What This Guide Helps With
Troubleshooting unavailable resuscitation support, incorrect blended oxygen, absent SpO₂ function, or accessory and supply issues before repair escalation.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
If the warmer is supporting an infant and the resuscitation module, blender, or SpO₂ function is unavailable or unreliable, notify clinical staff immediately.
Provide alternate approved resuscitation support, oxygen delivery, and pulse oximetry monitoring before beginning troubleshooting.
Do not troubleshoot neonatal resuscitation functions while they may be needed for active patient care.
Expected outcome: The infant is supported by known-working alternate equipment before the affected Giraffe Warmer is evaluated.
Why it matters: The Giraffe Warmer may be equipped with integrated T-piece or bag-and-mask resuscitation, an integrated blender, and SpO₂ monitoring options.
2. Confirm the Installed Configuration and Reported Failure
Verify which optional components are installed on the affected warmer:
- Resuscitation module present or absent
- T-piece or bag-and-mask configuration
- Integrated oxygen blender present or absent
- Integrated SpO₂ monitoring present or absent
Ask staff what occurred:
- No gas flow
- Incorrect or unstable oxygen concentration
- Inability to obtain expected pressure or ventilation support
- SpO₂ option unavailable, sensor not detected, or unreliable reading
- Error message, alarm, or intermittent operation
Expected outcome: The complaint is matched to an installed option rather than assuming a failure of equipment not configured on the unit.
3. Inspect the Device and Accessories Externally
With the warmer removed from service, inspect the resuscitation and SpO₂ areas for:
- Damaged, loose, cracked, or missing connectors
- Disconnected gas hoses
- Damaged patient circuit, T-piece, mask, tubing, or suction accessories
- Cracked flowmeter tube, damaged gauge, or loose control knobs
- Damaged SpO₂ patient cable, sensor, extension cable, or connector
- Evidence of liquid intrusion, unusual smell, impact damage, or contamination
Do not continue testing if physical damage or contamination could affect safe operation.
Expected outcome: Easily visible damage or disconnection is identified before functional testing.
If the problem is resolved by securely reconnecting an undamaged accessory, verify operation off-patient and stop troubleshooting.
4. Verify Warmer Power and Option Recognition
Power the warmer on while it is not in patient use. Confirm that the display initializes normally and that no system failure or option-related fault is present.
For an SpO₂ complaint, verify that the SpO₂ monitoring option appears available on the display when equipped. The warmer’s service checkout identifies oximetry as an installed option that should be recognized by the system.
Expected outcome: The warmer powers on normally and recognizes the installed monitoring option.
If the SpO₂ option is installed but does not appear, or a system fault remains active, remove the device from service and escalate for bench evaluation.
5. Check Medical Gas Supply Connections
For resuscitation or blender concerns, verify that the required medical gas hoses are properly connected to the correct wall outlets or approved gas source.
Inspect the external gas hoses and fittings for:
- Loose connections
- Damaged fittings
- Kinks or compression
- Incorrect outlet connection
- Absent air or oxygen supply where both are required for blended output
The optional integrated blender is designed to provide adjustable oxygen concentration from 21% to 100% when properly supplied with medical gas inputs.
Expected outcome: Correct external gas supplies are present, securely connected, and free of obvious damage.
If reconnecting the correct supply restores expected function, complete an off-patient verification and stop troubleshooting.
6. Evaluate Resuscitation Accessory Setup
If the complaint involves no flow, low flow, unstable pressure, or ineffective resuscitation output, inspect the attached patient circuit and accessories.
Check for:
- Kinked or occluded tubing
- Loose circuit connection
- Damaged or incorrectly assembled T-piece or bag-and-mask accessories
- Blocked outlet fitting
- Incorrect accessory attached to the configured resuscitation system
- Disposable component that requires replacement
Use an approved test setup according to department procedure to determine whether flow or pressure responds normally after replacing suspect disposable accessories.
Expected outcome: External circuit or accessory problems are corrected, or the problem remains isolated to the integrated resuscitation system.
If a known-good approved accessory restores expected performance, document the failed accessory and stop troubleshooting.
