What This Guide Helps With
Troubleshoots temperature or humidification concerns involving attached breathing-circuit accessories, external heating systems, sensors, connections, setup, or environmental conditions.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Appropriate Respiratory Support
Do not troubleshoot a temperature-control or humidification problem while a patient depends on the affected setup. If an attached humidification or warming accessory is unreliable, use an approved alternative setup according to clinical requirements.
Expected outcome: Patient ventilation and required airway conditioning are maintained independently of the affected equipment.
2. Confirm Which Device Is Producing the Complaint
Determine whether the reported problem originates from the Flow-c itself or from a separate humidifier, heated circuit, temperature probe, or other accessory used with the anesthesia breathing system. Record the exact message and affected component.
Expected outcome: The problem is correctly assigned to the anesthesia machine or to an attached accessory rather than being misidentified.
3. Inspect the Breathing Circuit and Accessories
Check circuit tubing, adapters, filters, water traps, and any humidification or warming components for correct assembly, secure connections, excessive condensation, kinks, or obvious damage.
Expected outcome: External components are assembled correctly and do not create an apparent temperature or humidification problem.
4. Verify Accessory Power and Connections
For separately powered approved accessories, verify their AC or approved power connection, cable seating, and visible status indicators. Inspect cables and connectors for damage.
Expected outcome: The accessory receives reliable power and its external connections are intact.
5. Inspect Temperature Sensors or Probes When Present
If the setup includes an external temperature sensor or probe, verify correct placement, connection, orientation, and physical condition according to the accessory's approved configuration.
Expected outcome: Temperature sensing is correctly positioned and connected.
6. Check Environmental and Condensation Conditions
Look for unusually cold rooms, recent equipment relocation, excessive condensation, pooled water, blocked tubing, or other environmental conditions that could affect temperature or humidity performance.
Expected outcome: The system is assessed under normal environmental conditions without external moisture-related interference.
7. Use Known-Good Approved Accessories When Appropriate
Substitute a known-good circuit accessory, sensor, cable, or separate humidification component when available and permitted. Do not substitute unapproved components merely to clear an alarm.
Expected outcome: The problem follows a defective external accessory or remains associated with the primary equipment.
8. Perform Final Functional Verification
After correction, verify breathing-system integrity, ventilation, associated temperature or humidification function, alarms, and required anesthesia-machine pre-use checks.
Expected outcome: The complete setup operates normally without unresolved temperature, humidification, or ventilation concerns.
If the Problem Persists
If the complaint has been confirmed to involve the Getinge Flow-c rather than an external humidification accessory, and circuit setup, accessory power, sensing connections, condensation, and environmental causes have been ruled out, a service-level sensing, interface, configuration, or control problem may be present.
Remove affected equipment from service, label it Out of Service, and send it for repair or bench evaluation. Evaluate the Flow-c and any connected accessory using the appropriate manufacturer's documentation and approved test equipment. Internal electrical or control-system repairs should be performed only by qualified personnel.
The complete anesthesia breathing setup must pass appropriate functional testing before being returned to use. Correctly identifying whether the anesthesia machine or an accessory owns the fault is an important part of proper troubleshooting.
Clinical Use Tip
Determine whether a humidification or temperature complaint actually belongs to an external breathing-circuit accessory before removing the anesthesia machine itself from service.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"OR staff reported inadequate warming from the breathing-circuit setup connected to the Getinge Flow-c."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the external temperature-probe connector on the approved heated-circuit accessory was not fully seated."
Resolution
What action was taken.
Example:
"Clinical Engineering secured the probe connection, verified normal accessory operation, and confirmed the Flow-c breathing system and ventilation checks passed."
Helpful Details to Include (If Known)
- Exact message or symptom
- Whether the Flow-c or an external accessory generated the fault
- Circuit configuration
- Accessory power status
- Sensor or probe placement
- Cable and connector condition
- Condensation or pooled water observed
- Environmental conditions
- Known-good substitution result
- Final breathing-system test result
- Final device status
Final Thought
Temperature and humidification complaints often involve the complete breathing setup rather than the anesthesia machine alone. Protect the patient, identify the responsible device, verify external accessories and sensing first, then escalate only after those causes are ruled out.
That is successful troubleshooting.
