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
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.
Oxygenator / heat exchanger fault
HighSymptoms: Poor gas exchange or temperature control.
Root cause: Oxygenator membrane fouling or heat-exchanger leak.
Roller / centrifugal pump head wear
HighSymptoms: Inaccurate flow, unusual noise from the pump head.
Root cause: Raceway wear or centrifugal rotor bearing wear.
Level / bubble sensor fault
HighSymptoms: False or missed air-in-line/level alarm.
Root cause: Ultrasonic sensor drift or dirty optics.
Console display / control fault
MediumSymptoms: Console freeze or loss of readouts mid-case.
Root cause: Main control board or display module 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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Oxygenator / heat exchanger fault
- Confirm the presentation - typically poor gas exchange or temperature control - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: oxygenator membrane fouling or heat-exchanger leak.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the pump head / raceway 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.
