Introduction: This Interactive Acid-Base Diagram is based on a paper written by Schlichtig R, Grogono AW, and Severinghaus JW. The red and blue zones on the right (click to enlarge) are based on this paper and accurately represent a group. However, a few individuals will lie outside each zone; so, always examine the patient carefully as well!
The Two Axes are the Respiratory Component (PCO2) and the Metabolic Component – Standard Base Excess (SBE). The lines for pH and Bicarbonate are also displayed but neither, alone, measures the Respiratory or the Metabolic Component.
The Sea Level Interactive Version is for use at or near Sea Level (say up to 1500 meters or 4920 ft) and demonstrates the relationships between pH, PCO2, and SBE.
The High Altitude Interactive Version is designed for use at higher altitudes but uses an Altitude Base Excess instead of SBE.