7. Inspect Blender Control and Output Concern
If the complaint involves oxygen concentration, inspect the blender externally.
Confirm that:
- The blender control knob is present and mechanically secure.
- The knob moves normally without looseness, binding, or excessive play.
- Required air and oxygen supplies are connected.
- Staff are not reporting inconsistent oxygen concentration despite correct external setup.
Do not attempt internal blender adjustment or calibration during initial troubleshooting.
Expected outcome: No visible control damage or external supply problem is present.
If the blender knob is loose, damaged, or output remains questionable, remove the device from service for resuscitation-system bench evaluation.
8. Troubleshoot the SpO₂ Connection Path
For an SpO₂ integration complaint, check the monitoring path externally:
- Verify the SpO₂ patient cable is fully seated.
- Inspect the cable and sensor for cuts, crushed areas, bent pins, contamination, or damaged connector housings.
- Confirm the sensor type is compatible with the installed SpO₂ technology and approved for the warmer.
- Replace the sensor or patient cable with a known-good approved accessory, when available.
- Observe whether the display recognizes the connected sensor and clears the reported fault.
Do not evaluate sensor performance on a patient while the monitoring function is considered unreliable.
Expected outcome: A defective or disconnected external SpO₂ accessory is identified, or the failure remains with the installed monitoring system.
If a known-good approved sensor or cable restores normal recognition, document the accessory replacement and stop troubleshooting.
9. Perform an Off-Patient Operational Verification
After correcting an external connection, supply, or accessory issue, verify the affected function while the unit remains out of clinical use:
- Resuscitation function responds as expected with the approved test setup.
- Blender control is secure and no concern remains regarding output selection.
- SpO₂ option recognizes approved accessories without an active fault.
- No system failure, alarm abnormality, gas leak concern, or intermittent behavior occurs.
Return the warmer to service only when the affected option operates reliably and all required departmental checks are completed.
Expected outcome: The repaired external issue is verified before clinical return.
If the Problem Persists
If correct power, medical gas supplies, external tubing, patient circuit accessories, blender controls, and approved SpO₂ accessories have been checked and the problem remains, common external causes have been ruled out.
The failure is likely associated with the integrated resuscitation system, blender, SpO₂ module, internal connection, or associated control electronics.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation according to Clinical Engineering procedure
Do not perform deeper internal repair, blender calibration, or module-level troubleshooting without the appropriate service documentation, test equipment, and authorization.
Knowing when to stop and escalate is proper troubleshooting, especially when neonatal resuscitation or oxygen monitoring capability may be affected.
Clinical Use Tip
Never troubleshoot a resuscitation, blender, or SpO₂ integration issue while an infant depends on the affected warmer. Provide alternate warming, ventilation support, oxygen delivery, and monitoring before evaluating the equipment.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the Giraffe Warmer’s integrated resuscitation system was available, but the blender output was questionable and the SpO₂ sensor would not register."
Cause
What was observed during troubleshooting.
Example:
"Inspection found the oxygen supply connected correctly, but the SpO₂ patient cable was damaged and the blender control remained loose during external inspection."
Resolution
What action was taken.
Example:
"Replaced the damaged SpO₂ cable for verification, removed the warmer from service due to unresolved blender concern, labeled it Out of Service, and routed it for bench evaluation."
Helpful Details to Include (If Known)
- Patient removed from affected warmer before troubleshooting
- Installed option confirmed: resuscitation module, blender, and/or SpO₂
- T-piece or bag-and-mask configuration identified
- Medical air and oxygen sources checked
- Gas hose and fitting condition
- Flow, pressure, or oxygen concentration complaint reported
- Blender knob condition
- SpO₂ sensor and cable swapped with approved known-good accessories
- Displayed faults or alarm behavior
- Any unusual sound, leak indication, heat, odor, or physical damage
- Final device status: returned to service or removed from service
Final Thought
A Giraffe Warmer resuscitation, blender, or SpO₂ integration issue can affect critical neonatal support. Start with patient safety, confirm the installed option, rule out external supplies and accessories, and escalate when reliable operation cannot be verified. Clear CCR documentation supports safe follow-up and effective repair.
That is successful troubleshooting.
