What This Guide Helps With
Troubleshoots reported battery or backup-power problems by verifying the device configuration, AC supply, external power support, charging indications, and operating conditions.
Step-by-Step Troubleshooting
1. Protect the Patient and Confirm Alternate Power
Do not rely on uncertain battery or backup operation during a procedure. If continued AirSeal support is required, connect the system to a verified approved power source or provide an alternate device as appropriate.
Expected outcome: Clinical support does not depend on an unverified battery or backup source.
2. Verify the Actual Equipment Configuration
Confirm whether the specific AirSeal iFS configuration being reported has the battery or backup-power capability staff are referring to. Determine whether the complaint actually involves:
- The AirSeal iFS itself.
- A cart or external UPS.
- Another connected accessory.
- Loss of AC power interpreted as a battery failure.
Do not assume a battery is present or field-serviceable without confirming the configuration.
Expected outcome: The reported battery problem is associated with the correct device or external power component.
3. Confirm AC Input
Inspect the power cord and accessible power connections. Verify the receptacle using an approved method and make sure the system receives stable AC power.
If an external UPS or power-support device is used, verify its AC input and normal status separately.
Expected outcome: A known-good AC source is available to the device or applicable backup-power system.
4. Check Charging or Power Status Indications
Observe available status indicators while the system is connected to verified AC power. Record any message or indicator exactly.
Do not interpret an unfamiliar indicator as a battery failure without checking approved documentation.
Expected outcome: Power or charging status is consistent with the installed configuration and operating state.
5. Inspect Accessible Power Accessories
Inspect external UPS cables, power adapters, detachable power cords, connectors, and other accessible power accessories associated with the complaint.
Look for:
- Loose connections.
- Damaged cables.
- Bent contacts.
- Heat discoloration.
- Fluid contamination.
- Mechanical damage.
Expected outcome: All external power components are properly connected and undamaged.
6. Compare With a Known-Good External Component When Appropriate
If the reported problem involves an approved interchangeable external power component, substitute a known-good compatible component according to facility procedures.
Do not substitute unapproved power supplies, batteries, or UPS devices.
Expected outcome: Normal operation with a known-good external component isolates the defective external component. If resolved, replace or remove that component and proceed to verification.
7. Evaluate the Reported Runtime Condition
If backup operation is applicable, establish how staff determined that runtime was short. Note whether the device had adequate time on AC power beforehand and whether the complaint occurred repeatedly under comparable conditions.
Do not perform an uncontrolled runtime depletion test on equipment needed for patient care.
Expected outcome: The runtime complaint is reproducible and not simply the result of incomplete charging, loss of AC input, or confusion about the device configuration.
8. Check Operating Environment
Verify that ventilation is unobstructed and the system or associated power-support equipment is not exposed to excessive heat, blocked airflow, or other conditions that could affect reliable operation.
Expected outcome: No obvious environmental problem is contributing to the power complaint.
9. Perform Final Functional Verification
After correcting an external power problem, verify normal AC operation, applicable status indications, startup, alarms, controls, and intended functions using approved procedures.
Expected outcome: The device operates reliably with no recurring power or charging complaint. Troubleshooting can stop.
10. Escalate Unresolved Battery or Backup-Power Concerns
If the correct configuration has been confirmed and external AC power, cables, and applicable external power components are satisfactory but the problem remains, discontinue external troubleshooting.
Expected outcome: The affected device or power-support component is removed from service and referred for qualified evaluation.
If the Problem Persists
Common external causes have been ruled out. Remaining possibilities include an internal power-storage component where applicable, charging circuitry, power-management electronics, configuration, or an external UPS requiring separate service.
The affected equipment should be:
- Removed from service.
- Labeled Out of Service.
- Sent for repair or bench evaluation.
- Evaluated using appropriate manufacturer documentation and approved test equipment.
- Repaired or configured only by qualified personnel.
Complete the appropriate operational and electrical safety checks after repair before return to service.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Never plan continued procedural support around uncertain backup runtime; establish a verified AC source or substitute equipment first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported that the AirSeal iFS lost power shortly after being disconnected from the procedure-room power source."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering determined the reported backup source was an external cart UPS that was not receiving AC power."
Resolution
What action was taken.
Example:
"Restored AC power to the external power system, verified normal device operation and power indications, and returned the setup to service."
Helpful Details to Include (If Known)
- Whether backup power is part of the actual configuration.
- Whether an external UPS is involved.
- AC source tested.
- Power and charging indicators observed.
- External cable and connector condition.
- Known-good substitutions.
- Conditions surrounding the reported short runtime.
- Whether the problem was reproducible.
- Final device and power-source status.
Final Thought
Confirm what equipment actually provides backup power before diagnosing a battery failure. Patient safety, verified AC supply, careful external inspection, appropriate escalation, and accurate CCR documentation prevent unnecessary parts replacement and unsafe assumptions.
That is successful troubleshooting.
