5. Metabolic Acidosis.

A middle-aged man with insulin-dependent diabetes develops an abscess on his leg. He makes no adjustment in his insulin dosage and develops hyperglycemia and keto-acidosis. Acid-base results are typical of a metabolic acidosis. In response to the acidosis he is ventilating more than usual to produce typical partial compensation - respiratory alkalosis.

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:	SBE = 0
CR	Chronic Respiratory Acidosis:	SBE = 0.4 x PCO₂
M	Metabolic Acidosis:	PCO₂ = 1.0 x SBE

Alkalosis		Slope
AR	Acute Respiratory Alkalosis:	SBE = 0
CR	Chronic Respiratory Alkalosis:	SBE = 0.4 x PCO₂
M	Metabolic Alkalosis:	PCO₂ = 0.6 x SBE
