Custom Saline Calculator

New custom sodium calculator released... This new tool was created based on important feedback from Dr. Shaw. Minor changes to the original calc were completed as well.

".....The hypertonic saline calculator still did not meet what I was looking for, but I understand one calculator cannot fit every need and the inherent risks and liability with administration of 3% saline.

If I had the "perfect" calculator... I would want fields for:
starting Na
desired ending Na
choice of saline concentration 0.9% or 3%

This would provide how many ml of either 3% or 0.9% saline required to change the sodium to the desired value. This could further be defined if a meq/hr choice was provided of 0.5 meq/hr or 1 to give a infusion rate...."
