About this Calculator
This calculator is designed to assist veterinarians in creating a custom sodium-containing solution using the following formula:
Vx = [(C1 – C2) x V1]/(C3 – C2)
This formula helps determine the volume of a higher sodium concentration solution (e.g., hypertonic saline) needed to achieve a desired final sodium concentration in a baseline solution.
C1: Desired Na+ concentration in the final solution
C2: Current Na+ concentration in the baseline solution
V1: Desired volume of the final solution
C3: Na+ concentration in the hypertonic or other higher sodium solution
Vx: Volume of the hypertonic or higher Na+ solution to be added to the baseline crystalloid
