Century Heart & Lung Heart Lung Machine
Century Heart & Lung · Model Heart Lung Machine
Heart-Lung Bypass Unit [b]Functional Advancements[/b] The Heart Lung Machine's minimal footprint takes up very little floor space while keeping components easily accessible. The pumps lift and lock securely in the upright position. Cable connections from the back of the system are located underneath, enabling easy access and fast troubleshooting during a case. Spill protection features make clean up easier. Cabling located under the pump is kept neatly organized and protected. Individual pump faces clean up fast because most knobs and crevices have been liminated from the design. Overhangs help direct spills away from the Heart Lung Machine and liquids that splash on the system are collected by a tray and drip gutters. [b]Precision Controls[/b] The roller pump display on the Century Heart Lung Machine is simple and easy to read. The system's computer will automatically calibrate for flow. Simply enter the tubing size, and it will perform the calculations even for dual-tube cardioplegia ratios or variable size tubing. The Century features exclusive rapid/fine flow control knobs. They ensure precise perfusion control in low flow conditions, important factors during cardioplegia and neonatal surgery. The computer's cardioplegia delivery system can track last volume delivered, total volume delivered, and time since last delivery. The Century's computer also has important built in safety features including the AEPS (Air Emboli Protection System); reservoir level sensor; and pressure regulation, which protects against accidental occlusion. [b]Built to Last[/b] The Century Heart Lung Machine has been built with the materials and craftsmanship that make this a durable and dependable piece of equipment. Solid construction makes the system easy to move and the rigid push bar doubles as a front mast for mounting a vaporizer or blender. Castersare protected from spills, roll easier and lock securely. Also exclusive to the Century Heart Lung Machine, is the 100% stainless steel chassis that will provide years of problem free performance.

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.
