[Calculation of the parameters of the acid-base balance with the aid of a small computer].

Abstract

The application and modification of a program published by Hardt (1972), Clin. Chem. 18,658--661) for the calculation of the true pCO2, the standard bicarbonate and the base excess are reported. 217 Determinations of a random patient sample were evaluated graphically, with the aid of a nomogram of Siggaard-Andersen, and mathematically with a computer program. There was good agreement between the two evaluation methods.
