To ensure that the output of a blood gas analyzer is both accurate and linear across the range of measured values, a calibration procedure must measure what?

Question

Quizplus · Accepted Answer

To ensure both accuracy and linearity, a blood gas analyzer must be calibrated using parameters with known input values at two different points. This involves measuring the analyzer's response to samples with known concentrations or values of the parameter being measured at two different points, such as at the low and high end of the range of values the analyzer can measure. By comparing the measured values to the known values, the analyzer can be calibrated to ensure accurate and linear output across the entire range of values.
