What This Guide Helps With
Troubleshooting unavailable network communication, failed data export, or missing patient-monitor information caused by connections, configuration, network, interface, or downstream system problems.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
Do not perform extended communication troubleshooting while the Carestation 600 Series is supporting an active patient.
If networked data, electronic charting, or patient-monitor communication fails during a case:
- Confirm that ventilation, gas delivery, alarms, and required measurements remain available locally.
- Notify the anesthesia provider of the communication failure.
- Use approved independent monitoring and downtime documentation procedures.
- Move the patient to another verified anesthesia machine if local therapy or monitoring performance is also questionable.
Expected outcome: Patient care remains supported by functional local equipment and does not depend on the failed external interface.
Continue troubleshooting only when the device can be evaluated safely without disrupting patient care.
2. Confirm the Exact Failure
Determine which function is affected:
- Network connection unavailable
- Data not reaching the anesthesia record or EMR
- Patient-monitor values not appearing on the anesthesia system
- Anesthesia data not appearing on the patient monitor
- USB or other supported data export failing
- Communication working intermittently
- One interface failing while other network functions remain available
Record any displayed communication message, network symbol, timestamp, or status indicator.
Expected outcome: The affected communication path and direction of data flow are clearly identified.
3. Confirm Local Anesthesia Functions
Verify that the Carestation:
- Powers on normally
- Completes its required checkout
- Displays ventilation and gas information locally
- Responds normally to controls
- Produces expected alarms
- Maintains the correct date and time
A communication problem should not automatically be treated as an anesthesia-delivery failure.
Expected outcome: Local operation is normal and the problem is isolated to communication or data transfer.
If local monitoring or therapy is also abnormal, stop and remove the device from service.
4. Inspect External Communication Connections
Inspect all accessible communication cables between the Carestation, patient monitor, network outlet, interface device, and any approved serial or integration hardware.
Check for:
- Loose connectors
- Partially seated plugs
- Bent connector pins
- Damaged locking tabs
- Crushed or sharply bent cables
- Contamination or fluid exposure
- Cables connected to the wrong port
- Unapproved adapters or extensions
Reseat connections only after confirming that doing so will not interrupt active patient care.
Expected outcome: All external communication connections are secure and undamaged.
If reseating restores communication, verify stable data transfer and stop troubleshooting.
5. Verify the Network Outlet and Patch Cable
When Ethernet communication is involved:
- Confirm that the cable is connected to the designated network port.
- Inspect the network jack and cable for damage.
- Check for available link or activity indicators, when visible.
- Test the patch cable with a known-good approved cable.
- Confirm that the wall outlet is the correct active network outlet for the anesthesia system.
Do not move the device to an arbitrary network jack because ports may be assigned to different networks or security profiles.
Expected outcome: The Carestation has a verified physical connection to the correct network.
If the replacement cable restores communication, replace the defective cable and stop.
6. Compare With a Known-Good Location or Device
Determine whether the failure follows:
- The Carestation
- The communication cable
- The wall network port
- The patient monitor
- The room
- The integration interface
When approved by the facility, connect the affected device using a known-good cable and validated interface location.
Avoid changing multiple components simultaneously.
Expected outcome: Testing identifies whether the problem is device-specific or external to the Carestation.
If another Carestation also fails at the same location, investigate the network port or downstream integration system.
7. Check the Patient Monitor and Interface Equipment
Verify that the connected patient monitor or interface device:
- Is powered on
- Is operating normally
- Recognizes its network or communication connection
- Uses the correct interface cable
- Has not been replaced, moved, or reconfigured
- Is not displaying its own communication error
- Can communicate with other connected systems
If a bedside monitor was recently exchanged, confirm that the replacement device was properly assigned and configured.
Expected outcome: The downstream monitor or interface is available and correctly connected.
If the downstream device is the source of the failure, redirect the repair to the responsible equipment or support team.
