Base excess significantly corrected for the variations in apparent dissociation constant for human blood gas testing.

ABSTRACT

We introduce a pragmatic approach towards the corrected Base Excess (BE) by including the large variability of the apparent dissociation constant pK' in non-logarithmic form in Henderson-Hasselbach bicarbonate ion equilibria thereby resulting in a significant correction both in calculated bicarbonate ion concentration and BE at 37 degrees C.
