When confronted with a situation where a blood gas analyzer is operating correctly but the control parameters fall outside acceptable ranges, the first step should be to verify the control data. This involves checking that the control solutions used are still within date and have been stored correctly, as well as ensuring that the measurements made by the analyzer are accurate and reliable by comparing them against established values.

Verifying control data can help to rule out issues related to the quality of the control solutions or previous calibration errors. It is essential to confirm that the problem is not stemming from the control materials themselves, which could lead to misleading assessments about the analyzer's performance.

Additionally, addressing control data verification first allows for a more efficient diagnostic process. If the control data is verified as correct and within range, then steps like cleaning the electrodes, replacing solutions, or more intensive cleaning of the sample path can be considered. However, if the control data indicates a problem, it may direct technicians to specific corrective measures more promptly.
