Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Doppler probe / transducer wear
HighSymptoms: Weak, absent, or noisy Doppler signal.
Root cause: Probe crystal or cable wear.
Cuff / pneumatic system leak
MediumSymptoms: Inaccurate or failed pressure readings.
Root cause: Cracked cuff bladder or tubing/connector leak.
PVR waveform sensor drift
MediumSymptoms: Distorted or flat plethysmography waveform.
Root cause: Pneumatic transducer calibration drift.
Software / calculation fault
LowSymptoms: Incorrect ABI/TBI calculation, or frozen screen.
Root cause: Application software or workstation 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.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Doppler probe / transducer wear
- Confirm the presentation - typically weak, absent, or noisy Doppler signal.
- Check the most likely cause first: probe crystal or cable wear.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the doppler probe 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.
