Manual Reference
Dräger Atlan A300 family Instructions for Use applicable to the installed software (current family edition includes SW 2.1n, document 9511481), applicable regional supplements, reprocessing instructions, and controlled technical service documentation. Verify A300/A300 XL configuration, software, gas mixer, integrated gas measurement, mounting type, options, and local revision before service.
Manufacturer Recommendation / AEM Status
Dräger requires an inspection and safety check every 12 months by service personnel. The current supplement also assigns a battery test every 3 months to the clinical user unless the powered-on device remains connected to mains without interruption. The complete system test is performed daily and after relevant service; it checks device functions, performs the leakage test, and calibrates valves and sensors.
Scheduled maintenance includes annual piston-diaphragm replacement; two-year inspiratory O₂ sensor, water-trap-holder O-ring, filter-cloth, and lead-battery replacement; four-year CLIC adapter replacement; and six-year pressure-reducer replacement when applicable. Condition- and Infinity ID-based consumables remain due sooner when indicated. Do not extend these intervals through an AEM program without the facility's documented risk assessment and approval.

Step-by-Step PM Procedure
1. Remove From Patient Use and Isolate Supplies
Action: Confirm no patient or procedure depends on the workstation. Provide a suitable backup anesthesia workstation, remove vaporizers/cylinders as required for safe handling, reprocess the device, and disconnect electrical and gas supplies before service access.
Expected outcome: The Atlan is unavailable for clinical use, decontaminated, and safely isolated.
2. Verify Identity, Software, and Configuration
Action: Record asset tag, serial number, A300 configuration, software version, trolley/ceiling/wall mounting, electronic or mechanical gas mixer, patient-gas measurement module, gases, vaporizers, oxygen sensor, battery, AGS, support arms, power outlets, and Infinity ID options.
Expected outcome: The system matches the CMMS record and the correct manual, supplements, parts, and test path are identified.
3. Review History and Scheduled Maintenance
Action: Review prior PM, system-test history, leak values, repairs, ventilation/gas/agent complaints, power failures, recalls/field actions, software updates, battery tests, and annual/multi-year component dates. Resolve open corrective work before release.
Expected outcome: All relevant history, service actions, and due intervals are known and documented.
4. Inspect Documentation, Labels, and Gas Identification
Action: Confirm the correct IFU is available. Inspect serial/rating/warning labels and accessible fuse ratings. Verify country-specific gas labels, connector indexing, cylinder/pipeline identification, and screen gas-type display agree exactly.
Expected outcome: Documentation and labels are present and the displayed/configured gases match the physical connections.
5. Inspect the Workstation and Mounting System
Action: Inspect trolley, casters, brakes, housing, drawers, work surface, screen, controls, status display, handles, rails, support arms/end stops, cable management, hoses, strain reliefs, connectors, power outlets, and ceiling/wall interface when applicable. Look for impact, looseness, corrosion, cracks, fluid entry, or blocked ventilation.
Expected outcome: The workstation is stable, complete, mobile/secure as configured, and free of visible mechanical or electrical damage.
6. Inspect Gas Supplies, Vaporizers, and Emergency Oxygen
Action: Inspect pipeline hoses/inlets, cylinder yokes/regulators/sensors, pressure reducers, gauges, check valves, O-rings, vaporizer mounts/interlocks, and vaporizers. Verify secure mounting and correct agent identification. Functionally test emergency O₂ delivery according to the IFU.
Expected outcome: Gas sources and vaporizers are correctly identified and secure, and emergency oxygen delivery functions as specified.
7. Inspect the Breathing System and Piston Drive
Action: Disassemble/reprocess as required and inspect the breathing-system housing, inspiratory/expiratory valves, APL valve, piston drive, piston diaphragm, absorber/CLIC adapter, bag arm, breathing bag, hoses, connectors, flow sensors, and seals. Replace the piston diaphragm annually and reassemble exactly as instructed.
Expected outcome: The breathing system is clean, dry, intact, correctly assembled, and fitted with a current diaphragm.
8. Inspect Sampling, Monitoring, and Scavenging
Action: Inspect water trap and holder, holder O-rings, sample line, patient-gas module, inspiratory O₂ sensor when fitted, AGS, AGS valves, transfer hose, receiving system, and particle filter. Replace soiled/expired components and verify unobstructed scavenging flow under the controlled procedure.
Expected outcome: Sampling and scavenging pathways are intact, leak-free, unobstructed, and current on maintenance.
9. Complete the Quarterly Battery Test
Action: Fully charge the batteries. Disconnect mains and confirm the Power failure alarm. Operate for 30 minutes in volume-controlled ventilation with VT 500 mL, RR 10/min, I:E 1:1.5, PEEP 5, and fresh-gas flow 10 L/min. Restore mains afterward.
