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.
NIBP measurement error
MediumSymptoms: Cuff fails to inflate, erroneous BP, long cycle.
Root cause: Pump/valve wear or cuff leak.
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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Beckman Coulter identified that LDL Cholesterol OSR6x96 is not meeting the performance claim listed in the Instructions for Use (IFU). LDL Cholesterol reagent showed clinically significant interference due to triglyceride concentration up to 1500 mg/dL may cause a maximum positive bias of up to 28.8% in low LDL Cholesterol samples (concentration 80 mg/dL) and up to 11.02% in high LDL Cholesterol samples (concentration 160mg/dL).
- RECALL
Access Thyroglobulin reagent lot 439163 may generate erroneously high patient results. Falsely increased Access Thyroglobulin results may lead a physician to pursue unnecessary diagnostic imaging studies and/or inappropriate therapy adjustments in patients being monitored for residual or recurrent thyroid cancer.
- RECALL
Software error: This field action was initiated after Beckman Coulter determined that the CXP software does not refresh the dataset automatically under certain circumstances. The User documentation does not clearly state that the user should refresh the dataset after changes are made.
