AEM note

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

Because this is a defibrillator, shortening the PM too aggressively or skipping defibrillator output, sync, leakage, pacing, or option-specific tests should be treated as a high-risk AEM decision, not a casual checklist edit.

Step-by-Step PM Procedure

1. Confirm Unit Identity and Configuration

Action: Record the serial number, location, installed options, and whether the unit includes pacing, SpO₂, EtCO₂, and/or NIBP.

Expected outcome: Unit configuration is known before testing begins.

Why it matters: Several manufacturer-listed tests are option-dependent. Do not mark missing options as failed.

2. Perform Physical Inspection

Action: Inspect housing, handle, recorder door, input connectors, front panel, keypad, paddle latches, paddles, cables, strain reliefs, and battery seating.

Expected outcome: Unit is clean, intact, undamaged, and free of excessive wear. Cables should have no cracks, cuts, exposed wires, or damaged strain reliefs.

Remove from service if: Cracked housing, damaged connectors, exposed wires, failed paddle latches, damaged paddles, battery seating issue, or any condition that could affect safe clinical use.

3. Front Panel Button and Recorder Check

Action: Power the unit on in Monitor / ON mode. Verify startup tones, lead selection, ECG size changes, alarm suspend function, recorder operation, check-recorder message with door open, AC power LED, battery LED, energy selection, charge function, and shock button operation.

Expected outcome: Controls respond correctly, recorder prints correctly, messages clear properly, and energy selection/charge/discharge functions operate as expected.

4. ECG Lead Test

Action: Using the defibrillator analyzer and applicable ECG cables, verify 3-lead and/or 5-lead ECG operation. Disconnect and reconnect each lead to verify lead-off detection.

Expected outcome: ECG lead-off messages display and clear appropriately within expected behavior.

5. Optional Power Supply / Charger Test

Action: Perform only if included in facility PM workflow. Follow the manual setup using DC power supply, resistors, DMM, and battery/charger fixture.

Expected outcomes listed in the manual include:

• Unit should not power on at 7 V.
• Unit should power on at 10.8 V with no LOW BATTERY message.
• LOW BATTERY should display at 10.5 V within 30 seconds.
• REPLACE BATTERY should display at 10.2 V within 30 seconds.
• System current should be within manual-listed limits.
• Charger voltage should meet manual-listed ranges.
• 200 J charge time should be 3–10 seconds during charger test.

6. Leakage Current Test

Action: Perform leakage current testing using the electrical safety analyzer / leakage tester per the tester manufacturer’s instructions. Repeat with applicable accessories: OneStep cable, external paddles, internal paddles, and anterior/posterior paddles when applicable.

Manufacturer-listed maximum leakage acceptance limits:

• Lead ECG: 10 µA normal condition, 50 µA single fault condition
• Hands-free electrodes / paddles / MFE: 10 µA normal condition, 100 µA single fault condition
• Earth: 500 µA normal condition, 1000 µA single fault condition

The manual notes the single fault condition as AC mains on applied part.

7. Paddles Test

Action: If paddles are used, verify paddle energy select buttons, recorder button, charge button, individual shock-button behavior, and dual-button discharge.

Expected outcome: Energy selection changes correctly, recorder starts/stops, unit charges to selected energy, individual paddle shock buttons do not discharge alone, and both shock buttons together discharge properly.

8. Heart Rate Display Test

Action: Connect ECG cable to analyzer. Set simulated rhythm to 120 BPM.

Expected outcome: Heart rate displays 120 ± 2 BPM.

9. Calibration Pulse / Strip Chart Test

Action: Activate the calibration signal and print strip chart.

Expected outcome: Strip chart displays a 300 ppm signal with amplitude 10 mm ± 1 mm.

10. Notch Filter Test

Action: Use the analyzer to input 50 Hz or 60 Hz sine wave depending on unit configuration.

Expected outcome: Waveform amplitude on strip chart is less than 1.5 mm.

11. Heart Rate Alarm Test

Action: Verify alarm menu navigation, enable/disable function, lead-off alarm, high heart rate alarm, alarm suspend, and alarm disable behavior.

Expected outcome: Alarm states, bell symbol behavior, highlighted heart rate values, and alarm tones respond as expected.

12. Defibrillator Self-Test

Action: Perform the 30 J self-test using the OneStep cable and test port as described by the manual.

Expected outcome: Unit displays 30J TEST OK. Printed strip should indicate 30 JOULES TEST OK, with test current and impedance within the manual-listed expected range.

Remove from service if: Self-test fails, unit does not charge/discharge correctly, or unexpected defib fault appears.

13. Synchronized Cardioversion Test

Action: Connect the OneStep cable to the defibrillator analyzer using the adapter. Input 1 mV ECG at 60 BPM. Enable sync and deliver synchronized shock.

Expected outcome: Sync markers appear over R-waves. Sync delay is less than 60 ms.

14. Remote Sync Cardioversion Test — If Applicable

Action: If the unit is configured for remote sync, test the complete system with the remote monitor connected to the Sync In/Marker Out connector.

Expected outcome: Remote sync displays properly and sync delay is less than 60 ms.

15. Shock Output Test

Action: Using a defibrillator analyzer and fully charged battery, test output at manufacturer-listed energy settings.

Expected outcomes:

• 5 J selected: delivers 3–7 J
• 50 J selected: delivers 46–62 J
• 100 J selected: delivers 93–125 J

16. Summary Report Test

Action: Erase prior report data if appropriate, deliver a shock into analyzer, add a code marker, power cycle, and print the summary report.

Expected outcome: Summary report prints with correct date, time, shock delivered, and code marker event.

17. Advisory Message Test — Manual / Advisory Units

Action: Using analyzer rhythm simulations, verify advisory behavior with VF and NSR.

Expected outcome: VF results in shock-advised sequence. NSR results in no-shock-advised behavior.

18. Pacer Test — If Installed

Action: Using external pacer analyzer or equivalent, verify pad contact messages, output accuracy, rate accuracy, pulse width, demand behavior, asynchronous pacing, recorder markers, and 4:1 behavior.

Expected outcomes include:

21. Barometric Pressure Calibration Check — If EtCO₂ Installed

Action: Enter EtCO₂ calibration screen and compare/set barometric pressure using local barometric pressure converted to mmHg if needed.

Expected outcome: Barometric pressure value is stored and calibration screen returns normally.

22. CO₂ Accuracy Check — If EtCO₂ Installed

Action: Use calibration gas and regulator. Set gas temperature and gas balance as required.

Expected outcome: With 5% CO₂ calibration gas, displayed value is 5% ± 0.2%.

23. NIBP Volume Leak Test — If Installed

Action: Use NIBP simulator. Enter NIBP service mode, close valves, apply 200 mmHg, and start volume leak test within 30 seconds.

Expected outcome:

• Volume leak reading <55 = pass.
• Volume leak reading >56 = fail.
• No volume leak reading but stable pressure at or above 200 mmHg = pass.
• If using Fluke Biomedical CuffLink, manual notes <10 as pass and >10 as fail.

24. NIBP Transducer Calibration Test — If Installed

Expected outcome:

• 0 mmHg calibration field displays PASS.
• 250 mmHg calibration field displays PASS.
• Verification pressure reads within ±3 mmHg of simulator pressure.

The manual warns that NIBP transducer calibration can affect clinical NIBP readings and should be followed by the NIBP Monitor Test.
