Avoximeter Whole Blood CO-Oximeter
Avoximeter Whole Blood CO-Oximeter System - Instrument (Loaner)
Intended use: A mains electricity (AC-powered) instrument, which may include internal rechargeable batteries, intended to be used by health professionals at the point-of-care, and often in the laboratory, for the quantitative in vitro measurement of oxygen saturation, haemoglobin derivatives and other calculated haemoximetry parameters in a whole blood specimen. Measurements may include haemoglobin oxygen saturation (SpO2), arterial oxygen saturation (SaO2), blood oxygen content/capacity, and haemoglobin forms such as oxyhaemoglobin (O2Hb), deoxyhaemoglobin (HHb) or reduced haemoglobin (RHb), carboxy-haemoglobin (COHb), methaemoglobin (MetHb), sulfhaemoglobin (SHb), and total haemoglobin (totHb).
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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.
Inaccurate / questionable oximetry results
HighSymptoms: tHb, O2Hb, COHb or MetHb values implausible, QC out of range.
Root cause: Dirty or scratched cuvette optics, an air bubble / short sample in the cuvette, lamp aging, or calibration drift.
Lamp / optical source failure
MediumSymptoms: Low signal, will not read, lamp / reference-intensity warning.
Root cause: Optical source at end of life.
Cuvette handling / detection fault
MediumSymptoms: Bubble or short-sample errors, cuvette not detected.
Root cause: Air in the microcuvette, a worn cuvette, or a cuvette-detect sensor fault.
Battery / power fault
LowSymptoms: Will not power on, short battery life (portable models).
Root cause: Depleted or aged battery.

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.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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: Results inaccurate / QC fails
- Run the QC / calibration-verification standard and compare to the assigned values.
- Clean the cuvette optics / detection window.
- Fill a fresh microcuvette avoiding bubbles.
- Replace the lamp if the reference intensity is low.
- Re-verify with QC before reporting patient results.
Symptom: Bubble / short-sample errors
- Refill the cuvette avoiding air.
- Inspect the cuvette for scratches or residue.
- Use a fresh cuvette.
- Confirm the correct sample volume.
- Re-run the sample.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Values used to calibrate whole blood oximeter instruments were observed to be higher than normal, which may result in incorrect patient results where oxygen levels are higher than actual results, which may lead to patient care mismanagement requiring medical intervention.