8. Check for Recent Environmental or System Changes
Ask whether the problem began after:
- A Carestation or monitor replacement
- Software maintenance
- Network switch work
- A room renovation
- Device relocation
- Cable replacement
- EMR or anesthesia-record system maintenance
- Changes to device names, addresses, or room assignments
- A facility network outage
A configuration mismatch is likely when communication stops immediately after a known change.
Expected outcome: Any recent change associated with the failure is identified.
9. Review Accessible Communication Settings
Using only authorized Clinical Engineering access, verify that applicable communication settings match the facility’s approved configuration.
Check available information such as:
- Device or host name
- Network address settings
- Interface selection
- Patient-monitor communication selection
- Data-export destination
- Room or bed assignment
- Date and time
- Enabled communication options
Do not guess network values, copy settings from an unrelated room, or change protected service parameters without an approved configuration record.
Expected outcome: Accessible settings match the documented configuration for the device and location.
GE directs service-related procedures and special installation requirements to authorized technical documentation; avoid undocumented configuration changes.
10. Restart the Communication Path Safely
When the device is off patient and facility procedures allow:
- Close any active cases appropriately.
- Shut down the Carestation using the normal shutdown process.
- Restart connected interface equipment in the approved order.
- Restart the Carestation.
- Allow all systems to complete initialization.
- Recheck connection status and data transfer.
Do not disconnect power abruptly unless specifically required by an approved service procedure.
Expected outcome: Communication initializes normally after an orderly restart.
If communication returns, perform repeated verification before returning the device to service.
11. Verify Data Transfer With a Controlled Test
Use a facility-approved test patient, simulator, or validation workflow.
Confirm that:
- The correct Carestation is associated with the correct room or monitor.
- Expected parameters are generated locally.
- Values appear at the intended destination.
- Timestamps are correct.
- Data remain stable without repeated dropouts.
- No information is assigned to the wrong patient or location.
Do not use real patient identifiers for informal testing.
Expected outcome: Accurate information transfers consistently to the correct destination.
If the test succeeds, document the findings and return the device to service according to facility policy.
12. Coordinate With Network or Integration Support
If physical connections and device settings appear correct, contact the appropriate network, middleware, anesthesia-information-system, or clinical-integration team.
Provide:
- Device model and serial number
- Equipment hostname or approved network identifier
- Room and network outlet
- Time the failure occurred
- Destination system affected
- Whether link indicators are present
- Results from cable and outlet testing
- Whether other devices are affected
- Any recent network or software changes
Request verification of network access, interface status, message receipt, device association, and downstream server availability.
Expected outcome: The responsible team can determine whether the failure exists outside the anesthesia machine.
13. Perform Final Operational Verification
After communication is restored:
- Confirm normal local anesthesia operation.
- Complete the required system checkout.
- Verify communication using the approved test workflow.
- Confirm correct patient, room, and device association.
- Observe for intermittent connection loss.
- Remove all test information according to facility procedure.
Expected outcome: The Carestation passes its checkout and communicates accurately and consistently.
If communication remains unstable, do not return the device to clinical service when the interface is required for safe or approved operation.
If the Problem Persists
If cables, network access, downstream equipment, accessible settings, and external systems have been verified, the failure may involve an internal communication interface, software configuration, port hardware, or system-level integration problem.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for authorized repair or bench evaluation
- Escalated to GE Healthcare and the facility’s network or integration team as appropriate
Do not perform undocumented internal disassembly, board replacement, or service-level configuration changes.
Knowing when external causes have been ruled out and escalation is required is proper troubleshooting.
Clinical Use Tip
Do not troubleshoot the Carestation 600 Series while it is supporting an active patient. Move the patient to a verified backup device first and maintain therapy continuity throughout the equipment change.
Networked data and automated charting are conveniences only when the underlying local monitoring remains verified. Never rely on a remote display or electronic record as the sole indication of ventilation, gas delivery, or patient condition.

Final Thought
Communication failures should be separated from actual anesthesia-delivery failures through patient-safety checks and controlled testing. Verify physical connections and external systems before suspecting internal hardware, and document the complete communication path so the correct support team can act efficiently.
That is successful troubleshooting.
