What This Guide Helps With
Troubleshooting missing ECG waveforms or vital sign parameters at the central station caused by patient connection, monitor, network, layout, or configuration issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
A missing ECG waveform or missing vital sign parameter at the central station may affect alarm visibility and remote monitoring.
Action:
- Confirm the patient is being monitored safely at the bedside.
- Verify clinical staff can view the needed ECG waveform, SpO2, NIBP, IBP, temperature, respiration, or other parameters directly on the bedside monitor.
- If central monitoring is not reliable, instruct staff to monitor the patient locally until the issue is corrected.
Expected outcome: Patient monitoring continues safely while the central display problem is investigated.
Why it matters: The central station is a secondary display point. Do not assume the patient is unmonitored until the bedside monitor has been checked.
Verify the Reported Missing Parameter
Confirm exactly what is missing.
Action:
- Ask staff what is missing: ECG waveform, heart rate, SpO2, NIBP, IBP, respiration, temperature, CO2, alarm data, one patient sector, or multiple patient sectors.
- Confirm whether the issue affects one patient, one bed, or multiple beds.
Expected outcome: The issue is narrowed to a specific parameter, patient sector, bedside monitor, or central station display problem.
If only one patient is affected, continue with bedside and patient-sector checks.
If multiple patients are affected, suspect a central station, network, switch, interface, or system-level issue.
Check the Bedside Monitor First
Go to the bedside monitor and verify whether the missing parameter is present locally.
Action:
- Confirm the waveform or vital sign parameter appears correctly on the bedside monitor.
- Check that the monitor is not paused, in standby, discharged, or assigned to the wrong patient.
- Verify the bedside monitor is not showing technical alarms related to leads, sensors, modules, or cables.
Expected outcome: The bedside monitor displays the patient data normally.
If the data is missing at the bedside monitor too, troubleshoot the bedside monitor, patient cable, module, or accessory first.
If the data is present at the bedside but missing at the central station, continue.
Check Patient Cable, Leads, Sensors, and Modules
Missing ECG or parameter data may be caused by a patient-side accessory problem.
Action:
- For ECG: check that ECG leads are connected to the patient, inspect lead wires for damage, confirm electrodes are fresh, properly placed, and making good skin contact, and swap the ECG trunk cable or lead set if available.
- For SpO2: check sensor placement, inspect the sensor and cable, and try a known-good sensor.
- For IBP, CO2, temperature, or other modules: confirm the module is seated correctly, verify the correct cable, transducer, or sensor is connected, and check for bedside technical alarms.
Expected outcome: The parameter appears correctly at the bedside and then updates at the central station.
If this resolves the issue, confirm central display recovery and stop.
Confirm the Bedside Monitor Is Connected to the Network
The central station depends on communication from the bedside monitor.
Action:
- Check the bedside monitor network connection.
- Verify the Ethernet cable is connected securely if using wired communication.
- If using wireless communication, confirm the monitor has network connectivity and is not outside expected coverage.
- Look for network disconnected, offline, communication lost, or central station connection messages.
Expected outcome: The bedside monitor is connected and communicating with the monitoring network.
If the bedside monitor is offline, correct the network connection or escalate to network support if the connection cannot be restored.
Verify the Correct Bed Is Assigned at the Central Station
A patient may appear to be missing parameters if the wrong bed, room, or patient sector is selected.
Action:
- At the BeneVision central station, confirm the correct bed label, room number, patient name, and monitor assignment.
- Check whether the patient was recently transferred, admitted, discharged, or moved to another monitor.
- Verify that the patient sector is not assigned to the wrong bedside monitor.
Expected outcome: The central station sector matches the correct patient and bedside monitor.
If the wrong bed is assigned, correct the assignment according to site workflow and confirm the waveform or parameters return.
Check the Central Station Display Layout
Sometimes parameters are available but hidden due to screen layout, patient sector size, or display configuration.
Action:
- Open the patient sector or patient detail view.
- Check whether the missing waveform or parameter appears in another view.
- Verify the waveform list, parameter display settings, and screen layout.
- Confirm the parameter has not been removed from the displayed view.
Expected outcome: The missing waveform or parameter is visible after selecting the correct view or layout.
If the parameter is only hidden from the layout, restore the expected display configuration and stop.
Check for Alarm Pause, Standby, Discharge, or Monitoring Mode Changes
Certain patient or monitor states can affect what appears at the central station.
Action:
- Confirm the bedside monitor is not in standby.
- Verify the patient has not been discharged from the central station.
- Check whether alarms are paused, monitoring is suspended, or the patient sector has been intentionally silenced or minimized.
- Confirm the monitor is in the correct clinical monitoring mode for the patient.
Expected outcome: The bedside monitor and central station are both in active monitoring status.
