Medtronic Performer CPB
Medtronic · Model Performer CPB
Temperature monitoring using YSI Series 400 probes for 8 temperatures. Flow monitoring for the arterial line using a reusable Transonic ultrasonic flow probe. Oxygen saturation and hematocrit monitoring using an opto-electric sensor. Timers for the pump time, clamp time, and cardioplegia delivery times and intervals. Air Bubble Detection (ABD) of macro-air in the arterial circuit. Air Bubble Detection (ABD) of macro-air in the cardioplegia circuit. Active Air Removal (AAR) technology. Level detection utilizes a pair of level sensors to monitor changes in fluid or blood volume in the reservoirs. 12.1 In color touch screen display.
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
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.
Roller / centrifugal pump fault
HighSymptoms: A pump will not run at set flow, speed unstable, occlusion out of adjustment, flow-probe error.
Root cause: Worn roller-pump raceway / rollers, a centrifugal drive-motor / coupling fault, or a flow-probe fault.
Console / control-module fault
HighSymptoms: A pump module unresponsive, display errors, module not recognised by the console.
Root cause: Module electronics or the console-to-module link.
Battery / UPS fault
HighSymptoms: Short back-up run time, will not transfer cleanly on a power interruption.
Root cause: Aged battery / UPS pack.
Pressure / level / bubble-monitoring fault
MediumSymptoms: Pressure, reservoir-level or bubble-detector alarms implausible or not triggering.
Root cause: Transducer, level-sensor, or bubble-detector fault.
Heater-cooler / temperature fault
MediumSymptoms: Blood / cardioplegia temperature not tracking, heater-cooler alarm, flow fault.
Root cause: Heater-cooler pump / refrigeration or a temperature-probe 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.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and full PM
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: A pump will not run correctly
- Move the function to a spare pump module / mast position to isolate module vs console.
- Check the roller occlusion setting and inspect the raceway / rollers (roller pumps).
- Check the centrifugal drive coupling and flow probe.
- Verify flow against an independent flow probe.
- Replace the roller kit or drive components as isolated; a CPB console must pass a full functional check before clinical use.
Symptom: Monitoring alarm implausible or not triggering
- Verify each pressure channel against a reference.
- Test the level and bubble detectors per the service procedure.
- Reseat the sensor connectors.
- Calibrate the pressure channels.
- Replace a sensor that fails its functional test - these are safety systems.
