Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
ECG lead-off / artifact
MediumSymptoms: Flat or noisy ECG, frequent lead-off alarms.
Root cause: Worn electrodes, loose leads, or dry gel.
SpO2 probe / sensor failure
MediumSymptoms: No pleth, SpO2 drops to --- or false low.
Root cause: LED/photodiode aging or cable damage.
Internal battery depletion
HighSymptoms: Short backup time, battery alarm on transport.
Root cause: Aged backup battery.
Display / touch panel fault
LowSymptoms: Dim, flickering, or unresponsive screen.
Root cause: Backlight or digitizer failure.

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.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: ECG lead-off / artifact
- Confirm the presentation - typically flat or noisy ECG, frequent lead-off alarms - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: worn electrodes, loose leads, or dry gel.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the eCG patient cable & lead set per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: SpO2 probe / sensor failure
- Confirm the presentation - typically no pleth, SpO2 drops to --- or false low - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: lED/photodiode aging or cable damage.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the spO2 sensor (adult/ped/neo) per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

- RECALL
Unintended shut-down: The anesthesia machine may start shutting down without human intervention due to a faulty On/Standby Switch. Prior to shutdown, the system will issue an alarm and play a message that shutdown will occur in 8 seconds. The failure only affects the electrical portion of the switch. If the clinician does not intervene, the patient could experience hypoventilation leading to h

Issue 1 -Possible failure of CIC Pro audible alarms: Requests for telemetry defaults from Mobile Care Server could cause excessive CIC Pro memory consumption. This excessive memory consumption may lead to potential loss of audio at the CIC or a system reset or reboot. Issue 2 - Mobile Care software/Mobile Viewers don not recognize ApexPro FH Telemetry transmitter: Mobile Care server does not ac

There is a correction associated with Engstrom Carestation with an integrated Aerogen Professional Nebulizer System. There is an issue relating to the removal of the nebulizer cable from nebulizer connection port, which, when done while the nebulizer is active, may result in the discontinuance of mechanical ventilation. This issue affects all of the Engstrm Carestations shipped between 12/4/2006
- RECALL
Alarm sound-It is possible that the audible alarms from the speaker from the Datex-Ohmeda S/5 Anesthesia Delivery Unit (ADU) machine may dampen or disappear as a result of normal handling of the anesthesia machine. Visual alarms on the ADU are unaffected by this condition. The dampening or absence of audible alarms on the ADU may result in a delay in treatment.
