|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 He has his arterial blood withdrawn for acid-base analysis and the results show typical chronic respiratory alkalosis.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.
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|
