaris administration set
- Open the pump door and reseat the set properly
- Ensure tubing is correctly aligned within the pump channel
Inspect Patient-Side Tubing for Occlusion or Restriction
- Trace tubing from pump to patient
- Check for kinks, tight bends, or closed clamps
- Inspect connectors and filters for blockage
Inspect Pump Channel for Contamination or Damage
- Open the pump door and visually inspect the channel
- Look for fluid intrusion or dried residue
- Check for debris or wear near sensor contact areas
Replace with a Known-Good Administration Set
- Install a new BD-compatible set
- Run the pump and observe if the error clears
Power Cycle the Pump Module
- Turn the module off
- Wait 10–15 seconds
- Power it back on and recheck for the error
Test Operation Off Patient
- Run a test infusion setup
- Monitor for stable operation without alarms
If the Problem Persists
If Error 241.4140 continues after all external checks:
- External causes such as administration set, tubing, and contamination have been ruled out
- The issue likely indicates internal failure of the patient-side pressure sensor or related circuitry
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot pressure-related errors on an active patient. Always transfer the patient to a backup infusion device before continuing diagnostics.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"BD Alaris pump displaying Error 241.4140, infusion stopped during use."
Cause
What was observed during troubleshooting.
Example:
"Error persisted after replacing administration set and verifying tubing; no external obstruction found."
Resolution
What action was taken.
Example:
"Removed pump from service and sent for repair due to suspected internal pressure sensor failure."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Patient-side pressure sensor errors directly affect infusion safety and occlusion detection. Always rule out external setup issues first, but escalate quickly once internal failure is suspected.
That is successful troubleshooting.
