What This Guide Helps With
Troubleshooting Cardiosave battery charging, short battery runtime, AC power, dock, and transport power issues before escalation.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Do not troubleshoot power or battery problems while the patient is dependent on the IABP unless a safe clinical backup plan is in place.
Action:
- Confirm whether the pump is actively supporting a patient.
- If battery runtime is questionable, keep the pump connected to AC power when possible.
- If transport is needed, verify adequate battery status before leaving the care area.
- Have clinical staff prepare an alternate IABP or support plan if power reliability is uncertain.
Expected outcome: Patient support is maintained without relying on a pump with questionable battery performance.
Why it matters: IABP interruption during active therapy can create an immediate patient safety risk.
Verify the Reported Power Complaint
Confirm whether the issue is failure to charge, short runtime, unexpected shutdown, AC power failure, or transport-related battery depletion.
Action:
- Ask staff what happened:
- Battery would not charge
- Battery charged slowly
- Battery discharged faster than expected
- Pump shut down during transport
- Battery indicator dropped suddenly
- Pump did not recognize AC power
- Note whether the issue occurred on the Cardiosave Hybrid cart, Rescue configuration, transport setup, or during wall power use.
Expected outcome: The failure mode is clearly identified before parts or batteries are blamed.
Why it matters: A battery complaint may actually be caused by AC power, power cord, docking, charging contacts, loose connections, old batteries, or user workflow during transport.
Check AC Power at the Wall Outlet
Start with the simplest external cause.
Action:
- Verify the pump is plugged into a known-good hospital-grade outlet.
- Check that the outlet is not controlled by a wall switch.
- Test the outlet with another device or outlet tester if appropriate.
- Move the IABP to another verified outlet if the outlet is questionable.
Expected outcome: The pump should recognize AC power and begin charging if the battery and charging system are functional.
If this resolves the issue, stop and document the bad outlet or power source.
Inspect the Power Cord and Plug
Check for obvious external damage before suspecting internal charging failure.
Action:
- Inspect the power cord for cuts, kinks, crushed insulation, bent blades, loose plug fit, or strain relief damage.
- Confirm the cord is fully seated at the pump or cart connection point.
- Swap with a known-good compatible power cord if allowed by site policy.
Expected outcome: The pump should remain stable on AC power and show charging behavior when connected.
If the issue follows the cord, remove the damaged cord from service and replace it.
Confirm AC Power Indicator and Charging Status
Verify what the device is actually reporting.
Action:
- Connect the pump to known-good AC power.
- Observe AC power indicators, battery icons, charging status, and any power-related messages.
- Allow several minutes for the display to update if the battery was deeply discharged.
- Record any error messages or abnormal indicator behavior.
Expected outcome: The device should indicate AC power is present and show that the battery is charging or already charged.
Why it matters: A battery that does not appear to charge may be fully charged, too depleted to update immediately, not seated correctly, or unable to accept charge.
Check Battery Installation and Seating
A poorly seated battery can mimic a failed battery or charger.
Action:
- Power the device down only when clinically safe.
- Confirm the battery is properly installed and latched.
- Remove and reseat the battery if this is permitted by site procedure and safe to do.
- Inspect the battery compartment area for debris, obvious contact damage, broken latch parts, or fluid contamination.
- Do not force the battery into place.
Expected outcome: The pump should recognize the installed battery and display appropriate battery/charging status.
If reseating restores normal charging, document the battery seating issue and verify stable operation before returning to use.
Inspect the Battery Pack Externally
Look for signs that the battery should not be used.
Action:
- Check the battery for cracks, swelling, leakage, corrosion, broken casing, damaged label, damaged contacts, or evidence of impact.
- Remove any physically damaged battery from service.
- Do not attempt to charge or use a battery that appears swollen, leaking, overheated, or physically compromised.
Expected outcome: Only batteries in good physical condition remain available for use.
Why it matters: Damaged rechargeable batteries can create power reliability and safety hazards.
Try a Known-Good Battery
Separate a battery failure from a pump charging issue.
Action:
- Install a known-good charged battery, if available.
- Confirm the pump recognizes it.
- Connect the pump to AC power and verify charging status.
- Compare behavior with the suspect battery.
Expected outcome:
- If the known-good battery works normally, the original battery is likely weak, depleted, expired, or failed.
- If no battery charges or is recognized, suspect a pump-side charging, connection, or power management issue.
If the battery is confirmed bad, remove it from service and replace per facility procedure.
Check Battery Age and Service History
Short runtime is often caused by battery age or repeated deep discharge.
