Sodium_deficit_in_hyponatremia v.1
The calculated sodium deficit in patients with hyponatremia.
To calculate sodium deficit in patients with hyponatremia.
Use to calculate the sodium deficit in order to note the quantity missing in hyponatremia patients. Formula: Sodium deficit = total body water × (desired Na - pt's Na) For adults, total body water (TBW) is calculated using the Watson equation: 1. Men: TBW, liters = 2.447 – 0.09516 × age, years + 0.1074 × height, cm + 0.3362 × weight, kg 2. Women: TBW, liters = -2.097 + 0.1069 × height, cm + 0.2466 × weight, kg For children, TBW = 0.6 × weight, kg
