Baxter Gambro AK200 ULTRA S
Baxter International · Model Gambro AK200 ULTRA S
The AK 200 ULTRATM S machine offers on-line options of hemodialysis, hemodiafiltration and hemofiltration. Specifically designed for on-line HDF/HF treatments, this machine with ULTRACONTROL provides unique high convective volume in a smooth way. This is true even in the most challenging setup: HDF post-dilution with high hematocrit level patients. Thanks to the three-barrier filtration concept, the AK 200 ULTRA S ensures optimal fluid quality throughout any treatment. [b][i]This product is not available for sale in the U.S.[/i][/b]
Key tips
- ·Conductivity and water-quality checks are non-negotiable before every shift - dialysate chemistry errors are a direct patient-harm mechanism.
- ·Confirm disinfection cycle completion, never assume it, after every use.
- ·Treat a blood-leak detector fault as real until proven otherwise - never silence and continue.
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.
Conductivity / temperature / dialysate-prep alarm
HighSymptoms: Conductivity or temperature out of range, dialysate-preparation alarm, treatment will not start.
Root cause: Concentrate connection / supply, a heater fault, a conductivity-cell fault, or a proportioning-pump / valve fault.
Blood or dialysate pump fault
MediumSymptoms: Pump will not run at set speed, occlusion or flow alarms, tubing walking in the raceway.
Root cause: Worn pump rotor / rollers or a motor / control fault.
Pressure-monitoring / air-detector fault
MediumSymptoms: Venous / arterial / TMP pressure implausible, air-detector false alarms or fails to detect.
Root cause: Transducer-protector wetting, a pressure-sensor fault, or an air-detector fault.
UF / balancing-chamber fault
MediumSymptoms: Fluid-balance / UF alarms, weight loss inaccurate, balancing-chamber leak.
Root cause: Balancing-chamber diaphragm / valve wear or a flow-sensor fault.
Disinfection / rinse fault
MediumSymptoms: Heat or chemical disinfection will not complete, residual disinfectant test fails.
Root cause: Heater, a dosing / rinse valve, or a conductivity-verification fault.

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: Conductivity or temperature alarm
- Confirm the concentrate is connected, correct and not empty.
- Verify dialysate conductivity and temperature with independent calibrated meters.
- Check / calibrate the conductivity cell and temperature sensor.
- Inspect the proportioning pumps / valves and de-air the hydraulics.
- Do not treat until conductivity and temperature are verified in range.
Symptom: Pump or pressure fault
- Inspect the pump rotor and rollers for wear and correct occlusion.
- Reseat the tubing segment in the raceway.
- Check the pressure transducers and protectors for wetting.
- Calibrate the pressure channels.
- Replace the rotor / rollers or a faulty sensor as isolated.
