Elevated HCO₃
March 4th, 2023
Overview
An elevated bicarbonate level greater than 26 suggests the presence of a metabolic process - either primary (metabolic alkalosis) or secondary (compensation for respiratory acidosis).
Interpretation
- Elevated pH with elevated HCO₃ - suggests metabolic alkalosis
- Reduced pH with elevated HCO₃ and elevated PCO₂ - suggests metabolic compensation for chronic respiratory acidosis
- Normal pH with elevated HCO₃ and elevated PCO₂ - suggests mixed metabolic alkalosis-respiratory acidosis
