Hypertonic Saline Preparation Calculator (Making 3% Saline)

This calculator helps determine the final NaCl concentration when mixing two saline solutions. Especially useful for preparing 3% saline for hyponatremia correction.

Solution A: [e.g., Normal Saline]

* Normal saline is 0.9% NaCl solution
Solution B: [e.g., Hypertonic Saline]



※ How to Easily Make 3% Saline (using 11.7% NaCl)
① Remove 100 mL from 500 mL normal saline (leave 400 mL)
② Add 100 mL of 11.7% NaCl solution

※ How to Easily Make 3% Saline (using 10% NaCl)
① Remove 100 mL from 500 mL normal saline (leave 400 mL)
② Add 120 mL of 10% NaCl solution
