Baxter AP II
Baxter International · Model AP II
Lightweight, compact and battery-operated for portability A key is required to open the fluid bag cover and to enter or change a prescription preventing unauthorized access or changes to the medication or prescription. Infusion options offered by the APII are continuous infusion and/or Patient Controlled Analgesic (PCA) infusion. The Baxter APII PCA Pump performs extensive self-testing that will continuously monitor the operation of the pump. The rate range for this unit is 1-1000 mg/hr, volume 1-250 ml.
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Failure / error message
HighSymptoms: The pump alarms and displays an error message / code and stops delivery.
Root cause: A subsystem fault indexed in the service manual - motor / drive, a sensor, set-detection, or a board.
Occlusion alarm / pressure fault
MediumSymptoms: Repeated occlusion alarms, delivery stops, or an occlusion is missed.
Root cause: Kinked or clamped line, a closed roller clamp, a positional patient tube, a pressure-sensor drift, or an improperly loaded set.
Air-in-line alarm
MediumSymptoms: Frequent air-in-line alarms, delivery stops.
Root cause: Air in the set, an improperly loaded set, or an ultrasonic air-detector fault.
Flow-rate accuracy drift
MediumSymptoms: Delivered volume outside tolerance on the annual test, especially at low rates.
Root cause: Worn pumping mechanism / plunger drive.
Battery will not hold charge
MediumSymptoms: Short run time, low-battery early.
Root cause: Aged battery pack.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Error message / code
- Note the exact error message / code.
- Look it up in the pump's technical service manual troubleshooting section.
- Use the biomed diagnostics / utilities to test the affected subsystem.
- Follow the manual's parts-replacement procedure.
- Run the scheduled-maintenance test set (including flow accuracy) after any repair.
Symptom: Occlusion / delivery problem
- Check the line for kinks, clamps and a closed roller clamp; check the patient site.
- Reload the set correctly, clearing all air.
- Confirm an approved set for this pump.
- Run the pressure / air-detector (or rotor) test in diagnostics.
- Replace the set; refer the pump if a sensor / mechanism fault is indicated.
