Philips Respironics Trilogy 100, 200, O2, and 202 only when the exact model-specific manual and service procedure support the activity. This page does not cover Trilogy Evo or Trilogy EV300. Confirm the model, REF, serial number, software, circuit type, options, PM label, and current field-action status before service.
Manual Reference
Philips Respironics Trilogy100 Clinical Manual, REF 1066819 / 1072847 R01; Philips Trilogy Workshop booklet 1061109; and the current model-, serial-, and software-specific Philips service documentation. Because reviewed Philips publications list different service intervals, the exact device PM label and current applicable documentation control.
Manufacturer Recommendation / AEM Status
- Exact interval check: The reviewed Trilogy100 clinical manual lists performance verification every 10,000 blower hours or two years, whichever comes first. A separate Philips Trilogy workshop booklet lists authorized maintenance every 12 months or 8,760 blower hours, whichever is sooner. Follow the exact device PM label and current applicable Philips documentation; do not average or interchange the schedules.
- Every two weeks while in use: Inspect and clean the gray air-inlet foam filter.
- Every six months while in use: Replace the air-inlet filter, inspect the enclosure and external connections, and inspect the power cord.
- Stored devices: Charge internal and detachable batteries fully before long-term storage and recharge them every three months while stored. The reviewed manual states that recharge should complete in eight hours or less.
- Every 17,500 blower hours, where the reviewed Trilogy100 schedule applies: Philips-trained service personnel replace the motor/blower assembly and perform full calibration and verification.
- Before initial patient use: Charge batteries fully and perform the applicable system checkout with the intended circuit configuration.
- Recall and correction status: Trilogy 100 and 200 devices have been subject to serial-specific Philips/FDA actions involving sound-abatement foam and certain reworked units. Verify the exact serial number and current disposition. Routine PM is not a substitute for required recall quarantine, correction, or replacement.
Performance verification, internal service, blower replacement, and calibration belong to Philips-trained or otherwise qualified personnel using controlled service information. If a facility changes a manufacturer-listed interval or activity, that change should be managed under its approved AEM program, risk assessment, maintenance history, and applicable regulatory requirements.

Safety: Never perform PM with a patient connected. Provide verified alternative ventilation before removing a device from clinical use. Only trained personnel may change test settings or perform service-level work, and every prescription and alarm setting must be restored and independently verified before release.
Step-by-Step PM Procedure
1. Remove the Ventilator From Patient Use
Action: Confirm that no patient depends on the unit, provide verified alternative ventilation, disconnect the patient circuit, label the ventilator unavailable, and follow infection-control precautions.
Expected outcome: Maintenance can proceed without interrupting therapy or exposing personnel to a contaminated circuit.
2. Verify Model, Configuration, and Applicable Documentation
Action: Record asset tag, exact Trilogy variant, REF, serial number, software, blower hours, PM-label date/hours, circuit type, batteries, power sources, oxygen configuration, remote alarm/nurse call, accessories, and current manual/service-document revisions. Confirm that the unit is not Trilogy Evo or EV300.
Expected outcome: The device and the correct maintenance schedule, test method, parts, and service boundaries are positively identified. Stop if the applicable configuration cannot be established.
3. Resolve Recall and Field-Action Status Before Routine PM
Action: Check the serial number against current Philips and FDA recall/correction information and the facility's field-action records. Document whether the device is unaffected, corrected, replaced, approved for continued use under current instructions, or subject to quarantine. Do not open the air path or treat routine filter work as foam remediation.
Expected outcome: The serial-level disposition is documented. Any unit requiring quarantine, return, correction, or replacement remains out of service regardless of routine PM results.
4. Review History and Due Maintenance
Action: Review alarms, unexpected shutdowns, pressure/volume complaints, unusual sound, overheating, drops, liquid entry, damaged enclosure, battery runtime, charging, circuit, recall, repair, and prior PM records. Compare the current blower hours and date with the PM label and exact applicable schedule.
Expected outcome: All complaints and due two-week, six-month, stored-battery, performance-verification, and blower/calibration activities are identified.
5. Clean and Inspect the Exterior
Action: Disconnect external power and remove the detachable battery as directed. Clean the ventilator exterior and battery exterior using the current manual and approved agents. Do not immerse the device or allow liquid into openings. Inspect the enclosure, handle, screws, rubber feet, SD-card door, labels, display, buttons, alarm indicator, speaker, cooling openings, circuit connections, exhalation porting block, oxygen connection, communication ports, and accessories.
Expected outcome: The unit is clean, dry, complete, secure, legible, and free of cracks, liquid entry, contamination, loose parts, or physical damage.
6. Inspect Power Equipment and External Connections
Action: Inspect the AC inlet, cord, plug, strain reliefs, detachable battery contacts and latch, external DC cable/source, remote alarm cable, nurse-call cable, oxygen fittings, and all external connections. Look for cuts, heat, corrosion, bent pins, looseness, exposed conductors, or unauthorized accessories.
