Page 6: Introduction
Up to three liquid control lot numbers for each level of Liquid Quality Control (LQC) can be stored in the AVOXimeter 4000 and must be tagged to the stored or printed records. Cuvette lot numbers can also be tagged to the LQC records. The instruments can be configured so that only authorized operators can operate the system and that patient IDs can be entered for each test run. -
Page 7: Glossary Of Abbreviation Equivalents
1.39 is the amount of oxygen assumed to be carried by one gram of oxygenated hemoglobin (Hϋfner’s Number). Depending on your facility protocols, the Hϋfner’s Number stored in the AVOXimeter 4000 can be set at any value in the range of 1.30 to 1.39 (see page 30). Glossary of Abbreviation Equivalents In some cases, the display screen of the AVOXimeter 4000 does not show the most commonly used format for a specific constituent’s abbreviation. -

Need help?
Do you have a question about the AVOXimeter 4000 and is the answer not in the manual?
Questions and answers
I **** seeing fluctuation in the reading for the yellow filter. I have tried recalibrating the yellow filter and I **** still seeing sporadic readings
Fluctuation in the yellow filter readings on the Accriva Diagnostic AVOXimeter 4000 despite recalibration could be caused by contamination of the optical detector by blood or debris. The manual states that if quality control results are not acceptable, erroneous results occur, or error messages are displayed, contamination is the most likely cause and cannot be resolved by recalibration. It is recommended to consult the Troubleshooting section for further guidance.
