Manufacturer Recommendation / AEM Status

Manufacturer-Listed PM Frequency

The manufacturer-listed planned maintenance interval is every two years after installation.

The planned maintenance check includes:

GE states that the planned maintenance check is intended to verify that the monitor remains safe to use and maintains its performance characteristics.

Scope Clarification

This procedure is intentionally focused on the CARESCAPE Canvas monitor itself:

It does not include detailed PM testing of:

The manual states that planned and corrective maintenance procedures for connected devices are located in their respective service manuals. The complete patient-monitoring system, including connected devices, must receive all applicable planned maintenance.

This monitor-focused procedure does not eliminate separate PM requirements for attached acquisition devices, frames, secondary displays, or accessories.

Manufacturer-Listed Replacement Items

No routine filter, battery, calibration component, or scheduled replacement part is listed for the Canvas monitor itself in the provided planned maintenance procedure.

Post-Repair Safety Inspection

After corrective maintenance in which the monitor enclosure is opened, the manufacturer lists:

After detaching or replacing only the mounting plate, the manual lists a visual inspection of cable strain relief and confirmation that the monitor starts normally.

After replacement of the mains fuses, the manual lists confirmation that the monitor starts normally.

AEM Status

If a facility performs this PM at a different interval or changes the listed activities, the change should be handled under the facility’s approved AEM program, risk assessment, maintenance history, and applicable regulatory requirements.

What This PM Procedure Covers

Required Tools and Equipment

No patient simulator is required for this monitor-only procedure. Measurement verification belongs to the applicable acquisition-module or CARESCAPE ONE procedure.

Step-by-Step PM Procedure

1. Identify the Monitor and Review Service History

Action

Record:

Confirm that the PM is being completed at the manufacturer-listed two-year interval unless an approved AEM interval applies.

Expected Outcome

The monitor is correctly identified and the maintenance interval is documented.

2. Remove the Monitor From Clinical Use

Action

Confirm that the monitor is not actively supporting a patient.

Discharge or end the patient case according to facility procedure before restarting, disconnecting, or testing the monitor.

Disconnect acquisition modules and peripheral devices as needed for the monitor electrical safety test. Preserve configuration and network connections needed for later functional testing.

Expected Outcome

The monitor can be safely tested without interrupting patient monitoring or altering active patient records.

3. Inspect Labels, Enclosure, and Mounting

Action

Inspect the monitor for:

The manufacturer’s visual inspection requires that labeling remain readable, that the monitor have no visible damage, and that the monitor be properly mounted.

Expected Outcome

The enclosure, labels, display, controls, and mounting system are intact and secure.

Remove From Service When

4. Inspect the Power Cord and Monitor Connectors

Action

Inspect the power cord and plug for:

Inspect applicable monitor connections:

Verify that connectors are not bent, loose, contaminated, or physically damaged.

The manual requires cables between the monitor and connected equipment to be intact, properly connected, and secured to the correct connectors.

Expected Outcome

The power cord, cable strain relief, and monitor connectors are intact and serviceable.

5. Inspect Cooling and Ventilation

Action

Check that the rear and lower ventilation openings are:

Clean exterior surfaces and ventilation openings according to the applicable GE cleaning and disinfection instructions. Do not allow liquid to enter the monitor.

Expected Outcome

Air can circulate freely through the monitor and there are no signs of overheating or contamination.

6. Perform the Startup Check

Action

With the monitor initially off:

  1. Connect the monitor to AC power.
  2. Confirm the AC-power indicator illuminates.
  3. Turn the monitor on.
  4. Observe the complete startup sequence.

Verify that:

These are manufacturer-listed startup checks.

Expected Outcome

The monitor completes startup normally, the alarm-light segments illuminate, the audible startup indication is present, and no system fault remains.

Remove From Service When

7. Check Display Picture Quality

Action

Inspect the integrated display with the normal monitoring screen and open menus.

Confirm that:

The manufacturer-listed display check requires readable text, clear images, and adequate brightness.

Expected Outcome

The display is stable, clear, and readable across the usable screen area.

8. Test the Touchscreen

Action

Touch multiple areas of the screen, including:

Confirm that the selected menu opens and that selections correspond to the location touched.

Return to the normal monitoring screen after testing.

The manual specifically instructs the technician to touch an active parameter window or main-menu key and verify that the related menu opens.

Expected Outcome

The touchscreen responds accurately without dead zones, unintended selections, or delayed operation.

9. Verify Host Information and Licenses

Action

Log in to the CARESCAPE Service interface.

Open Information and verify:

The manual includes host serial number, active software version, and host-license verification as part of the functional check.

Do not perform detailed verification of connected PDMs, CARESCAPE ONE devices, E-modules, frames, or CARESCAPE Parameters under this monitor-only procedure. Those items require their own service procedures.

Expected Outcome

The host identity, active software, and installed licenses agree with the expected monitor configuration.

10. Verify Wired Network Communication

Action

When the monitor is normally connected to the CARESCAPE network:

Use a temporary test patient or facility-approved test workflow where necessary. Do not transmit simulated information under a real patient record.

Expected Outcome

The monitor communicates reliably with the configured CARESCAPE MC Network and central station.

Facility-Policy Consideration

Network and central-station verification may require coordination with clinical staff, monitoring technicians, or IT. Document when network testing cannot be completed and why.

11. Check Applicable Monitor Accessories

Action

Only test accessories that are assigned to the monitor and included under the facility’s PM scope.

Possible checks include:

These items are listed in the manual’s functional checkout section, but their use depends on the installed configuration.

Expected Outcome

Each installed monitor accessory is recognized and operates normally.

Electrical Safety Testing

The CARESCAPE Canvas monitor is Class I equipment. Planned maintenance includes electrical safety testing.

For the monitor-only PM, test the monitor separately from connected acquisition equipment.

Before testing:

The manual provides separate procedures for ground integrity, earth leakage, and touch current.

Ground Resistance

For equipment tested with its power cord, the manufacturer’s acceptance criterion is ≤ 0.2 Ω between the protective-ground pin of the mains plug and accessible protectively grounded metal.

The manual lists ≤ 0.1 Ω for equipment tested without a power-supply cord.

Ground resistance measured in ohms, expected ≤ 0.2 Ω with the power cord, or facility/NFPA 99 criteria if different:

Result =

While measuring, flex the power cord along its length and verify that the reading does not fluctuate.

Pass / Fail =

Earth Leakage Current

Perform earth leakage testing in:

The manufacturer-listed limits are:

Earth leakage measured in microamps or milliamps:

Normal polarity, normal condition =

Normal polarity, neutral open =

Reversed polarity, neutral open =

Reversed polarity, normal condition =

Pass / Fail =

Touch/Chassis Leakage

The manual lists touch-current testing in normal and reversed polarity with applicable normal and single-fault conditions. For the Canvas 1000 monitor, the manual notes that normal-condition touch-current testing is not necessary because the accessible connectors are connected to protective earth.

Because the complete touch-current acceptance values were not clearly stated in the available extracted section, do not substitute a generic leakage limit.

Touch/chassis leakage measured in microamps:

Facility or manufacturer test condition used =

Facility limit used =

Result =

Pass / Fail =

Patient source and patient sink leakage tests belong to the connected acquisition modules and are not included in this monitor-only procedure.

Pass / Fail Criteria