Expected outcome: All connections and power components are correct, secure, and undamaged. Damaged cords or connections are replaced or referred for service before testing.
7. Complete Air-Inlet Filter Maintenance
Action: Remove the gray foam air-inlet filter. At the two-week interval, inspect and clean it exactly as directed, allow it to dry completely, and replace it if torn or damaged. At the six-month interval, install a new Philips-supplied filter. Inspect the filter area for abnormal debris without opening or altering the internal air path.
Expected outcome: A clean, dry, undamaged, correctly seated filter is installed and the applicable interval is documented. Unexpected debris or a contaminated air path requires evaluation under current Philips field-action guidance.
8. Evaluate Batteries and Charging
Action: Inspect the internal-battery status and detachable battery for damage, swelling, contamination, retention, age, and service history. Connect AC power and verify recognition and charging. For stored units, confirm full charging before storage and every three months; investigate any battery that does not fully recharge within the applicable manual's stated time. Review battery-cycle information during service-level PM when the controlled procedure requires it.
Expected outcome: Batteries are intact, recognized, charging, retained securely, and within their approved service status. No battery fault or unacceptable runtime history remains.
9. Complete Due Authorized Performance Verification
Action: Using the exact current service procedure, have Philips-trained or otherwise qualified personnel perform the required performance-verification test at the device's controlling interval. Record the PM label, blower hours, tools/software, measured results, calibration, parts, and new due date/hours. If the exact applicable schedule requires 17,500-hour motor/blower replacement and full calibration, complete that work before further testing.
Expected outcome: All controlled performance and calibration checks pass, restricted maintenance is complete, and the PM label and service record agree.
10. Run Startup and Basic Functional Checks
Action: Install verified batteries and accessories, connect AC power, and start the ventilator. Confirm the display, controls, audible alarm, alarm light, status indicators, date/time, power-source indication, and information menu operate normally. Confirm no service-required or unresolved technical alarm is present.
Expected outcome: The ventilator completes startup and reaches the correct ready/standby condition without an unresolved fault.
11. Perform the Model-Specific System Checkout
Action: Use the current model-specific checkout procedure, the intended active and/or passive circuit configuration, correct porting block/exhalation device, and test lung. Perform the complete sequence in the stated order. Use only the documented temporary test settings and acceptance criteria; do not invent or reuse settings from a different Trilogy variant.
Expected outcome: Visual inspection, circuit setup, ventilation response, and every required checkout step pass with the actual intended circuit type.
12. Verify Alarm Detection, Indication, and Reset
Action: Complete all alarms included in the applicable checkout, including representative high/low volume or pressure and circuit-disconnect tests as supported. Verify audible priority, alarm light, displayed message, response time, silence behavior, and automatic/manual reset. Test the remote alarm and nurse-call interface when installed using their current instructions.
Expected outcome: Each required alarm is correctly detected, announced, displayed, transmitted when applicable, and cleared. A failed or intermittent alarm is a remove-from-service condition.
13. Verify AC, DC, and Battery Power Transfer
Action: With the ventilator operating on the test lung, verify AC operation and charging. Remove AC power and confirm uninterrupted internal-battery operation and the correct alarm/indication. Test detachable-battery and approved external-DC operation where configured, then restore AC and confirm normal transfer and charging.
Expected outcome: Ventilation continues through each supported power transition, sources are identified correctly, expected alarms occur, and charging resumes without a shutdown or fault.
14. Verify Installed Options and Accessories
Action: Inspect and functionally verify the approved humidifier interface, oxygen connection, SD card, stand, in-use bag, oximetry, external battery, remote alarm, nurse call, and other installed accessories using their own instructions. Confirm accessories do not block cooling or interfere with circuit security.
Expected outcome: Every installed option is compatible, secure, functional, and documented or clearly marked not applicable.
15. Perform Configuration-Specific Electrical Safety
Action: Use the controlled Philips service procedure and facility policy for the exact ventilator, power cord, equipment class, and connected accessories. Record analyzer identification, test standard/method, governing limits, chassis/touch leakage, and any other required measurements. Do not assume protective-earth resistance applies to a configuration without a protective-earth conductor.
Expected outcome: All applicable electrical-safety measurements pass the documented criteria for the exact configuration.
16. Restore Settings and Complete Final Verification
Action: Remove all temporary test settings and restore the prescribed clinical configuration and alarm settings from the authorized record. Independently compare every setting, circuit type, porting block, accessory, and alarm limit. Repeat the required final checkout, clear test logs only when authorized, clean the unit, and document parts, measurements, field-action status, failures, corrective work, and disposition.
Expected outcome: No test setting remains, the configured system passes final verification, documentation is complete, and the unit is either formally returned to service or clearly quarantined.
Electrical Safety Testing
The reviewed public clinical material does not provide one universal leakage-current limit for every Trilogy variant, equipment class, power source, and accessory combination. Use the current controlled Philips service procedure, facility policy, and the exact configuration. Record N/A - no protective-earth conductor for ground resistance only when confirmed by inspection and documentation; do not create a ground path or report a fabricated value.
