What This Guide Helps With
Troubleshoots applicable Volista audible or visual alert behavior caused by an unresolved condition, control setting, obstruction, environment, or service-level fault.
Step-by-Step Troubleshooting
1. Protect the Patient and Do Not Ignore an Active Alert
If an alert indicates that lighting reliability may be compromised, establish alternate verified surgical illumination before troubleshooting. Never silence or bypass a warning without identifying why it is present.
Expected outcome: Patient care remains protected and the alert can be investigated safely.
2. Confirm That an Audible Alarm Function Applies
Identify the exact audible or visual indication being reported and verify that the installed Volista configuration includes that alert function. Do not assume that every Volista installation uses the same alarm or audio features.
Expected outcome: The reported alert or audio function is confirmed as applicable to the installation.
3. Record the Exact Indication
Document the exact visible message, indicator, sound pattern, or condition reported by staff. Determine whether the alert is continuous, intermittent, appears at startup, or occurs during a specific action.
Expected outcome: The symptom is captured without inventing an error interpretation.
4. Check for an Active External Cause
Inspect the system for obvious conditions associated with the alert, such as loss of supply power, disconnected accessory, incomplete startup, or another externally visible abnormal state.
Expected outcome: Any clear external condition is corrected. If the indication clears and normal function is verified, troubleshooting can stop.
5. Verify Normal Control Settings
Check only normal operator-accessible settings associated with the applicable indication or audio function. Ensure that a permitted volume or mute control, if present on the installed configuration, has not been unintentionally changed.
Expected outcome: Normal settings are appropriate. Do not enter restricted menus to alter alarm behavior.
6. Inspect the Audible-Output Area
Where an audible output device is externally identifiable, inspect for obstruction, contamination, physical damage, coverings, or room conditions that could make the sound difficult to hear. Do not open the control housing.
Expected outcome: No external obstruction explains weak audio.
7. Compare the Alert From Normal Working Positions
Evaluate whether the alert is audible from the intended staff location under normal room conditions. If permitted, compare with another equivalent installation rather than assuming subjective loudness indicates failure.
Expected outcome: The audio function is either demonstrated as normally perceivable or confirmed as abnormal.
8. Perform an Approved Functional Test
If manufacturer documentation provides an applicable external alarm or indicator test, perform it using the documented procedure. Do not create an undocumented test or manipulate internal alarm circuits.
Expected outcome: The applicable alert activates and clears correctly. If so, and the original condition has been corrected, troubleshooting can stop.
9. Escalate Persistent or Missing Alert Behavior
If an alert persists after its triggering condition has been corrected, or required audible notification cannot be verified, remove the affected function from service and escalate.
Expected outcome: A system with unreliable required alerting is not returned to unrestricted clinical use.
If the Problem Persists
Common external conditions, normal settings, obstruction, and environmental causes have been ruled out. The remaining problem may involve alert logic, internal audio hardware, control electronics, software, configuration, or another service-level condition.
Remove the affected system from service when the alert function is required for safe operation, label it Out of Service, and arrange qualified evaluation using current Getinge documentation and approved test equipment. Internal repairs or configuration changes should be performed only by qualified personnel.
Before return to service, verify correct initiation and clearing of applicable alerts and reliable normal light operation. Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Never treat a persistent warning as a nuisance condition; first confirm that the underlying reason for the indication has actually been resolved.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"OR staff reported that a Volista audible indication was difficult to hear during normal use."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the externally accessible audio opening partially obstructed by residue from prior cleaning."
Resolution
What action was taken.
Example:
"The obstruction was removed using the approved cleaning method, applicable alert operation was verified, and the system was returned to service."
Helpful Details to Include (If Known)
- Exact audible or visual indication
- When the alert occurs
- Applicable system configuration
- Power status
- Associated accessory status
- Normal settings observed
- Obstruction or contamination
- Comparison with equivalent equipment
- Functional test result
- Final device status
Final Thought
Treat abnormal alerting as a safety issue, identify the exact condition before attempting correction, verify normal alert behavior afterward, and escalate when required notification cannot be proven reliable.
That is successful troubleshooting.
