Abbott i-STAT portable Analyser
Abbott · Model i-STAT portable Analyser
Stores up to 50 patient records. On-screen viewing of test results. Transmission of records to a data management system. System prompts users step by step through the testing process. Operator and patient information can be entered via barcode scanner. Operator lockout prevents unauthorized users from performing or viewing test results. Test results are uploaded automatically when the i-STAT handheld is placed in a downloader.
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.
Sensor / electrode fault or drift
HighSymptoms: pH, pCO2, pO2, electrolyte, glucose / lactate or CO-oximetry results flagged, QC fails, stability / response errors.
Root cause: An electrode / membrane at end of life, an air bubble or protein in the measuring path, or a calibration fault.
Sample-path / inlet clog or clot
MediumSymptoms: Sample not aspirated, clot detected, inlet / preheater alarm.
Root cause: Clot in the inlet probe / preheater, or a worn inlet gasket.
Solution / cartridge / gas / waste fault
MediumSymptoms: Reagent-empty, gas-supply or waste-full alarm, calibration fails.
Root cause: Empty or expired solution pack / cartridge, an empty / expired gas cylinder, or a full waste container.
Pump / valve / pneumatic fault
MediumSymptoms: Poor sample transport, calibration or rinse failures, pressure alarms.
Root cause: Worn peristaltic pump tubing, a pinch-valve fault, or a pneumatic-pressure fault.
CO-oximetry / optical fault
MediumSymptoms: tHb, sO2 or dyshaemoglobin results implausible, optics / lamp error.
Root cause: Optics contamination, a lamp fault, or the haemolyser.

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: Sensor flagged or QC fails
- Run the relevant calibration and check the sensor / electrode status screen.
- De-bubble / rinse the measuring path and check for protein deposits.
- Replace an electrode / membrane at end of life or that fails calibration.
- Confirm the solution pack and calibration gas are in date and not empty.
- Re-run QC at the relevant levels before releasing results.
Symptom: Sample not aspirated / clot
- Run the inlet / preheater clot-removal or rinse routine.
- Inspect the inlet probe and gasket.
- Replace the inlet gasket or probe.
- Confirm free sample aspiration with a QC sample.
- Replace worn pump tubing if transport is still poor.
