Step-by-Step PM Procedure

1. Remove the Ventilator From Clinical Use

Confirm that no patient is connected.

Do not enter Diagnostic mode or perform PM testing while the ventilator is supporting a patient. Provide an alternate means of ventilation according to facility procedure.

Expected outcome: The ventilator is safely available for controlled service testing.

2. Review Equipment History

Review:

• Previous PM and repair history
• Open recalls or field corrections
• Reported intermittent faults
• Battery replacement history
• Software version
• Repeat diagnostic codes

Do not clear diagnostic information before relevant findings have been recorded.

Expected outcome: Outstanding safety or repair issues are identified before PM begins.

3. Clean and Inspect the Exterior

Power the ventilator down and disconnect AC power.

Clean the exterior and touchscreen using only agents approved in the service manual. Apply solution to a cloth or wipe; do not spray or drip liquid directly onto the ventilator.

Inspect:

• Enclosure and touchscreen
• Navigation ring and controls
• Power switch and indicators
• AC inlet and power cord
• Gas outlet
• Proximal-pressure port
• Oxygen inlet and fitting
• Alarm-speaker openings
• Fan intake and air inlet
• Labels and identification
• Stand and mounting hardware when included in the PM scope

Expected outcome: Exterior surfaces are clean, dry, intact, and free of conditions that could affect safe operation.

4. Record Ventilator Information

Enter Diagnostic mode and record:

• Serial number
• Installed software options
• Operational software version
• PIC software version
• PMC PLD version
• Total operating hours
• Hours since last PM
• Battery lot ID
• Battery manufacture date
• Relevant PCBA information when required by facility procedure

Generate and save a diagnostic report before clearing any logs.

Expected outcome: Configuration, operating history, and diagnostic information are documented.

5. Open and Inspect the Ventilator

Disconnect all power, including the internal battery as directed by the service procedure.

Remove the top cover and required shielding.

Using an ESD-safe vacuum:

• Remove accumulated dust and debris.
• Inspect electrical connections.
• Inspect pneumatic tubing and connections.
• Look for looseness, contamination, fluid intrusion, overheating, damaged insulation, corrosion, or deteriorated tubing.

Expected outcome: The interior is clean and connections appear secure and undamaged.

6. Complete Manufacturer-Listed Filter Maintenance

Air Inlet Filter

Replace the air inlet filter as part of the annual PM-kit installation.

The separate manufacturer-listed inspection interval is every 250 operating hours, with more frequent inspection in dusty environments.

Cooling Fan Filter

Replace the cooling fan filter during annual PM.

The separate manufacturer-listed inspection interval is monthly. When performing interim maintenance, a dirty reusable filter may be washed or rinsed and must dry completely before reinstallation.

Oxygen Inlet Filter

Remove the oxygen-filter cap and inspect the oxygen inlet filter for:

• Contamination
• Debris
• Damage
• Proper installation

Do not automatically replace the oxygen inlet filter unless its condition, the PM kit, or current Philips instructions call for replacement.

Expected outcome: Airflow and oxygen filtration components are clean, correctly installed, and serviceable.

7. Install the Annual PM Kit

Install annual PM kit P/N 1054378 / Order No. 453561512681.

Follow the current instructions packaged with the kit because kit contents may change.

Reassemble the ventilator before powered testing.

Expected outcome: Manufacturer-provided annual maintenance components are correctly installed.

8. Perform Electrical Safety Testing

Check protective-earth resistance at:

• Gas outlet port
• Proximal-pressure port
• Oxygen-fitting retention-plate screw

Manufacturer limit: Less than 0.2 Ω at each test point.

Verify forward and reverse leakage current:

• 100–120 VAC, 60 Hz: Less than 300 µA
• 220–240 VAC, 50 Hz: Less than 500 µA

Verify:

• Power-on self-test passes.
• Cooling fan operates correctly.

Do not substitute the general ≤ 0.5 Ω facility wording for this PM. The V60 service manual specifies the stricter less-than-0.2 Ω limit.

Expected outcome: Protective-earth resistance and forward and reverse leakage current meet the applicable manufacturer limits.

9. Perform High-Pressure Oxygen Leak Test

Connect the oxygen supply, shut-off valve, and pneumatic analyzer using the manufacturer test setup.

Verify oxygen inlet pressure is approximately 45–50 psig for the test, then run the Diagnostic-mode High Pressure Leak Test and follow the on-screen instructions.

Expected outcome: The high-pressure oxygen side of the gas-delivery subsystem passes the automated leak test.

10. Perform System Leak Test

Using the manufacturer-listed plugs, syringe, clamp, and test configuration:

• Seal the air inlet, gas outlet, and patient-pressure port.
• Connect the system-leak syringe to the internal exhalation port.
• Run the Diagnostic-mode System Leak Test.
• Follow the on-screen prompts.
• Remove all plugs and reinstall the inlet components after testing.

Expected outcome: The low-pressure gas-delivery subsystem and internal pneumatic connections pass the system-leak test.

11. Verify Controls

In normal ventilation mode, verify:

• AC icon
• Green On/Shutdown LED
• Touchscreen response across the display
• Navigation-ring rotation
• Navigation-ring Enter button
• Setting selection and acceptance
• Alarm-reset and alarm-silence controls
• Power-down control

Expected outcome: Every control responds consistently and correctly.

12. Verify Pressure Accuracy

Using the manufacturer pressure-test setup:

• Confirm displayed barometric pressure is within ±3.5% of the analyzer.
• Zero the analyzer and pressure transducers.
• Verify machine and proximal-pressure readings.

