What This Guide Helps With
Troubleshoots unavailable oxygen control or readings caused by configuration, gas supply, hose connections, sensor conditions, setup, or service-level oxygen faults.
Step-by-Step Troubleshooting
1. Protect the Infant and Maintain Prescribed Oxygen Therapy
Do not troubleshoot an unavailable or unreliable oxygen-control system while an infant depends on it for prescribed oxygen therapy.
Provide an alternate verified oxygen-delivery and monitoring method according to clinical procedure before continuing.
Expected outcome: The infant continues to receive appropriate oxygen independently of the questionable OmniBed function.
2. Confirm the Installed Configuration and Complaint
Determine whether the OmniBed is equipped and configured with the oxygen-control option applicable to the reported function.
Clarify whether:
- The oxygen control is unavailable
- The displayed oxygen value is missing
- The value appears inaccurate
- Oxygen does not increase when commanded
- The problem occurs only after startup
- The feature was previously available
Expected outcome: The actual installed function and reported failure are clearly established.
3. Verify the Gas Supply
Inspect the external oxygen supply source and hose. Confirm the correct gas source is being used and that the connection is secure.
Check for:
- Disconnected hose
- Kinked hose
- Damaged fitting
- Closed or unavailable source
- Obvious leak
- Incorrect gas connection
Use only approved gas-specific connections and accessories.
Expected outcome: A valid oxygen supply reaches the OmniBed. If restoring the supply returns normal operation, troubleshooting can stop after verification.
4. Inspect External Oxygen Connections
Examine accessible hose fittings, inlets, and related connections for looseness, contamination, physical damage, or evidence of leakage.
Do not apply lubricants or unauthorized sealants to medical-gas fittings.
Expected outcome: External gas connections are intact, secure, and leak-free.
5. Verify Operating Mode and Setup
Confirm the OmniBed is in the intended operating configuration and that the oxygen function is available under the selected mode and installed options.
Review only normal authorized settings. Do not modify restricted configuration values solely to make a missing function appear.
Expected outcome: The oxygen function is being tested under a valid configuration.
6. Allow Sensors to Stabilize
If the unit has recently powered on, been moved, or experienced a significant environmental change, allow the oxygen-measurement system to stabilize as required by applicable documentation.
Do not diagnose a sensor from a transient startup condition alone.
Expected outcome: The oxygen reading becomes available and stable if no actual fault is present.
7. Compare With an Approved Oxygen Analyzer
Using a calibrated oxygen analyzer and the approved service test method, compare the OmniBed's indicated oxygen concentration with an independent measurement.
Do not use smell, perceived flow, or an unverified portable sensor to assess oxygen accuracy.
Expected outcome: The displayed oxygen reading agrees with the approved reference within applicable manufacturer requirements.
8. Inspect for Obvious Sensor or Airflow Conditions
Inspect accessible sensor and airflow areas for contamination, moisture, obstruction, or other conditions that could affect measurement.
Do not replace or calibrate internal oxygen components without the applicable authorized service procedure.
Expected outcome: External contamination or airflow problems are ruled out.
9. Perform Approved Oxygen-System Verification
If the problem remains, qualified personnel should perform the appropriate manufacturer oxygen-system checks, including calibration or supply-system testing where applicable.
Do not bypass gas-control safeguards or adjust oxygen delivery based on an unverified internal setting.
Expected outcome: Oxygen measurement and control pass applicable service verification.
If the Problem Persists
If configuration, gas supply, hoses, fittings, stabilization, and independent oxygen measurement have been addressed, the problem may involve an oxygen sensor, valve or blender system, calibration, pressure or flow control, internal gas path, wiring, or electronic control system.
The OmniBed should be:
- Removed from service when integrated oxygen delivery or measurement is required
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using current GE Healthcare documentation, approved gas supplies, and calibrated oxygen test equipment
- Repaired or calibrated only by qualified personnel
Complete applicable gas-leak, oxygen-control, oxygen-measurement, alarm, and functional testing before return to service.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Never use the OmniBed's oxygen display as the sole basis for therapy when its oxygen-control or measurement system is under investigation.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"NICU staff reported that the OmniBed oxygen control was unavailable during setup."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the external oxygen supply hose disconnected from the unit."
Resolution
What action was taken.
Example:
"Restored the approved oxygen supply connection, verified oxygen control and measurement with calibrated test equipment, and completed functional testing."
Helpful Details to Include (If Known)
- Whether oxygen option is installed
- Oxygen control availability
- Displayed oxygen value
- External gas source
- Hose and fitting condition
- Supply connection status
- Operating mode
- Independent oxygen-analyzer result
- Calibration or functional-test result
- Leak indication
- Final device status
- Whether oxygen option is installed
- Oxygen control availability
- Displayed oxygen value
- External gas source
- Hose and fitting condition
- Supply connection status
- Operating mode
- Independent oxygen-analyzer result
- Calibration or functional-test result
- Leak indication
- Final device status
Final Thought
Confirm the installed configuration and external oxygen supply before assuming a failure inside the OmniBed. Because oxygen concentration directly affects neonatal care, independently verify questionable readings and escalate any control system that cannot be proven reliable.
That is successful troubleshooting.
