What This Guide Helps With
This guide assists in identifying and managing internal battery degradation in the CareFusion AVEA. Battery issues can reduce transport runtime, prevent proper battery charging, and trigger low-battery alarms.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm the ventilator is not actively supporting a patient during testing.
- If the patient is on this device, transfer them to another ventilator to maintain uninterrupted ventilation.
Check External Power and Charging
- Verify the AC power cord is fully connected and the outlet is functional.
- Observe the charging indicator on the ventilator. A healthy battery should indicate charging when plugged in.
Inspect Battery Connection and Condition
- Remove and reseat the internal battery following manufacturer guidelines.
- Check for visible damage, corrosion, or swelling of the battery.
Run Battery Self-Test (If Available)
- Use the ventilator’s built-in battery test function.
- Record reported runtime and health status. Compare to expected specifications.
Assess Runtime Performance
- Disconnect the ventilator from AC power and monitor how long it runs on battery alone.
- If runtime is significantly below specifications or the ventilator shuts down prematurely, this confirms battery degradation.
Replace Battery If Necessary
- If degradation is confirmed, schedule internal battery replacement following manufacturer procedures.
- Use only approved CareFusion replacement batteries.
If the Problem Persists
If external checks and battery replacement do not resolve the issue:
- Remove the ventilator from service.
- Label as Out of Service.
- Send the device for manufacturer or qualified repair service.
Knowing when to stop is proper troubleshooting and prevents patient risk.
Clinical Use Tip
Never rely on a degraded battery during patient transport or in critical care situations.
Regularly schedule battery checks and replacements to avoid unexpected failures.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
Ventilator battery does not hold charge; runtime is below specification.
Cause
Internal battery has degraded and cannot sustain proper operation.
Resolution
What action was taken.
Example:
Battery replaced with manufacturer-approved unit; ventilator tested and returned to service.
Helpful Details to Include (If Known)
- AC outlet functional and verified
- Charging indicator behavior
- Battery physical condition
- Measured runtime on battery-only operation
- Final ventilator status post-replacement
Final Thought
Battery degradation is a predictable maintenance issue. Logical, stepwise verification ensures patient safety and prevents downtime during critical care. Proper documentation supports maintenance records and justifies timely battery replacement.
That is successful troubleshooting.
