1. Acute Respiratory Acidosis.

A young adult woman with chronic depression was found shortly after becoming unconscious as a result of taking an overdose of barbiturates. Acid-base results are typical of a pure respiratory acidosis. There has been no time for metabolic compensation to develop.

Acid-Base Zones

Classical Zones

The diagram shows the position of the principal zones. These zones are based on the review of the literature described by Schlichtig, Grogono, and Severinghaus. The arrows indicate typical acidosis and alkalosis. The labels in the black circles correspond to the legend in the table below.

Acidosis  Slope
AR   Acute Respiratory Acidosis:  Delta SBE = 0 
CR   Chronic Respiratory Acidosis:   Delta SBE = 0.4 x Delta PCO2
M   Metabolic Acidosis:  Delta PCO2 = 1.0 x Delta SBE
Blue Bar
Alkalosis  Slope
AR   Acute Respiratory Alkalosis:  Delta SBE = 0 
CR   Chronic Respiratory Alkalosis:     Delta SBE = 0.4 x Delta PCO2
M   Metabolic Alkalosis:   Delta PCO2 = 0.6 x Delta SBE
