What This Guide Helps With
Troubleshoots startup failure, delayed booting, or unexpected restarts caused by power, connection, battery, accessory, or environmental problems.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Thermal Support
Do not troubleshoot an OmniBed that is providing required thermal support to an infant if its operation is unreliable. Transfer the patient to another verified incubator or warmer according to clinical procedure before continuing.
Inspect for smoke, unusual odor, excessive heat, liquid intrusion, or visible electrical damage. Disconnect the unit from AC power and remove it from service immediately if any of these conditions are present.
Expected outcome: The patient is safely supported by reliable equipment, and the OmniBed is safe to evaluate.
2. Confirm the Reported Power Condition
Determine exactly what staff observed:
- Completely dead unit
- Delayed display or startup
- Startup that repeatedly cycles
- Restart while operating
- Problem occurring only after unplugging from AC
- Intermittent problem associated with movement
Attempt a controlled startup without a patient and observe the display, indicators, alarms, and sequence of operation.
Expected outcome: The failure is reproduced or clearly characterized. If the unit now starts normally and remains stable, continue through basic checks before returning it to service.
3. Verify AC Power at the Source
Confirm the power cord is fully connected to the OmniBed and an approved receptacle. Inspect the cord and plug for cuts, bent blades, looseness, discoloration, or damaged strain relief.
Verify the receptacle with appropriate approved test equipment or a known-good device. If the OmniBed was connected through an extension, adapter, or questionable power source, remove that variable.
Expected outcome: Stable facility power is available and the power cord is securely connected. If correcting the outlet or connection restores reliable startup, perform final verification and troubleshooting can stop.
4. Inspect External Power Connections
With the device removed from patient use, inspect accessible power-entry connections and surrounding areas for looseness, contamination, impact damage, or evidence that movement of the cord affects operation.
Do not open power assemblies or perform internal power-supply troubleshooting as part of this external guide.
Expected outcome: External power connections are secure and undamaged.
5. Compare AC and Battery Behavior
With the unit operating normally on AC, observe its indicated power and charging status. If appropriate for the configuration and facility procedure, briefly compare operation after AC is removed.
A unit that operates normally on AC but immediately shuts down or restarts when unplugged points toward the battery or battery-support system rather than the main AC source.
Expected outcome: The problem is isolated to AC operation, battery operation, or both.
6. Remove Nonessential External Accessories
Disconnect nonessential externally connected accessories or communication cables that can safely be removed for testing. Restart the OmniBed and observe whether startup becomes normal.
Reconnect accessories individually if necessary to identify whether an external connection is associated with the restart.
Expected outcome: The unit starts and remains stable with normal external connections. If one removable accessory or cable is clearly responsible, correct or replace it and troubleshooting can stop after verification.
7. Check Environmental and Mechanical Factors
Confirm ventilation openings are unobstructed and the unit is not exposed to excessive heat, fluid contamination, or other environmental conditions that could affect operation.
If restarts occur when the unit is moved, gently inspect the external power cord and accessible connectors without manipulating internal wiring.
Expected outcome: No external environmental or movement-related condition explains the failure.
8. Perform Final Functional Verification
After correcting an external cause, restart the OmniBed multiple times as appropriate and allow it to complete its normal startup sequence. Verify the display, controls, alarms, thermal-system readiness, and other required functions before return to service.
Expected outcome: Startup is repeatable, operation remains stable, and required functions pass the facility's return-to-service checks. Troubleshooting can stop.
If the Problem Persists
If verified AC power, the power cord, accessible connections, battery-related behavior, accessories, and environmental causes have been ruled out, the problem may involve an internal power supply, battery-management circuit, processor, display electronics, wiring, or another service-level fault.
The OmniBed should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using current GE Healthcare service documentation and approved test equipment
- Repaired or configured only by qualified personnel
Do not continue operating an incubator that randomly restarts or cannot complete a reliable startup. Complete manufacturer-required functional, electrical-safety, and applicable thermal-system testing before return to clinical use.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
A restarting OmniBed can interrupt thermal support and alarm capability; move the infant to another verified device before troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"NICU staff reported that the Giraffe OmniBed Carestation intermittently restarted during startup."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the AC power cord was not fully seated at the equipment connection and movement caused intermittent power loss."
Resolution
What action was taken.
Example:
"Reseated and secured the power connection, verified repeated normal startups and stable operation, and completed functional checks before returning the unit to service."
Helpful Details to Include (If Known)
- Whether the unit was completely dead or restarted
- AC or battery operation when failure occurred
- Outlet test result
- Power cord and plug condition
- Charging indication
- Whether movement affected operation
- External accessories connected during failure
- Startup messages or indicators observed
- Evidence of heat, odor, liquid, or physical damage
- Results of repeated startup testing
- Final device status
- Whether the unit was completely dead or restarted
- AC or battery operation when failure occurred
- Outlet test result
- Power cord and plug condition
- Charging indication
- Whether movement affected operation
- External accessories connected during failure
- Startup messages or indicators observed
- Evidence of heat, odor, liquid, or physical damage
- Results of repeated startup testing
- Final device status
Final Thought
Protect the patient first, establish whether the failure follows the power source or an external connection, and verify stable operation before assuming an internal fault. Escalate unreliable power problems appropriately and document the confirmed complaint, cause, corrective action, and final testing.
That is successful troubleshooting.
