Class IIGMDN 10126
Baxter Sigma Spectrum Infusion Pump
Baxter International · Model Spectrum IQ / 35700 series
Large-volume infusion pump with master drug library (DERS), wireless connectivity, and peristaltic finger mechanism.
Intended use: Intermittent and continuous delivery of fluids, medications, blood products to pediatric and adult patients.
Key tips
- ·Free-flow protection must be verified on every PM - a failed anti-free-flow clamp is a direct overdose risk.
- ·Test occlusion alarms in both directions - failing to alarm when it should is more dangerous than a false alarm.
- ·Battery run-time complaints are the most common real-world nuisance call - a full charge/discharge cycle test catches most of them.
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.
Door latch mechanism wear
MediumSymptoms: 'DOOR OPEN' nuisance alarms, cassette misalignment
Root cause: Plastic latch fatigue from repeated loading cycles
Air-in-line ultrasonic sensor fouling
LowSymptoms: Persistent AIR alarm with clear line
Root cause: Dust/moisture in ultrasonic chamber
Battery cell failure
MediumSymptoms: Pump dies off AC immediately
Root cause: NiMH/Li pack end-of-life
Rotary encoder drift → rate inaccuracy
HighSymptoms: Delivered volume vs set volume mismatch beyond ±5%
Root cause: Encoder disk contamination

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.
- ·Occlusion pressure and flow-rate accuracy verification
- ·Battery conditioning cycle
- ·Door latch and air-in-line sensor inspection
- ·Post-drop functional check before return to service
- ·Annual PM per manufacturer schedule
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Pump repeatedly stops with 'flow error' mid-infusion
- Verify gravity bag height ≥ 60 cm above pump.
- Inspect segment of tubing inside channel for flattening, then rotate to fresh section.
- Confirm correct administration set brand is selected in setup.
- Run volume-delivered verification test with graduated cylinder (100 mL @ 100 mL/hr).
- If > ±5% deviation, calibrate or pull from service.
