Rejects all pulses ± 2.0 mV to ± 700 mV and duration 0.1 ms to 2 ms with 100 ms T.C. tail NIBP • Technique: oscillometric • Systolic range: adult/ped mode: 40-250 mmHg, neonate mode: 15-150 mmHg. • Diastolic range: adult/ped mode: 30-200 mmHg, neonate mode: 10-150 mmHg. • Systolic accuracy: mean error less than 7 mmHg, standard deviation less than 8 mmHg (adult/pediatric). Mean error less than 3 mmHg, standard deviation less than 13 mmHg (neonatal). • Diastolic accuracy: mean error less than 7 mmHg, standard deviation less than 8 mmHg (adult/pediatric). Mean error less than 4 mmHg, standard deviation less than 7 mmHg (neonatal). • Heart rate meter range: 30-250 bpm. • Heart rate meter accuracy: ±3 bpm or ±3%, whichever is greater. Pulse Oximetry • Accuracy (1standard deviation): 70-100%, ±2% 60-69%, ±4% 0-59%, unspecified. • Response time: 13 seconds to 95% of final step change % SpO2 value from 60-95% at 72 bpm
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.
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.
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.
