Winter's formula
Expected PaCO2 during metabolic acidosis: 1.5 × HCO3 + 8, plus or minus 2.
Result
Fill the inputs to compute.
- Interpretation
- Measured PaCO2 above the range adds a respiratory acidosis; below it adds a respiratory alkalosis.
- Limitations
- Applies to metabolic acidosis only; other disorders have their own compensation rules.
