Many diagrams and slide bar functions add little to the reader’s understanding and some are difficult to decipher, with too many colours and axes
Specific causes for low and normal anion gap is discussed, however the well-known and arguably more important causes of a high AG are omitted.
No mention of base excess (some argue this is a more accurate marker of metabolic acid-base status than HCO3-) nor the Copenhagen approach
The physicochemical method (Stewart’s theory) isn’t included.
The bottom line
An overview of acid-base physiology that is a reasonable starting point for beginners. Unfortunately ABG Book doesn’t offer anything additional to most written, online or other app-based resources on this subject, has no clinical cases, and omits key concepts in advanced acid-base interpretation.
