Draeger Fabius Tiro M
Dräger · Model Fabius Tiro M
Easy to Use - The modular design allows all standard system components to be stored in a single container so that assembly and disassembly of the unit is easily accomplished Flexible Gas Source - As an alternative in areas where a central gas supply is not available, Fabius® Tiro M can also use a defined oxygen generator Electronic Ventilator - Electronically controlled, piston-driven ventilator uses no drive gas, decreasing fresh gas usage overall Field Deployable: Robust system can withstand transport and continue to provide high-level functionality in field operations Simple, modular design allows for full set-up within 15 minutes, without the use of tools Entire system packs and ships in one container, ensuring delivery of a complete anesthesia machine to the field Easy-to-use interface reduces time required for clinicians to become familiar with the system.
Key tips
- ·A failed daily leak test takes the machine out of service immediately - there is no acceptable workaround.
- ·Never run an agent-specific vaporizer with the wrong agent, even briefly, during testing.
- ·CO2-absorbent exhaustion mimics several unrelated fault symptoms - rule it out early.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Fails the pre-use leak / machine check
HighSymptoms: Low-pressure or circle-system leak test fails, machine not ready for use.
Root cause: Breathing-circuit / absorber leak, a worn APL valve or bag arm, a CO2-absorber canister seal, or a vaporiser back-bar leak.
Ventilator / bellows or piston fault
HighSymptoms: Set tidal volume not delivered, bellows will not fill or hangs up, piston fault, PEEP not held.
Root cause: Bellows leak, a drive-gas valve fault, a flow-sensor fault, or a piston-seal fault.
O2 flowmeter / hypoxic-guard fault
MediumSymptoms: O2 flow not matching the setting, flowmeter float sticking, hypoxic-guard / ratio fault, no O2 flush.
Root cause: Worn flowmeter (rotameter), a hypoxic-guard link fault, or a flush-valve fault.
Vaporiser fault
MediumSymptoms: Agent output does not match the dial, back-bar leak, dial stiff.
Root cause: Vaporiser seating / O-ring, or an internal vaporiser fault (calibrate at an authorised centre).
Gas-supply / pipeline / O2-failure alarm
MediumSymptoms: O2-failure whistle / alarm, anti-hypoxia device cuts N2O, pipeline-pressure fault.
Root cause: Loss of pipeline / cylinder pressure, or a pressure-sensor fault.
Scavenging (AGSS) fault
LowSymptoms: Waste-gas scavenging alarm or not evacuating, theatre pollution.
Root cause: Scavenging flow / connection or a receiver-valve fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily pre-anesthesia machine check: leak test, O2 sensor calibration, per facility protocol
- ·Scheduled vaporizer calibration and agent-specific service
- ·Absorber / CO2 canister replacement
- ·Breathing circuit and hose inspection
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Leak / machine check fails
- Run the check with the exact circuit and absorber.
- Reseat the CO2-absorber canister and check its seal; replace exhausted absorbent.
- Inspect the breathing-system gaskets, bag arm and APL valve.
- Check each vaporiser is seated with an intact O-ring.
- Re-run the check; escalate an internal leak that cannot be localised.
Symptom: Ventilator not delivering set volume
- Verify tidal volume with a calibrated gas-flow analyser.
- Inspect the bellows / piston and its seal for leaks.
- Calibrate the flow sensors.
- Check the drive-gas valve and circuit compliance compensation.
- Replace the bellows / flow sensors as isolated and re-verify.
