Legacy-product notice: Medtronic lists the PB560 and associated service material among legacy ventilator products affected by obsolescence. Verify current support, approved-part availability, recalls, field actions, and the exact serial-number status before beginning scheduled work.
Manufacturer Recommendation / AEM Status
- Before use, after service, and as clinically required: Complete the applicable operational checks, verify alarms and power sources, and inspect the patient circuit and accessories.
- Monthly or sooner if soiled: Replace the foam and fine-particle air-inlet filter. Check it more often in dusty environments or when the ventilator is wheelchair-mounted.
- Each new patient / condition based: Use a single-patient circuit as labeled, replace the single-patient exhalation block for each new patient, and follow the bacteria-filter manufacturer's interval.
- Exhalation block: Replace every four months during normal use. The clinician manual notes three months for tracheostomy patients ventilated more than 12 hours per day and permits extension to six months for patients ventilated less than 12 hours per day depending on technician-visit frequency.
- FiO2 sensor: Replace after 14–18 months or sooner for persistent calibration failure.
- Annually: Perform the service-manual checkout: POST, visual inspection, electrical safety, full performance verification and sensor calibrations; clean and dry the inspiratory block and recalibrate the inspiratory-flow sensor; verify computed battery capacity is greater than 3,840 mAh.
- Every 15,000 operating hours: Replace the oxygen solenoid valve, turbine, exhalation solenoid valve, and cooling fan, followed by required calibration and performance verification.
The service manual is written for biomedical technicians or equivalent personnel who completed Covidien product training. Internal repair, maintenance-mode calibration, 15,000-hour parts replacement, and testing with exposed energized electronics must stay within the technician's training and the controlled service procedure. Any altered activity or interval belongs under the facility's approved AEM program and documented risk assessment.

Procedures involving an open energized unit require the controlled service manual, ESD controls, suitable training, and extreme caution.
Step-by-Step PM Procedure
1. Remove the Ventilator From Clinical Use
Action: Confirm that no patient is connected, provide alternate ventilation, stop ventilation through the normal control, switch the unit off, label it unavailable, and clean or disinfect external surfaces and reusable accessories according to the manual and facility policy.
Expected outcome: Maintenance can proceed without interrupting therapy or exposing personnel to contamination.
2. Verify Identity, Configuration, and Service Status
Action: Record the asset tag, serial number, software versions, machine hours, patient hours, language and date/time settings, circuit type, exhalation block, FiO2 kit and sensor, oxygen connection, internal and external batteries, power supplies, remote alarm, mount, carrying bag, humidifier, and other accessories. Review prior repairs, faults, calibration results, battery capacity, replacement dates, recalls, field actions, and current manufacturer support.
Expected outcome: The tested configuration matches the CMMS record and all due, overdue, or unsupported work is identified.
3. Perform the Visual and Mechanical Inspection
Action: Inspect the housing, carrying handle, feet, labels, display, keys, alarm indicators, buzzer openings, power switch, ventilation outlet, proximal-pressure port and tubing, exhalation-valve port, FiO2 connection, oxygen inlet, air inlet and filter cover, cooling openings, USB and remote-alarm connections, AC/DC connectors, cords, strain reliefs, battery interfaces, circuit, exhalation block, accessories, mounting hardware, and carrying equipment. Check for cracks, impact, contamination, corrosion, liquid entry, loose parts, damaged pins, exposed conductors, blocked airflow, or insecure mounting.
Expected outcome: The complete system is clean, legible, secure, and free of visible electrical, pneumatic, or mechanical hazards.
4. Replace the Monthly Air-Inlet Filter
Action: Inspect the rear air-inlet filter and replace the foam/fine-particle element at least monthly or sooner when dirty. Increase inspection frequency for dusty locations or wheelchair use. Install the correct element in the specified orientation and keep the intake unobstructed.
Expected outcome: A clean, dry, correctly installed inlet filter permits unrestricted cooling and turbine airflow.
5. Inspect the Circuit, Filters, and Exhalation Block
Action: Verify that the circuit and inspiratory bacteria filter are appropriate, intact, dry, and within the component manufacturer's interval. Confirm the exhalation block is assigned to one patient, within its applicable three-, four-, or six-month interval, clean under the permitted instructions, and replaced for every new patient. Do not disinfect, sterilize, or transfer the single-patient exhalation block to another patient.
