4. Chronic Respiratory Alkalosis.

An anesthesiologist relocates to high altitude. He has his arterial blood withdrawn for acid-base analysis and the results show typical chronic respiratory alkalosis. In response he has developed compensatory metabolic acidosis. This compensation usually takes some weeks to fully develop. When this has occurred, some people demonstrate complete compensation with a pH close to 7.4.

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