Expected outcome: No Battery failure, Battery charge low, or Battery charge very low alarm occurs during the 30-minute test, and mains restoration/charging is normal.
10. Prepare for the Automated System Test
Action: Connect the required oxygen/air supplies, AGS, breathing circuit, test lung, bag, absorber, water trap/sample line, flow sensors, and vaporizers. Complete the on-screen checklist/walk-through and correct every preparation item before starting the automatic portion.
Expected outcome: The system is fully assembled in its intended test configuration and all checklist items pass.
11. Perform the System Test
Action: Run the complete automated system test. Remain at the workstation during initialization and respond to prompts. Confirm calibration of valves and sensors, component/function checks, gas identification where supported, and completion of the automatic leakage test. Record the overall result and test history.
Expected outcome: The system test finishes successfully with no unresolved limitation, failed component, or restricted operational status.
12. Perform the Leakage Test After Service
Action: Run the leakage test after filling/replacing the absorber, changing hose configuration, replacing/reinstalling the breathing system or piston diaphragm, replacing flow sensors, working on the vaporizer interface, or whenever leakage is suspected. Record leakage, system compliance, and resistance; use the leakage assistant to localize an abnormal result.
Expected outcome: Leakage, compliance, resistance, and any required valve/flow-sensor calibration meet the current controlled acceptance criteria.
13. Verify Ventilation and Fresh-Gas Performance
Action: Using the calibrated analyzer and controlled service procedure, verify representative volume- and pressure-controlled ventilation, tidal volume, respiratory rate/timing, airway pressure, PEEP, fresh-gas flow and composition, oxygen concentration, manual/spontaneous ventilation, APL function, and monitoring accuracy.
Expected outcome: Delivered and measured ventilation and fresh-gas values meet every applicable Dräger tolerance.
14. Verify Vaporizers, Agent Monitoring, and O₂ Safety
Action: Check each compatible vaporizer for mounting, interlock, agent identification/recognition, fill/drain condition, leaks, and output using its separate controlled procedure. Verify oxygen monitoring/calibration, oxygen-ratio/hypoxic-mixture protection as configured, O₂ flush, and patient-gas O₂/CO₂/agent measurement.
Expected outcome: Anesthetic-agent delivery and monitoring are accurate and stable, and all oxygen safety functions pass.
15. Verify Alarms and Failure Responses
Action: Test required airway-pressure, volume, apnea, oxygen, agent, gas-supply, circuit/leak, scavenging, sensor, power, battery, and system alarms using controlled non-patient conditions. Verify audible/visual indications, alarm light, speaker, priority, silence, reset, and safe fallback behavior.
Expected outcome: Every required alarm and failure response is detected, indicated, sounded, and cleared as specified.
16. Verify Scheduled Replacement Components
Action: Confirm annual piston diaphragm; two-year inspiratory O₂ sensor, water-trap-holder O-rings, filter cloths above the gas mixer/power supply, and two lead batteries; four-year CLIC adapter; and six-year pressure reducer when fitted. Replace flow sensors, absorber, water trap, AGS/particle filter, and other condition/Infinity ID items when indicated.
Expected outcome: Every applicable time-, condition-, and usage-based component is current and traceable.
17. Perform Electrical Safety Testing
Action: Test the complete workstation and electrically connected accessories according to the IEC 62353 procedure below. Include installed power outlets, support equipment, gas-monitoring components, and ceiling/wall interfaces as applicable. Record actual readings and limits.
Expected outcome: All required electrical-safety measurements meet current Dräger and adopted-standard criteria.
18. Restore, Retest, and Document
Action: Reprocess and reassemble the workstation, reinstall approved vaporizers/accessories, restore facility settings, reconnect gases/mains, and run a final successful system test after service. Document tests, leakage/compliance/resistance, analyzer readings, parts, battery result, corrective work, and disposition.
Expected outcome: The Atlan is clean, fully assembled, current on maintenance, and either returned to service with a successful final system test or clearly removed from service.
Electrical Safety Testing
The annual Atlan safety check requires electrical safety verification according to IEC 62353. Begin with inspection of mains cords/plugs, inlets, accessible fuses, strain reliefs, equipotential/protective-earth connections, outlets, enclosure, display, gas-monitoring modules, cables, power supplies, and accessible conductive parts. Include the exact trolley, ceiling, or wall configuration and connected accessories covered by the controlled procedure.
Use the limits specified by the current Dräger technical documentation and the facility's adopted IEC 62353 method; do not substitute generic numeric limits from another anesthesia platform. Record the test method, configuration, limits, and actual readings. Remove the workstation from service for damaged insulation, unreliable protective earth, excessive leakage/touch current, an unsafe outlet, or any incomplete required test.
