What This Guide Helps With
This guide addresses situations where the HeartStart MRx:
- Displays a “Self-Test Failed” or similar error immediately on power-up
- Fails to complete its internal diagnostic checks
- Shows warnings that prevent the device from becoming ready for patient use
Focus is on external, logical troubleshooting first, ensuring patient safety and proper escalation rather than performing internal board-level repairs.
Step-by-Step Troubleshooting
Verify Battery and Connections
- Ensure the battery is fully seated and correctly inserted.
- Check for any visible damage, corrosion, or debris on contacts.
- Reason: A poor battery connection can cause the device to fail self-tests.
Check Battery Charge and Type
- Confirm the battery is charged and the correct model for the MRx.
- Swap with a known good battery if available.
- Reason: A weak or incompatible battery can trigger failed self-tests.
Inspect Pads and Cables
- Make sure electrode pads are connected properly, not expired, and cables are undamaged.
- Disconnect and reconnect pads to test if the error clears.
- Reason: MRx self-tests check pad connectivity; faults here can prevent passing.
Power Cycle the Device
- Turn the MRx off, wait 10–15 seconds, then power on.
- Observe if the self-test error persists.
- Reason: Temporary glitches or startup errors can sometimes resolve with a power cycle.
Environmental Check
- Ensure the device is not excessively hot, cold, or humid.
- Confirm power outlet or charging station is stable (if plugged in).
- Reason: Extreme conditions or unstable power can interfere with self-tests.
Inspect for Visible Damage
- Look for cracks, loose panels, or signs of liquid ingress.
- Reason: Physical damage may affect internal circuits causing test failures.
If the Problem Persists
Common external causes have been ruled out.
- The device should be removed from service
- Labeled Out of Service
- Sent for bench evaluation or repair by qualified personnel
Knowing when to escalate is proper troubleshooting.
Clinical Use Tip
- Do not attempt on a patient: Never rely on an MRx that fails self-test for patient care.
- Use a backup device: Ensure patient care continues with another verified, functional defibrillator.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“MRx displays ‘Self-Test Failed’ immediately on power-up.”
Cause
What was observed during troubleshooting.
Example:
Battery and pad connections verified, power cycle attempted, no improvement; device still fails self-test.
Resolution
What action was taken.
Example:
Device removed from service, labeled Out of Service, sent for repair.
Helpful Details to Include
- Battery model and charge status
- Pad type and expiration date
- Any error codes displayed during self-test
- Environmental conditions at the time of failure
- Previous service or repair history
Final Thought
Patient safety must come first. Always rule out simple, external causes before assuming internal failure. Proper documentation ensures quick repair turnaround and maintains department readiness. Escalating devices that fail self-tests is part of safe, logical troubleshooting.
That is successful troubleshooting.
