Manual Reference
Dräger Resuscitaire Instructions for Use, software 2.20, document MU26771, and current model-, module-, serial-, and region-specific Dräger technical documentation. The reviewed official IFU is a current Croatian-language edition; maintenance tables, numeric criteria, and service boundaries were cross-checked against Dräger’s official product and blender-maintenance publications. Current controlled documentation for the installed configuration governs.
Manufacturer Recommendation / AEM Status
- Inspection and safety checks: Every year by service personnel.
- Device service and maintenance: Every year by service personnel.
- Scale accuracy: At least annually when a scale is installed, and as needed when accuracy is questionable. Calibrate the standard scale as needed; OIML/NAWI scale work belongs to service personnel and applicable metrology requirements.
- Blender: Every two years when installed. The module must be returned to Dräger for calibration; Dräger’s PM bulletin states the blender must be calibrated or replaced every two years.
- Skin probes and probe covers: Replace between patients and weekly under the reviewed maintenance table.
- Suction bottle and filter: Replace between patients, when full, or as required for the fitted disposable/reusable system.
- Mattress, oxygen hose, and air hose: Replace as needed based on condition and the exact configuration.
Only facility-authorized service personnel may perform Resuscitaire preventive maintenance; specialized diagnostic, pneumatic, calibration, or internal work requires appropriately qualified personnel and current technical documentation. If the facility changes a manufacturer-listed interval or activity, manage the change through its approved AEM program, risk assessment, maintenance history, and applicable regulatory requirements.

Safety: Never perform maintenance with an infant on the warmer. Provide verified alternate warming and resuscitation equipment, clean and disinfect the unit, disconnect electrical and gas supplies, relieve residual pressure before service, and allow hot components to cool. Oxygen-rich systems present fire risk; keep oil, grease, ignition sources, and unapproved materials away.
Step-by-Step PM Procedure
1. Remove the Infant Warmer From Clinical Use
Action: Confirm no infant depends on the warmer or its resuscitation functions, provide alternate equipment, remove patient-use supplies, label the unit unavailable, and complete the current cleaning and disinfection procedure.
Expected outcome: The Resuscitaire is clean, cool, depressurized as required, and safe for maintenance.
2. Identify the Exact Configuration and Due Work
Action: Record asset tag, exact warmer and module model numbers, serial number, software, mains rating, operating location, service dates, and installed height, scale, gas, blender, cylinder, resuscitation, AutoBreath, suction, examination-light, shelf, and accessory options. Review complaints, repairs, drops, liquid entry, alarms, field actions, and prior results.
Expected outcome: The asset matches the CMMS record and the correct annual test path, two-year blender status, parts, service procedures, and optional tests are established.
3. Inspect Documentation, Labels, and Physical Condition
Action: Confirm the current IFU is available and labels are complete and legible. Inspect housings, fasteners, heater head and secondary reflector, controller, display, controls, power cord, plug, strain reliefs, grounding parts, connectors, cables, skin probes, mattress, bed, side/front/rear panels, X-ray tray, shelves, IV pole, mounts, and accessories. Check the reflector directly below the heater element for particles; follow Dräger service instructions if particles are present.
Expected outcome: The unit is complete, clean, unmodified, and free of cracks, contamination, loose parts, heat damage, damaged insulation, or unsafe heater debris.
4. Check Mobility, Height, Tilt, Barriers, and Heater Position
Action: Verify unlocked castors roll smoothly, locked castors hold, and directional locks work where fitted. Check height adjustment, Trendelenburg/reverse-Trendelenburg movement, bed attachment, panels and latches, X-ray tray, and accessory load security. Rotate the heater head 90° left and right where designed and return it to the operating position.
Expected outcome: The warmer is stable; brakes and steering work; all movements are smooth and controlled; panels remain secure; and the heater head and bed geometry are safe.
5. Run Startup Self-Test and Controls
Action: Reconnect approved power and start the unit. Verify diagnostic self-test, LED illumination except the power-fail indicator during the normal sequence, audible tones, the expected prewarm indication, display segments, controls, mode selection, key lock, and status indicators. Confirm no unresolved system fault is present.
Expected outcome: Startup completes normally, indications are clear, controls respond, and the warmer enters the expected ready/prewarm condition.
6. Verify Heater and Manual-Mode Operation
Action: With the bed empty and heater correctly aligned, verify heater-output bars increase and decrease with the manual heat control. Inspect for abnormal odor, arcing, noise, discoloration, intermittent output, or excessive heat outside the intended area. Test the examination light when installed.
Expected outcome: Heater indication and radiant output respond consistently, the examination light operates, and no unsafe condition appears.
7. Verify Skin-Probe Circuits and Baby-Temperature Mode
Action: Inspect and connect a verified skin probe or approved simulator. Confirm a plausible temperature display and appropriate control response. Under the controlled annual safety-check procedure, qualified personnel verify each applicable skin-probe channel reads 35.90 °C to 36.10 °C with the manufacturer-specified 4300 Ω test input; complete the documented A/D-converter and system-fail checks, including the specified 3655 Ω fault input where required.
