Sodium Correction Rate (Correction rate per 24 h)

Sodium Correction Rate: calculated with the published clinical method, with result interpretation. A reference tool that does not replace a doctor's advice.

ℹ Reference calculation based on the published method. It does not replace a clinical examination or a doctor's decision.

Formula & example

The calculator computes Correction rate per 24 h (mmol/L) from parameters:

Initial sodium (mmol/L)
Current sodium (mmol/L)
Time elapsed (h)
High risk: alcoholism, malnutrition, hypokalemia, Na ≤ 105 (1 = yes)

Example 1

Initial sodium = 118 mmol/L, Current sodium = 124 mmol/L, Time elapsed = 12 h, High risk: alcoholism, malnutrition, hypokalemia, Na ≤ 105 (1 = yes) = 0

→ Correction rate per 24 h: 12 mmol/L

Example 2 (×1.5)

Initial sodium = 177 mmol/L, Current sodium = 186 mmol/L, Time elapsed = 18 h, High risk: alcoholism, malnutrition, hypokalemia, Na ≤ 105 (1 = yes) = 0

→ Correction rate per 24 h: 12 mmol/L

FAQ

How is BMI calculated?

BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.

Is BMI accurate for everyone?

No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.

What are the BMI categories?

Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.

What is a better measure than BMI?

Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
