Question: is this a 2) strong advice, 1) weak advice 0) no advice?

The accuracy and precision of the calibrated CDI estimates, gas or ABL calibration, for pH, pCO2, and pO2 were not significantly different from the ABL values, and thus the calibrated CDI can be a valuable tool for the perfusionist in maintaining a stable and physiologically correct acid-base balance during CPB.