Expected outcome: The complete breathing system is correctly assembled, uncontaminated, unobstructed, and current for the patient and usage pattern.
6. Check the FiO2 System When Installed
Action: Inspect the FiO2 sensor, cable, fittings, oxygen source, regulator, tubing, and leak-free connection. Review sensor age and calibration history; replace the sensor at 14–18 months or for persistent calibration failure. Perform FiO2 calibration using the current manual, approved oxygen source, and certified oxygen reference.
Expected outcome: The oxygen system is secure and leak free, calibration completes without an alarm, and displayed oxygen concentration meets the controlled service-manual criteria.
7. Check Power Sources and Battery Condition
Action: Inspect and connect the approved AC supply, then verify the AC indicator and charging status. Verify approved external DC operation and any external battery or Power Pack included with the asset. Remove each external source in the prescribed sequence and confirm continued internal-battery ventilation, correct indicators, and expected alarms. Recharge fully after testing.
Expected outcome: Power transitions occur without shutdown; all sources, indicators, alarms, connectors, and charging functions operate correctly.
8. Complete POST and Review the Technical Fault Log
Action: Start the PB560 using the service-manual procedure, confirm the display, indicators, and audible alarm initialize, and verify POST passes. Through authorized maintenance access, record machine hours, software versions, serial number, and stored technical faults. Resolve active or clinically significant faults before continuing.
Expected outcome: POST passes, the audible and visual annunciators function, and no unresolved fault can affect safe operation.
9. Perform the Annual Measurement Check and Calibrations
Action: Using the controlled service manual and calibrated test equipment, perform the complete measurement check and all applicable patient-pressure, internal-valve-pressure, inspiratory-flow, expiratory-flow, and FiO2 calibrations. Clean and dry the inspiratory block as specified and recalibrate the inspiratory-flow sensor. Record every measured value and criterion.
Expected outcome: Every required measurement and sensor calibration completes successfully within the service-manual limit.
10. Verify Battery Capacity
Action: Use the annual service procedure to obtain the ventilator's computed internal-battery capacity. The service schedule requires capacity greater than 3,840 mAh. If the value is below 3,840 mAh, fully recharge and repeat the authorized evaluation; replace the battery if it cannot be restored above the criterion. Record capacity, charge state, age, cycle information when available, and replacement details.
Expected outcome: Computed battery capacity is greater than 3,840 mAh and the ventilator completes the prescribed battery and power-loss checks.
11. Verify Ventilation, Monitoring, and Alarms
Action: Connect the specified circuit and test lung and perform the complete annual performance-verification sequence. Check delivered pressure, PEEP, flow, volume, respiratory rate, inspiratory time, triggering, monitored values, leakage compensation, and applicable exhaled-volume measurement. Test high and low pressure, disconnection, occlusion, power, battery, FiO2, circuit/exhalation-valve, and other service-manual alarms, including silence/reset and recovery.
Expected outcome: All ventilation, monitoring, alarm, annunciation, silence/reset, and recovery results meet the exact service-manual criteria.
12. Complete 15,000-Hour Maintenance When Due
Action: At 15,000 machine hours, trained service personnel replace the oxygen solenoid valve, turbine, exhalation solenoid valve, and cooling fan with approved parts using the controlled instructions. Record part numbers, lots or serials, machine hours, and disposal. Complete all post-repair calibration and performance verification.
Expected outcome: Every due 15,000-hour component is replaced and the fully reassembled ventilator passes the required post-service testing.
13. Perform Electrical Safety Testing
Action: Run the PB560 service-manual electrical-safety sequence on the exact ventilator, AC supply, cord, and applied-part configuration. Record the analyzer, standard or method, line conditions, limits, and all applicable enclosure and patient leakage measurements. Perform the required safety test after installation, annual checkout, software service, preventive maintenance, or repair as directed by the manual.
Expected outcome: Every required measurement passes the limit specified by the controlled PB560 service procedure.
14. Restore the Configured System and Make the Service Decision
Action: Reinstall all covers, filters, batteries, circuit parts, and approved accessories. Clean the unit, confirm settings were not unintentionally changed, repeat POST and all testing required after the work performed, verify full charge and absence of alarms, and document parts, measurements, calibration reports, software, fault-log findings, support status, and final disposition.
Expected outcome: The PB560 is complete, correctly configured, fully verified, and formally returned to service—or clearly quarantined when any requirement remains unresolved.
