Blood Gas Interpreter Calculator
Interpret arterial blood gas (ABG) results to determine acid-base status, compensation level, and oxygenation adequacy.
Inputs

mEq/L
mEq/L
Results
Acid-Base Status
1 (1=Normal, 2=Resp Acidosis, 3=Resp Alkalosis, 4=Met Acidosis, 5=Met Alkalosis, 6=Mixed)
Compensation
1 (1=Uncompensated, 2=Partial, 3=Full)
Oxygenation1 (1=Normal, 2=Mild Hypoxemia, 3=Moderate, 4=Severe)
How to Use This Calculator
- Enter arterial blood gas values: pH, PaCO2 (mmHg), HCO3 (mEq/L), and PaO2 (mmHg).
- Input FiO2 (fraction of inspired oxygen) to calculate the A-a gradient.
- Review the primary disorder classification (respiratory vs. metabolic, acidosis vs. alkalosis).
- Check for compensation: expected compensation ranges are calculated automatically.
- Use the interpretation notes to guide clinical correlation and management decisions.