If the patient was in standby or discharged, restore monitoring according to clinical workflow and confirm parameter display.
Refresh the Patient Sector or Reconnect the Bed
If the bedside monitor is working and network communication appears normal, the central station may need the patient sector refreshed.
Action:
- Close and reopen the patient detail view if allowed by site workflow.
- Re-select the patient sector.
- If permitted by local procedure, remove and re-add the bed assignment.
- Confirm whether data begins updating again.
Expected outcome: The patient sector refreshes and the ECG waveform or vital sign parameters reappear.
If the issue clears after reassignment or refresh, monitor briefly to confirm the data remains stable.
Compare With Another Central Station or Viewpoint
Determine whether the issue is local to one central display or affects the monitoring network.
Action:
- Check whether the same patient data appears on another central station, remote viewer, or alternate monitoring display if available.
- Compare the affected patient sector against other beds on the same central station.
Expected outcome: The scope of failure is identified.
If the data appears elsewhere, suspect a local central station display, layout, or software issue.
If the data is missing everywhere except the bedside monitor, suspect communication, configuration, or network routing.
Check for Central Station Software Freeze or Display Issue
A frozen central station may show stale or incomplete patient data.
Action:
- Look for frozen waveforms, unchanged timestamps, missing updates, locked mouse/keyboard response, or delayed display refresh.
- Confirm whether other patient sectors are updating normally.
- Do not reboot or restart the central station without following hospital policy and ensuring patient monitoring coverage.
Expected outcome: The central station is confirmed to be actively updating.
If the central station is frozen or not updating, escalate according to site procedure and ensure patients are monitored locally or on alternate central monitoring.
Inspect External Network Hardware
If multiple beds or multiple parameters are affected, check external network equipment before assuming software failure.
Action:
- Inspect visible network cables at the central station.
- Check that the central station computer, display, keyboard, and mouse are powered and connected.
- Look for disconnected patch cables, damaged cords, unplugged network drops, or network switch power issues in accessible areas.
- Do not make unauthorized network changes.
Expected outcome: Obvious external communication issues are identified or ruled out.
If a network switch, VLAN, port, or hospital network issue is suspected, escalate to Clinical Engineering network support or IT.
Confirm Whether a Recent Change Occurred
Recent changes often explain missing waveforms or parameters.
Action:
- Ask whether the issue started after patient transfer, bedside monitor replacement, module swap, cable replacement, network maintenance, central station restart, software update, or room move.
Expected outcome: The likely trigger is identified.
If the issue follows a monitor, module, or cable, evaluate that item.
If the issue follows a room or network drop, escalate for network or configuration review.
Document and Escalate When Configuration or System Support Is Needed
If the bedside monitor shows data correctly but the central station does not, and basic assignment, layout, and connection checks do not correct the problem, avoid deep system changes unless authorized.
Action:
- Remove reliance on the affected central station view.
- Notify clinical leadership or charge staff.
- Escalate to Clinical Engineering, Mindray support, or IT/network support depending on the suspected cause.
- Include bed number, patient sector, missing parameter, bedside monitor status, and whether other central stations show the data.
Expected outcome: The issue is escalated with enough detail for repair, configuration review, or network troubleshooting.
If the Problem Persists
If ECG waveforms or vital sign parameters are still missing after bedside accessories, monitor status, bed assignment, display layout, and external network checks have been ruled out, the problem is likely related to system configuration, software communication, central station hardware, or network routing.
The affected central monitoring station or patient sector should be removed from clinical reliance until verified, labeled or communicated as not reliable for that patient view, and sent for bench evaluation, system review, vendor support, or IT/network escalation as appropriate.
Knowing when to stop is proper troubleshooting. Do not continue making central station configuration changes without the correct access, approval, and backup monitoring plan.
Clinical Use Tip
Do not troubleshoot a missing ECG waveform or vital sign parameter as a display-only problem until bedside monitoring is confirmed. If the patient requires continuous monitoring, clinical staff should verify the patient directly at the bedside or move monitoring to another reliable device before extended troubleshooting continues.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the BeneVision Central Monitoring System was not displaying the ECG waveform for Bed 12, although the patient remained connected to the bedside monitor."
Cause
What was observed during troubleshooting.
Example:
"Bedside ECG was present, but the central station patient sector was assigned to the wrong bed after a patient transfer."
Resolution
What action was taken.
Example:
"Corrected the bed assignment at the central station, verified ECG waveform and heart rate returned, and confirmed the patient sector updated normally."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Bed or room number affected

Final Thought
Missing ECG waveforms or vital sign parameters should be approached logically: protect the patient first, verify bedside monitoring, check accessories and assignments, then evaluate central display and network communication. Good documentation helps separate patient-side issues from central station, configuration, or network problems.
That is successful troubleshooting.
