What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting situations where the Vantive PrisMax CRRT system reports a pump module failure. Symptoms may include audible alarms, treatment interruption, or error messages indicating pump malfunction. Most issues are related to external factors such as improper cassette installation, obstructions, or misaligned connections before considering internal pump failure.
Step-by-Step Troubleshooting
Ensure Patient Safety
- Confirm that the patient is safely transitioned to another CRRT device if therapy must continue.
- Never troubleshoot a pump module while the patient is actively connected.
Check Power Source and Connections
- Verify AC power or battery status.
- Ensure the device is plugged into a known working outlet.
- Inspect power cables for damage.
Inspect Pump Cassette and Tubing
- Open the pump module compartment and check the cassette is seated correctly.
- Ensure all tubing lines are free of kinks, clots, or air.
- Confirm that tubing connections match the intended setup per manufacturer guidelines.
Reset the Pump Module
- Power cycle the device following standard shutdown/startup procedures.
- Observe if the pump error persists upon reboot.
Examine the Pump Mechanism
- Look for visible obstructions or residue in the pump rollers or chamber.
- Ensure the cassette locks and roller mechanisms move freely.
Check Device Software and Error Logs
- Review displayed error codes and log details to confirm pump failure.
- Record error codes for potential vendor support if escalation is needed.
If the Problem Persists
All external and user-level issues have been ruled out. The pump module may have an internal mechanical or electronic failure.
- Remove the device from service.
- Label as Out of Service.
- Send for manufacturer repair or internal bench evaluation.
Stopping here is proper troubleshooting to avoid patient risk or further damage.
Clinical Use Tip
- Always ensure therapy continuity by having a backup CRRT device ready.
- Do not attempt internal repairs on the pump module; these should only be performed by qualified service personnel.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
User reported the PrisMax alarmed and displayed a “Pump Module Failure” message during therapy.
Cause
What was observed during troubleshooting.
Example:
Clinical Engineering observed correct cassette installation and tubing, confirmed power and connections, but pump error persisted, indicating internal module failure.
Resolution
What action was taken.
Example:
Device removed from service, labeled Out of Service, and sent for manufacturer repair. Backup CRRT initiated for patient therapy continuity.
Helpful Details to Include
- Power source verified and functional
- Cassette correctly installed
- Tubing free of obstructions
- Pump compartment visually inspected
- Error code logged: [record specific code]
- Device labeled and removed from service
Final Thought
Patient safety and proper escalation are paramount. Logical, stepwise troubleshooting ensures that external causes are ruled out before internal failure is assumed. Thorough documentation using the CCR method provides a clear record for repairs and supports ongoing patient care.
That is successful troubleshooting.
