NOTICE: The formula is different from previous Radiometer analyzers. The
calculation is done in accordance with NCCLS (CLSI)-approved guidelines [24].
However, since it is assumed that the previous method [14] is a better model,
the previous range checks are retained (no values displayed outside ±50
mmol/L and values tagged with "?" outside the range of ±30 mmol/L).
The change corresponds to less than 0.6 mmol/L in the reference ranges for pH,
pCO
2
and ctHb.

If ctHb is not measured or keyed in, the default value will be used.
If sO