Action:
- Review the battery install date, service date, or replacement history if available.
- Check prior work orders for short runtime, charging complaints, power loss, or transport shutdowns.
- Compare reported runtime with expected clinical use and transport requirements.
Expected outcome: Aged or repeatedly problematic batteries are identified for replacement instead of repeatedly returned to service.
Why it matters: Rechargeable batteries are consumable items and can pass basic recognition checks while still having poor capacity.
Verify Charging Time and Runtime Under Safe Conditions
Do not judge battery health from a quick plug-in unless the complaint is obvious.
Action:
- Charge the pump on known-good AC power for an appropriate period per facility practice.
- Perform a controlled battery runtime check only in a safe bench or non-patient setting.
- Monitor for sudden drops, rapid discharge, unexpected shutdown, charging failure, or abnormal heat.
Expected outcome: Battery charge and discharge behavior should be stable and predictable.
If runtime is short after proper charging, replace the battery or escalate for evaluation.
Check Transport Setup and Workflow
Transport complaints may be caused by starting transport with insufficient battery charge.
Action:
- Confirm the battery was fully charged before transport.
- Confirm the pump was not left unplugged before transport.
- Ask whether the pump was running on battery longer than expected before the move.
- Verify staff are using the correct transport power workflow for the Cardiosave configuration.
Expected outcome: The device has enough battery capacity before leaving AC power.
Why it matters: A good battery can still fail transport expectations if the pump starts transport partially discharged.
Check for Docking or Cart Power Issues
For Cardiosave Hybrid configurations, verify the cart/power setup is not the source of the problem.
Action:
- Confirm the pump is correctly seated or connected in its intended configuration.
- Inspect external power/docking connections for looseness, damage, debris, or poor alignment.
- Check whether the issue occurs only on one cart, dock, location, or power setup.
- Try another known-good compatible setup if available and allowed.
Expected outcome: Charging and AC recognition should be consistent across proper power configurations.
If the issue only occurs with one cart, dock, or setup, remove that configuration from service for evaluation.
Look for Heat, Smell, Noise, or Intermittent Power
Do not continue troubleshooting if there are signs of electrical failure.
Action:
- Check for unusual heat near the battery, charger area, power inlet, or cord.
- Smell for burning odor.
- Listen for abnormal buzzing, clicking, or intermittent power cycling.
- Observe whether the pump reboots, flickers, or loses AC power when the cord is gently moved.
Expected outcome: The device should remain electrically stable with no heat, odor, or intermittent power behavior.
If heat, odor, smoke, arcing, or repeated power cycling is present, stop troubleshooting and remove the device from service.
Perform Final Functional Verification
Before returning the pump to service, verify stable operation.
Action:
- Confirm the pump powers on normally.
- Confirm AC power is recognized.
- Confirm battery status is displayed.
- Confirm charging behavior appears normal.
- Confirm the battery remains seated and recognized.
- Confirm no power-related alarms or messages remain.
- Confirm the device is safe for clinical use per department policy.
Expected outcome: The IABP is stable on AC power and battery status is reliable.
If the issue is resolved, return the device to service and document clearly.
If the Problem Persists
If the Cardiosave still does not charge, has short runtime after proper charging, does not recognize known-good batteries, shuts down unexpectedly, or has intermittent AC/battery behavior, common external causes have been ruled out.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Possible internal causes may include battery failure, charging circuit failure, power supply issue, battery communication issue, damaged battery contacts, internal cabling fault, or power management board failure.
Knowing when to stop is proper troubleshooting. Do not attempt deep internal repair or continued clinical use when IABP power reliability is uncertain.
Clinical Use Tip
Never troubleshoot power reliability on a Cardiosave IABP while the patient is dependent on it unless clinical staff have a safe backup plan in place. Move the patient to a backup device or alternate support plan first if battery, AC power, or transport power reliability is uncertain. Therapy continuity must come before troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported the Getinge Cardiosave Hybrid battery was not charging and the pump had short runtime during transport preparation."
Cause
What was observed during troubleshooting.
Example:
"Verified outlet and power cord were good, but the installed battery was not holding charge after proper AC charging and runtime check."
Resolution

Final Thought
Battery and transport power issues on an intra-aortic balloon pump must be treated as patient safety concerns first. Start with power source, cord, battery seating, and known-good battery checks before suspecting internal failure. If power reliability cannot be verified, remove the pump from service and escalate appropriately. Clear CCR documentation helps show what was checked, what was found, and why the device was returned to service or sent for repair.
That is successful troubleshooting.
