Acid-base balance nomogram--a Boston-Copenhagen detente

Anesthesiology. 1976 Nov;45(5):539-41.

Abstract

Quantitation of actual and expected complete compensation for chronic hypercapnia in man is facilitated by addition of data of Brackett et al. in the form of an arc to the Siggaard-Andersen alignment nomogram. Percentage of compensation is defined as 100 times the ratio of observed to predicted (fully compensated) base excess at the patient's PCO2. Extracellular fluid base excess, defined as BE3, is estimated from a 3-g hemoglobin line added to the nomogram.
