Calculation Formula

10% Potassium Chloride (mL) = (Set Value - Measured Value) × Weight (kg) × 0.3 / 1.34

Note: The result of this formula does not include physiological needs. The daily physiological requirement for adults is: 10% Potassium Chloride 60-70 mL.

Hypokalemia

Mild Potassium Deficiency: Serum potassium 3 ~ 3.5 mmol/L, supplement 100 mmol, equivalent to 8g of potassium chloride (including physiological needs)

Moderate Potassium Deficiency: Serum potassium 2.5 ~ 3 mmol/L, supplement 300 mmol, equivalent to 24g of potassium chloride (including physiological needs)

Severe Potassium Deficiency: Serum potassium 2 ~ 2.5 mmol/L, supplement 500 mmol, equivalent to 40g of potassium chloride (including physiological needs)

Normal adult daily physiological requirement: Potassium 3~4g (converted to potassium chloride: 6~7g or 10% Potassium Chloride 60-70 mL)
