    Winters' Formula for Metabolic Acidosis Compensation

    Calculates the expected pCO₂ compensation in a purely metabolic acidosis.
    When to Use
    Why Use
    • A patient with a suspect pure metabolic acidosis.
    • A patient with a mixed acidosis to determine level of compensation.

    In a compensated state, a patient with a metabolic acidosis should be able to compensate by developing a respiratory alkalosis. Winters' Formula predicts this level of “appropriate” compensation.

    mEq/L
