|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.
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.
|AR||Acute Respiratory Acidosis:||SBE = 0|
|CR||Chronic Respiratory Acidosis:||SBE = 0.4 x PCO2|
|M||Metabolic Acidosis:||PCO2 = 1.0 x SBE|
|AR||Acute Respiratory Alkalosis:||SBE = 0|
|CR||Chronic Respiratory Alkalosis:||SBE = 0.4 x PCO2|
|M||Metabolic Alkalosis:||PCO2 = 0.6 x SBE|
