What This Guide Helps With
Identifies external causes of power loss or battery failure, including outlet problems, battery depletion, loose connections, or AC adapter/cable faults.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm no patient is actively undergoing an EKG.
- Expected outcome: Patient safety maintained; device can be safely powered down.
Verify AC Power Connection
- Ensure the power cord is fully seated in both the device and wall outlet.
- Expected outcome: Device powers on; if not, continue troubleshooting.
Check the Wall Outlet
- Plug a known working device into the same outlet or use a portable outlet tester.
- Expected outcome: Confirm outlet provides power; if no power, address electrical supply.
Inspect the Power Cord and Adapter
- Look for visible damage, frays, or loose connectors.
- Swap with a known good cord if available.
- Expected outcome: Device receives power; eliminates cord as a cause.
Verify Battery Status
- Remove the battery (if hot-swappable) and check for proper seating or corrosion.
- Replace with a charged battery if needed.
- Expected outcome: Device powers on via battery; confirms battery functionality.
Test Device Power-On Behavior
- Attempt to power the device with AC and battery separately.
- Expected outcome: Device powers on normally; any failure here indicates internal issue.
If the Problem Persists
Common external causes have been ruled out. Device should be removed from service, labeled Out of Service, and sent for repair or bench evaluation. Recognizing when to stop avoids potential damage and ensures patient safety.
Clinical Use Tip
Never attempt power troubleshooting during an active patient scan. Move patients to a backup EKG machine before starting repairs.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Device failed to power on; screen remained blank."
Cause
What was observed during troubleshooting.
Example:
"Battery was fully discharged; AC cord was loose."
Resolution
What action was taken.
Example:
"Reconnected AC cord and installed a charged battery; device powered on successfully."
Helpful Details to Include (If Known)
- Battery voltage or charge level
- AC cord inspection notes
- Outlet testing results
- Device status after each test
Final Thought
Power and battery issues are usually external and easily testable. Logical, stepwise troubleshooting ensures patient safety and prevents unnecessary internal repair. Accurate documentation provides clear records for future reference.
That is successful troubleshooting.
