Sodium Deficit in Hyponatremia
Calculates sodium quantity missing in hyponatremia.
Remember not to correct too rapidly to avoid central pontine myelinolysis!
You can use the hyponatremia correction rate calculator to pick an appropriate fluid and volume as well.
Sodium Deficit = Total Body Water * Normal Wt in kg * (Desired Na - Pt's Na) (TBW = 0.6 if male and 0.5 if female)
