Abstract

Understanding the principles of acid-base physiology at the bedside is an important challenge for the intensive care professional. The last 20 years showed a particularly interest in this field and in the last five years was created a new model of acid-base balance: the physical-chemical quantitative model. A succession of three groups of equations is available now to properly describe this process: Stewart theory, Figge-Fencl theory and Wooten theory.
The aim of the paper is to present these models and some links with the old descriptive and semi-quantitative models for Romanian reader. The main definitions for: strong ions difference (SID), strong ions gap (SIG), ATOT, buffer value () of plasma, base excess (BE), standard base excess (SBE), anionic gap (AG) and pH are presented.

Key words: Strong ions difference, strong ions gap, ATOT, buffer value () of plasma, base excess, standard base excess, anionic gap, pH, Stewart theory, acid-base balance
