CorrectedSodiumCalculator

CorrectedSodiumCalculator calculator can be used to adjust measured serum sodium based on the patient's alkaline reserve (base excess). This is particularly useful in cases of respiratory or metabolic acidosis.

Calculation Formula

Corrected Sodium (mEq/L) = Measured Sodium + (1.6 × (Alkaline Reserve - 14)) / 2.5

Where:
- Measured Sodium: The measured serum sodium level
- Alkaline Reserve: The patient's serum base excess (mEq/L)

Result

When to Use This Calculator

This calculator is particularly useful in clinical settings when a patient's measured serum sodium appears low but may be falsely depressed due to acidosis. It helps adjust the sodium level to reflect what it would be in a normal metabolic state.

How It Works

The formula used in this calculator adjusts the measured sodium based on the patient's alkaline reserve (base excess). The base excess reflects the difference between the actual bicarbonate level and the expected bicarbonate level at a normal pH. A positive base excess indicates alkalosis, while a negative base excess indicates acidosis.

Example

For example, if a patient has a measured serum sodium of 135 mEq/L and a base excess of -5 mEq/L, the corrected sodium would be:

135 + (1.6 × (-5 - 14)) / 2.5 = 135 + (1.6 × (-19)) / 2.5 = 135 - 12.16 = 122.84 mEq/L

Important Notes

  • This calculator should be used as an aid to clinical judgment and not as a substitute for professional medical advice.
  • The formula used is based on standard clinical practice but may vary slightly in different institutions.
