[Determination of acid-base parameters by means of programmable pocket calculators (author's transl)].

The possibility to calculate parameters of acid-base status derived by common laboratory devices without built-in computers is described. The calculation is carried out faster and more exactly than it is possible by nomograms, which is especially suitable when a great quantity of dates occurs. The number of programmable steps in some inexpensive pocket calculators is sufficient for this purpose; this type of "microcomputers" offers advantages of economy and small size so that calculations can be carried out immediately at the site where measurements are taken.
