What This Guide Helps With
Error 314 indicates the downstream (DS) pressure sensor is reading high even when no tubing is installed. This prevents the pump from passing self-check and safely operating due to unreliable occlusion detection.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use immediately
- Transfer infusion to a backup pump if therapy is active
- Confirm patient care is not interrupted
Verify the Reported Error and Behavior
- Power on the pump and observe startup
- Confirm Error: 314 DS no-tube elevated is displayed
- Check if the error occurs during startup or with no tubing installed
- Determine if the issue is consistent or intermittent
Inspect Pump Channel for Obstruction or Contamination
- Open the pump door and inspect the tubing channel
- Look for dried fluid, debris, or residue
- Clean using approved methods if contamination is present
Check for Mechanical Obstruction or Misalignment
- Inspect pumping fingers and internal components
- Ensure nothing is restricting movement
- Verify components return to normal position when door is opened
- Look for visible damage or warping
Perform Power Cycle
- Turn the pump off
- Disconnect from AC power
- Wait 30–60 seconds
- Restart the pump
Test Without Tubing Installed
- Close the door with no tubing loaded
- Power on the pump
- Observe if the error is still present
Load Known-Good Tubing Set
- Install a new Baxter-approved IV set
- Ensure proper alignment and loading
- Verify normal operation without error
If the Problem Persists
If Error 314 continues after cleaning, inspection, and testing with no tubing and known-good tubing, external causes have been ruled out.
- Remove the device from service
- Label the device Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot a pump on an active patient. Always transition the patient to a backup infusion device before evaluating alarms or errors.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 314 DS no-tube elevated during startup; unable to initiate infusion."
Cause
What was observed during troubleshooting.
Example:
"Downstream pressure sensor reading high with no tubing present; no external obstruction or contamination found."
Resolution
What action was taken.
Example:
"Cleaned pump channel and verified proper operation. Error persisted; removed from service and sent for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Pressure sensor errors directly impact infusion safety and occlusion detection. Always rule out contamination and setup issues first, then escalate promptly when abnormal readings persist.
That is successful troubleshooting.
