    Hyponatremia Correction Infusate Rate

    Input:
    Serum Na Change Per Hr
    Serum Na
    Water Fract Child (0.6)

    		 Adult Male (0.6)

    		 Adult Female (0.5)

    		 Elderly Male (0.5)

    		 Elderly Female (0.45)
    Weight
    IV Na 5% NaCl (855)

    		 3% NaCl (513)

    		 0.9% NaCl (Normal Saline) (154)

    		 Ringer Lactate (Includes 4 mEq/L K+) (134)
    IV K
    Results:
    Infusate Rate
    Serum Na Change Per Liter
     
    Decimal Precision:
    InfusateRate = (1000 * SerumNaChangePerHr * ((WaterFract * Weight) + 1)) / (IVNa + IVK - SerumNa)
    SerumNaChangePerLiter = (IVNa + IVK - SerumNa) / ((WaterFract * Weight) + 1)