Manufacturer test points:

• 0 cmH₂O set pressure: Acceptable reading −1.00 to +1.00 cmH₂O
• 1 cmH₂O set pressure: Acceptable reading 0.50 to 1.50 cmH₂O
• 35 cmH₂O set pressure: Acceptable reading 31.5 to 38.5 cmH₂O
• 60 cmH₂O set pressure: Acceptable reading 54.0 to 66.0 cmH₂O

Apply the zero-offset calculations described in the service manual when evaluating machine and proximal-pressure readings.

Expected outcome: Both pressure channels pass all manufacturer-listed points.

13. Verify Air Delivery and Air-Flow Accuracy

Record barometric pressure and use the corresponding manufacturer compensation values.

The air-delivery portion is not performed below 600.1 mmHg. Document it as not applicable when below that pressure.

Verify air-flow accuracy:

• 10 SLPM set flow: Acceptable analyzer and displayed air flow 8.4–11.6 SLPM
• 120 SLPM set flow: Acceptable analyzer and displayed air flow 107.4–132.6 SLPM

After removing the internal-exhalation-port plug, flow must decrease by at least 8 SLPM and no more than 30 SLPM.

For the Certifier FA Plus setup, delivered-gas and ambient-air temperatures must be within 10°C of each other, and the manual specifies relative-humidity conditions for accurate measurement.

Expected outcome: Blower output and air-flow sensing pass the applicable altitude and environmental criteria.

14. Verify Oxygen-Flow Accuracy

Use medical-grade oxygen and configure the analyzer for oxygen at STP.

Verify:

• 10 SLPM set oxygen flow: Acceptable analyzer and displayed O₂ flow 8.4–11.6 SLPM
• 140 SLPM set oxygen flow: Acceptable analyzer and displayed O₂ flow 125.4–154.6 SLPM

The oxygen source must maintain at least 40 psig at 140 SLPM.

Expected outcome: Oxygen-flow sensor and oxygen-control valve pass both flow points.

15. Verify Oxygen-Mix Accuracy

First verify that setting oxygen above 21% without an oxygen source produces the Oxygen Not Available alarm.

Reconnect oxygen and calibrate the analyzer’s oxygen sensor.

Verify delivered oxygen:

• 21% set O₂: Acceptable measured O₂ 16–26%
• 30% set O₂: Acceptable measured O₂ 25–35%
• 60% set O₂: Acceptable measured O₂ 55–65%
• 100% set O₂: Acceptable measured O₂ 95–105%

Allow approximately one minute at each setting before recording the value.

Expected outcome: Oxygen alarms and delivered oxygen concentration meet manufacturer criteria.

16. Verify S/T Performance

Use the manufacturer patient-circuit, analyzer, and test-lung configuration.

Set the test lung to:

• Resistance: Rp20
• Compliance: 20

Verify cycling between IPAP and EPAP.

Manufacturer test points:

• IPAP 40 cmH₂O: Acceptable PIP measurement 36.4–43.6 cmH₂O
• EPAP 25 cmH₂O: Acceptable PEEP measurement 22–28 cmH₂O

Expected outcome: The ventilator cycles normally and delivered inspiratory and expiratory pressures pass.

17. Verify Alarm Outputs and Remote Alarm

Verify:

• Primary audible alarm
• Visual alarm indication
• Alarm LED
• Alarm reset
• Alarm silence
• Audible alarm remains detectable at loudness setting 1
• Alarm becomes progressively louder through setting 10
• Proximal-pressure-line disconnect alarm
• Automatic alarm silencing after reconnection
• Remote alarm normally open and normally closed contacts

Manufacturer remote-alarm contact criteria:

• No active high-priority alarm: TIP contact open circuit; RING contact 0–3 Ω
• Active high-priority alarm: TIP contact 0–3 Ω; RING contact open circuit

Expected outcome: Local audible and visual alarms and remote-alarm relay contacts operate correctly.

18. Verify Power-Fail Alarm

Test the power-fail alarm without the internal battery supplying the ventilator.

Disconnect AC power while the ventilator is operating and verify:

• Audible power-fail alarm activates.
• Alarm continues for at least two minutes.
• Holding the On/Shutdown button for approximately five seconds silences the alarm.

Reconnect the internal battery after the test when installed.

Expected outcome: The independent power-fail alarm remains active for the manufacturer-listed duration.

19. Test the Internal Battery

Perform this test only when an internal battery is installed. Fully charge the battery before testing.

Verify:

• Transition from AC to battery is uninterrupted.
• Initial diagnostic battery voltage is greater than 15.0 VDC.
• Operate for at least 20 minutes at 10 cmH₂O in Diagnostic mode.
• Battery voltage after 20 minutes remains greater than 14.0 VDC.
• Ventilator starts and operates from battery.
• “Running on Internal Battery” is displayed.
• Battery In Use icon is displayed.
• Battery Low alarm remains off.
• Transition back to AC is uninterrupted.
• AC icon appears.
• Battery-use icon clears.
• Battery Charging LED begins flashing within 30 seconds.

When the battery is not fully charged and the test cannot pass, the manual directs documenting the device as Limited use until the battery is charged and the test passes.

Expected outcome: Battery voltage, operation, power transfer, and charging indication meet all criteria.

20. Reset PM Information and Restore Configuration

After successful performance verification:

• Reset hours since last PM using the manufacturer service command.
• Capture required information before clearing the diagnostic log.
• Clear the Significant Event Log.
• Restore default ventilation and alarm settings.
• Verify and correct the date and time.
• Verify the internal exhalation-port orifice is not plugged.
• Recheck the proximal-pressure-line disconnect alarm in normal ventilation mode.
• Remove all test adapters, plugs, tools, and materials.
• Complete and apply PM and electrical-safety labels.
• Cover the labels with a chemical-resistant protective label when used by the facility.

Expected outcome: No test fixture remains installed, default settings are restored, and final alarm operation is confirmed.
