What This Guide Helps With
Troubleshoots missing network or central monitoring communication caused by host connection, network path, configuration, infrastructure, or communication-state issues.
Step-by-Step Troubleshooting
1. Protect the Patient and Provide Alternate Alarm Surveillance
If CARESCAPE ONE patient data or alarms are not reaching the intended central monitoring location, notify clinical staff and establish an alternate verified alarm-surveillance method.
Do not assume central staff can see or hear alarms until communication is explicitly confirmed.
Expected outcome: Patient monitoring and alarm awareness remain continuous despite the communication failure.
2. Confirm the Scope of the Failure
Determine:
- Whether local monitoring remains normal.
- Whether the host monitor receives CARESCAPE ONE parameters.
- Whether only central station communication is missing.
- Whether one bed, room, host, or multiple devices are affected.
- Whether the problem is intermittent or continuous.
- Whether a recent move, network change, equipment replacement, or configuration change occurred.
Expected outcome: The failure is localized to the CARESCAPE ONE-to-host path, host-to-network path, or broader infrastructure.
3. Verify Local CARESCAPE ONE and Host Operation
Confirm the CARESCAPE ONE is functioning locally and, when used through a host monitor, verify that the host receives expected parameters.
A central communication complaint should not be treated as a network problem until the local host communication path is verified.
Expected outcome: Local monitoring and host communication are known to be functional, or the upstream problem is identified and corrected.
4. Inspect Accessible Network Connections
Inspect accessible network cables, connectors, wall ports, docking connections, and associated external communication hardware used by the host system.
Look for loose cables, damaged latches, disconnected patch cables, or obvious physical damage.
Expected outcome: External network connections are secure. If reconnecting an external cable restores central communication, verify the complete path and stop troubleshooting.
5. Check Network Link or Communication Indicators
Observe available network or communication indicators on the host or associated equipment without entering restricted service menus.
Compare with a nearby known-good monitoring location when useful.
Expected outcome: The host appears connected to the network infrastructure. Absent connectivity isolated to one physical port or cable should be escalated to the appropriate CE/IT support path.
6. Compare With a Known-Good Network Location
If permitted and practical, connect the compatible host monitoring setup to a known-good network connection or compare another known-good monitor on the suspect port.
Coordinate with IT or clinical systems teams when moving or changing network connections could affect production systems.
Expected outcome: The failure follows either the equipment or network location, narrowing the fault.
7. Verify Bed and Central Station Association
Confirm that the patient/bed is associated with the intended monitoring location using approved operational configuration.
Check for obvious mismatches after room changes, monitor swaps, or host replacements.
Do not alter protected network addressing or service configuration without authorization.
Expected outcome: The monitor is associated with the intended bed and central monitoring destination. If correcting an approved assignment restores communication, verify alarms and stop.
8. Determine Whether the Problem Is Infrastructure-Wide
Check whether nearby monitors or beds are also missing from central monitoring.
Multiple affected systems may indicate a network switch, server, central station, VLAN, interface, or other infrastructure problem rather than a CARESCAPE ONE failure.
Expected outcome: Device-specific problems are separated from infrastructure-wide events and routed to the appropriate support team.
9. Verify the Complete Communication and Alarm Path
After restoration, verify:
- Local CARESCAPE ONE parameters.
- Host monitor parameters.
- Central station patient identification.
- Waveform and numeric updates.
- Alarm transmission and annunciation at the intended central station.
- Stable communication over an appropriate observation period.
Expected outcome: The complete bedside-to-central monitoring path functions correctly. Troubleshooting can stop.
10. Escalate Persistent Network Communication Failure
If local operation is normal but central communication remains unavailable after checking external connections, approved assignments, and known-good comparisons, stop external troubleshooting.
Expected outcome: The issue is escalated to qualified Clinical Engineering, IT/network, clinical systems, or manufacturer support according to the isolated failure domain.
If the Problem Persists
Common external causes have been ruled out. The remaining issue may involve host network hardware, network infrastructure, switch or port configuration, monitoring network services, software compatibility, protected configuration, central station services, or another service-level fault.
The affected system should be:
- Removed from service when reliable central monitoring is required and cannot otherwise be provided.
- Labeled Out of Service when appropriate.
- Sent for repair or bench evaluation if a device-level fault is suspected.
- Evaluated using appropriate GE Healthcare documentation and approved network/test tools.
- Repaired or configured only by qualified CE, IT, clinical systems, or manufacturer personnel.
Before return to normal clinical use, verify the full path from bedside measurement through host display to the intended central station, including alarm delivery.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Central monitoring is a complete communication path, not just a network icon; verify the actual patient waveform, numerics, and alarms at the receiving station.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported CARESCAPE ONE parameters were visible at the bedside but the patient was not appearing at the central station."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the host monitor network cable was partially disconnected from the bedside network connection."
Resolution
What action was taken.
Example:
"The network cable was securely reconnected, and patient identification, waveforms, numerics, and alarm communication were verified at the central station."
Helpful Details to Include (If Known)
- Local CARESCAPE ONE status.
- Host monitor model and status.
- Whether the host received CARESCAPE ONE data.
- Central station affected.
- Network cable and port condition.
- Link or communication indicators.
- Other rooms or beds affected.
- Known-good port or monitor comparison.
- Recent equipment or network changes.
- Final waveform and alarm verification at central.
Final Thought
Network troubleshooting should first prove the local monitor and host path, then work outward through physical connections, approved configuration, and infrastructure. Never return a centrally monitored patient to normal workflow until the receiving station and alarm path are explicitly verified.
That is successful troubleshooting.
