Datex Ohmeda Ohmeda 7000
Datex Ohmeda · Model Ohmeda 7000
Calibrated electronic control allows for a more accurate ventilation delivery. Minute volume, I: E ratio and rate controls can adjust without affecting other setting Comprehensive alarms and safety features. Accommodates nearly any patient size.
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 self-test / circuit check
HighSymptoms: Self-test fault, circuit-leak or compliance-check failure, will not be released for use.
Root cause: Patient-circuit / expiratory-valve leak, a flow-sensor fault, an O2-cell fault, or an internal pneumatic fault.
Flow / volume delivery inaccurate
HighSymptoms: Delivered tidal volume or flow does not match the setting, or fails the annual verification.
Root cause: Flow-sensor drift / contamination, an inspiratory / expiratory valve fault, or a blender / proportioning-valve fault.
O2 / air supply or blender fault
MediumSymptoms: Low-supply alarm, FiO2 not matching the setting, O2-cell reads wrong.
Root cause: Wall / cylinder supply issue, an inlet filter / regulator fault, the blender, or an aged O2 cell.
PEEP not held / high circuit pressure
MediumSymptoms: PEEP drifts, auto-PEEP, high-pressure alarms, poor exhalation.
Root cause: Worn or wet expiratory valve / diaphragm, or a blocked exhalation path.
Battery / power fault
MediumSymptoms: Short internal-battery run time, will not charge, transfers to battery unexpectedly.
Root cause: Aged internal battery or a power-supply fault.
Turbine / compressor fault (turbine units)
MediumSymptoms: Noisy operation, cannot meet flow demand, turbine / compressor alarm.
Root cause: Worn turbine / compressor.

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: Fails the pre-use self-test
- Run the self-test with the exact circuit and humidifier that will be used.
- Leak-test the circuit and the expiratory valve; fit fresh flow sensors and an O2 cell if due.
- Repeat the self-test.
- Calibrate the O2 cell and flow sensors per the manual.
- Remove from service and refer an internal pneumatic fault to the OEM / biomed.
Symptom: Delivered volume or FiO2 wrong
- Verify tidal volume / flow with a calibrated gas-flow analyser and FiO2 with an analyser at the wye.
- Calibrate the flow sensors and O2 cell.
- Inspect the inspiratory / expiratory valves.
- Check the air / O2 supply pressures and inlet filters.
- Refer the blender / proportioning valve for service if the mix is still wrong.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
The electronic vaporization system in the GE Aisys Anesthesia machine contains the following components: Backpressure Valve, Inflow Check Valve and Cassette Interface Board, that can contribute to independent failures.
- RECALL
Neonatal Flow Sensors supplied for use with the Neonatal Enhancement for the Engstrm Carestation may result in the sensors providing invalid values and alarm messages when exposed to high flow rates.
- RECALL
Certain Compact Absorbers may have an increased resistance to gas flow due to an improperly manufactured foam filter. The increased resistance can cause an elevated pressure at the ventilator end of the inspiratory circuit, but the pressure at the patient may be reduced. This could result in patient hypoventilation and hypoxia.
- RECALL
Vaporizer shutdown with alarm-An intermittent leak in the Aladin 2 cassette/Aisys pneumatic interface (valves) may occur that will invoke an alarm state. When this occurs 'Vaporizer Failure' will appear on the Aisys main display, with an accompanying audible alrm. Delivery of anesthetic Agent is halted; gas flow and ventilation are not affected.
- RECALL
Two conditions may occur with the S/5 Aespire Anesthesia System. The internal auxiliary flowmeter tubing may become disconnected if the auxiliary oxygen supply tubing is occluded and the patient may not receive desired supplemental oxygen which could lead to serious injury if undetected. Also the O2 switch may leak or fail.
- RECALL
Phototherapy medical device may lose its position and can cause a safety hazard to the patient.
- RECALL
Anesthetic agents could be delivered at concentrations above the concentration set on the S/5 and AS/3 Anesthesia Delivery Units (ADU) having serial numbers within a specified range.
- RECALL
Datex-Ohmeda Cardiocap/5 Patient Monitors have bracket pins which do not adequately secure them to their optional mounting stand so the monitors may fall.
- RECALL
Possible disruption of mechanical ventilation or disruption of anesthetic agent delivery.
