What This Guide Helps With
Depleted Battery alarm indicating critically low battery, risking sudden pump shutdown and interruption of infusion therapy.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- If infusion is active, immediately plug the pump into AC power or transfer therapy to another pump
- Confirm the patient continues receiving ordered therapy without interruption
2. Verify the Reported Alarm and Behavior
- Confirm the alarm message: “Depleted Battery! Plug into AC now!”
- Observe when the alarm occurs (startup or during infusion)
- Check if the pump is still operating or shutting down
- Look for any additional power-related warnings
3. Connect to AC Power (Immediate Action)
- Plug the pump into a known working AC outlet
- Ensure the power cord is securely connected
- Verify outlet functionality using another device if needed
- Confirm AC power indicator is present on the pump
4. Inspect Power Cord and Connections
- Check for damage, fraying, or loose connections
- Try a known-good power cord if available
- Ensure the cord is fully seated in the device
5. Confirm Battery Charging Behavior
- Observe for battery charging indicators or icons
- Allow the pump to remain plugged in for several minutes
- Verify the alarm clears and battery status improves
6. Isolate Battery vs Device Issue
- Try a different outlet
- Try a different power cord
- Monitor for intermittent loss of AC power
7. Stop When Resolved
- If the alarm clears and battery begins charging, return the pump to service
- Ensure adequate charge before unplugging for patient use
If the Problem Persists
If the alarm continues despite confirmed AC power:
- External power sources and connections have been ruled out
- Persistent depleted battery alarms indicate battery failure or internal power system fault
- Remove device from service
- Label Out of Service
- Send for battery replacement or bench evaluation
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device before addressing battery or power issues.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displayed 'Depleted Battery! Plug into AC now!' and could not maintain infusion on battery."
Cause
What was observed during troubleshooting.
Example:
"Battery voltage below threshold; condition persisted despite AC connection indicating battery degradation."
Resolution
What action was taken.
Example:
"Connected to AC power to maintain operation; removed device from service and sent for battery replacement."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Battery-related alarms are critical and must be addressed immediately. Always verify external power sources first, ensure patient safety, and escalate when battery performance is unreliable.
That is successful troubleshooting.
