CareFusion Alaris Medley
CareFusion · Model Alaris Medley
The Medley System is intended for use in hospitals and healthcare facilities on adult, pediatric and neonatal patients. The Alaris PC Point-of-Care Unit is the core of the Alaris System, which provides a common user interface for programming the infusion and monitoring modules, helping to reduce complexity at the point of care.
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.
Error message / error code on the PC Unit or module
HighSymptoms: The system alarms and displays an error message / code, therapy inhibited.
Root cause: A specific fault indexed in the Technical Service Manual troubleshooting chapter - a module, cable, connector, or board fault; use the maintenance software to diagnose.
Pump module: occlusion / air-in-line alarm
MediumSymptoms: Repeated occlusion or air-in-line alarms on a Pump module, delivery stops.
Root cause: Kinked or clamped line, an improperly loaded set, or a pressure / air-detector sensor fault.
Module will not latch / not recognised by the PC Unit
MediumSymptoms: A module (Pump, Syringe, SpO2, EtCO2) will not attach or the PC Unit does not see it.
Root cause: Worn IUI connector on the module or PC Unit, or a module fault.
Battery will not hold charge
MediumSymptoms: Short run time on the PC Unit or a module, battery-fault alarm.
Root cause: Aged battery pack or a charging-circuit fault.
Flow / delivery accuracy drift
MediumSymptoms: Delivered volume outside tolerance on the annual flow test.
Root cause: Worn pumping mechanism (Pump module) or drive (Syringe module).

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 and which module it is on.
- Look it up in Chapter 6 (Troubleshooting) of the Alaris Technical Service Manual.
- Use the maintenance software's diagnostics for that module.
- Follow the manual's corrective action - reseat / swap the module, cable or connector.
- Run PM, calibration and verification with the maintenance software after any repair.
Symptom: Occlusion / air-in-line on a Pump module
- Check the line for kinks, clamps and a closed roller clamp; check the patient IV site.
- Reload the set correctly, clearing all air.
- Confirm an approved set.
- Run the module diagnostics.
- Replace the set; refer the module if a sensor fault is indicated.

Synced live from the FDA openFDA API.
- RECALL
Under certain wireless network conditions a communication error can occur, which freezes the PC Unit screen, which may result in a delay of therapy. A delay of therapy may result in serious injury and/or death. CareFusion identified this potential risk associated with the Alaris PC unit model 8015 only (PC Unit) manufactured between December-2008 and September-2009.
