What This Guide Helps With
Addresses an unrecognized imaging component caused by connection, compatibility, contamination, cable, power, or configuration problems.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Airway Readiness
Do not troubleshoot an unreliable video laryngoscope while it is being used for airway management. Transfer immediately to another verified airway device and ensure an appropriate backup airway method is available.
Inspect the GlideScope system for impact damage, exposed conductors, liquid intrusion, unusual heat, odor, or visibly damaged connectors. Remove the equipment from service immediately if any unsafe condition is found.
Expected outcome: The patient is supported with reliable airway equipment, and the GlideScope system is safe to evaluate.
2. Confirm the Exact Recognition Failure
Ask clinical staff which video baton, camera, or handle was connected, whether the failure occurred at startup or during use, and whether any message or blank-image condition appeared.
Reproduce the complaint away from patient care using the same monitor, imaging component, cable, and accessories when safe.
Expected outcome: The affected component and exact failure condition are identified. If the system now recognizes the component consistently, complete functional verification and stop troubleshooting.
3. Verify Monitor Power and Normal Startup
Confirm the monitor powers on normally and reaches its standard operating screen without freezing, restarting, or displaying unrelated power problems.
If available, verify operation on both approved AC power and a sufficiently charged battery.
Expected outcome: The monitor starts normally and remains stable. If monitor power is unreliable, address the power issue before continuing recognition troubleshooting.
4. Reseat All External Connections
Power down the system when appropriate. Disconnect the video baton, camera, or handle and any intermediate video cable. Inspect each connector for incomplete seating, bent contacts, debris, moisture, corrosion, or damaged alignment features.
Reconnect each component fully without forcing the connector. Confirm any locking or retention feature engages normally.
Expected outcome: All connections are clean, dry, undamaged, and fully seated. If recognition returns and remains stable after repeated reconnection, troubleshooting can stop after final verification.
5. Confirm Component Compatibility
Verify that the connected video baton, camera, handle, cable, and monitor are approved for use together within the specific GlideScope configuration.
Compare model labels, connector types, and facility inventory records. Do not force physically similar components together or change restricted configuration settings.
Expected outcome: All connected components are confirmed compatible. An incompatible component is replaced with the correct approved component.
6. Inspect the Imaging Component and Cable
Examine the video baton, camera, or handle for cracks, damaged strain reliefs, contamination, loose housings, or evidence of fluid entry. Inspect the full cable length for cuts, kinks, compression, or intermittent movement at either end.
Do not use a component that cannot be cleaned, disinfected, or safely connected according to facility and manufacturer requirements.
Expected outcome: The component and cable show no visible defect. Any damaged item is removed from service.
7. Test With a Known-Good Compatible Component
Connect a known-good compatible video baton, camera, handle, or cable one item at a time. Keep the original monitor and remaining accessories unchanged so the result isolates the affected part of the external system.
Do not substitute unapproved accessories.
Expected outcome: The known-good component is recognized consistently. If it is, remove the original component from service and complete final verification with the replacement.
8. Compare the Suspect Component on Another Compatible System
When available, connect the suspect component to another verified compatible GlideScope monitor. Follow infection prevention requirements before transferring reusable airway components between systems.
Expected outcome: The comparison determines whether the issue follows the imaging component or remains with the original monitor. Stop troubleshooting once the defective external component is isolated and removed from use.
9. Perform Final Functional Verification
Reconnect the verified components and power-cycle the system. Confirm recognition at startup, stable live video, proper orientation, acceptable image quality, and reliable operation while gently moving the external cable within normal handling limits.
Perform any required post-service inspection or electrical safety testing appropriate to the work performed.
Expected outcome: The system recognizes the imaging component repeatedly and maintains a stable image. The device may be returned to service only after all required checks pass.
10. Escalate an Unresolved Recognition Failure
If compatible known-good external components are still not recognized, discontinue external troubleshooting. Do not enter unauthorized service modes, open sealed assemblies, or attempt board-level repair.
Expected outcome: The system is removed from clinical use and routed for qualified service evaluation.
If the Problem Persists
Common external causes such as incomplete connections, contamination, visible cable damage, accessory compatibility, and defective interchangeable components have been ruled out. The remaining cause may involve the monitor input, internal connector assembly, imaging electronics, software, or authorized configuration.
Remove the device from service, label it Out of Service, and send it for repair or bench evaluation. Evaluate it using the correct Verathon documentation and approved test equipment. Repairs or configuration changes must be completed only by qualified personnel.
Before return to service, verify component recognition, live image stability, control operation, battery and AC operation as applicable, and all required safety checks. Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Keep a verified backup laryngoscope immediately available whenever airway visualization equipment shows intermittent recognition or image loss.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the GlideScope monitor did not recognize the connected video baton during setup."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found that the video cable connector was not fully seated and had visible debris around the connector interface."
Resolution
What action was taken.
Example:
"Clinical Engineering cleaned the external connector area, reconnected the cable securely, and verified repeated component recognition with a stable live image."
Helpful Details to Include (If Known)
- Exact component not recognized
- Message or screen condition observed
- Monitor power source
- Component and cable model identifiers
- Connector condition
- Evidence of moisture or contamination
- Known-good substitutions performed
- Whether the issue followed the component
- Live-image stability after correction
- Final device status
Final Thought
Protect the airway first, verify compatibility and external connections before assuming internal failure, stop when safe external checks are exhausted, and document the complaint, confirmed cause, corrective action, and final verification clearly.
That is successful troubleshooting.
