A nomogram is presented, based on Kintner's acid-base nomogram, for simpler evaluation of clinical states based on acid-base variables. The complicated line graph for pH values of the original nomogram has been replaced by a simple H-shaped diagram that immediately signals the clinical state. Left and right scales are respiratory and metabolic ordinates, respectively, and each is subdivided into acidotic and alkalotic regions. The clinical state is found by a "balance line" that connects the deviations from normal metabolic and respiratory values. The larger deviation signals the primary cause of imbalance; the smaller one reflects the degree of compensation for the primary effect.