Expected outcome: Both fitted probe channels measure correctly, baby-temperature control responds, and all diagnostic values meet the exact service-procedure limits.
8. Verify Temperature and System Alarms
Action: Verify audible and visual alarm paths, probe-disconnect response, loss of displayed baby temperature after probe removal, power-fail alarm, system-fail protection, overtemperature indication, and baby-temperature deviation alarm. Confirm the key lock prevents unauthorized mode/set-point changes. Test the manual-mode Check Patient alarm using the manufacturer procedure.
Expected outcome: Required alarms are audible and visible, identify the correct condition, and clear only after the fault is corrected. The reviewed annual criteria include baby-temperature alarm activation when measured temperature differs by more than 1.1 °C from set temperature and Check Patient activation every 10 minutes at 100% heater operation.
9. Verify APGAR Timer and Remaining User Functions
Action: Start and stop the timer and verify audible APGAR indications at 1, 5, and 10 minutes. Test remaining controls, displays, ports, and accessories applicable to the installed unit.
Expected outcome: Timer functions and every fitted user control operate consistently without an unresolved message or intermittent response.
10. Inspect Gas Supplies and Perform Leak Tests
Action: For gas-equipped units, inspect oxygen/air hoses, indexed connectors, regulators, gauges, cylinder restraints, dates, seals, piping, and relief components. Replace damaged hoses as needed. Using the exact controlled setup, test each high-pressure cylinder circuit and low-pressure pipeline circuit. The reviewed annual criteria permit less than 50 psi loss in 5 minutes from greater than 1200 psi for an isolated high-pressure cylinder circuit, and less than 10 psi loss in 5 minutes from 40 to 75 psi for an isolated low-pressure circuit.
Expected outcome: Supplies are correctly identified, secure, within range, and leak-free within the applicable manufacturer criterion. Any odor, audible leak, damaged connector, crossed gas, or failed decay test removes the unit from service.
11. Verify the Optional Blender
Action: Confirm the blender’s two-year calibration/replacement status. At annual inspection, use a calibrated oxygen analyzer and the approved gas setup to compare delivered oxygen concentration with multiple selected settings; verify the gas-supply imbalance alarm using the controlled procedure. Do not open or locally adjust the blender unless expressly authorized.
Expected outcome: Delivered oxygen is within ±4% O₂ of the selected setting under the reviewed annual criterion, the imbalance alarm occurs at the documented differential, and the module has been returned to Dräger for calibration or replaced at the two-year interval.
12. Verify Resuscitation Gas Flow, Pressure, and AutoBreath
Action: Identify the exact resuscitation module before testing. With calibrated analyzers and the approved fixture, test patient outlets, flow controls, airway-pressure gauge, adjustable pressure limit, relief functions, and patient circuit. When AutoBreath is installed, verify rate, I:E behavior, PEEP, and pressure response using its module-specific criteria. Do not substitute limits from another module or regional variant.
Expected outcome: Flow and airway pressure are stable and agree with the exact module settings and published tolerances. For applicable reviewed configurations, the airway-pressure gauge agrees with the external gauge within ±2 cmH₂O and AutoBreath delivers 36 to 44 breaths/min at a setting of 40 breaths/min under the specified 5 L/min test condition.
13. Verify Optional Suction
Action: Inspect the fitted bottle, lid, hydrophobic filter, tubing, gauge, control, and patient connection. Replace disposable components between patients, when full, or as needed. With the approved setup, verify adjustment, maximum blocked vacuum, open-flow indication, and zero indication when switched off.
Expected outcome: Suction is controllable and leak-free. The reviewed annual criteria require less than 30 mmHg indication at maximum with no blockage and no bottle connected, 140 to 160 mmHg with the bottle connected and proximal port blocked, and no pressure indication when suction is off.
14. Check the Optional Scale
Action: Confirm the scale is level, securely installed, undamaged, and configured for the correct local altitude/latitude where required. Check zero, tare, stability, units, and accuracy with calibrated weights at least annually. Calibrate the standard scale with the specified 5 kg weight when required; refer OIML/NAWI calibration and verification to qualified personnel under applicable metrology rules.
Expected outcome: The scale passes its annual accuracy check and its calibration or legal-verification status is current.
15. Perform Electrical Safety Testing
Action: Test the complete installed configuration according to the current Dräger procedure and the governing IEC 62353 or IEC/EN 60601-1/UL 60601-1 method. Include the warmer, scale power supply, powered height system, and electrical accessories as applicable. Record analyzer identification, method, equipment class, test points, limits, and results.
Expected outcome: Protective-earth and leakage measurements applicable to the exact configuration pass their documented limits.
16. Reassemble and Complete the Operational Checkout
Action: Remove test equipment, restore covers, tubing, bottles, filters, mattress, panels, accessories, and approved settings. After cleaning and reassembly, perform the complete Dräger operational-check procedure for the installed configuration. Repeat startup, heater, controls, barriers, alarms, gas, suction, resuscitation, scale, mobility, and safety checks as applicable. Document measurements, parts, calibration status, failures, corrective work, and disposition.
Expected outcome: No test setup remains; every installed function passes; records are traceable; and the warmer is either formally returned to service or clearly quarantined.
