WebJan 23, 2024 · Hyponatremia is defined as a serum sodium concentration of less than 135 mEq/L but can vary to some extent depending upon the set values of varied laboratories.[1] Hyponatremia is a common electrolyte … WebWhen treating hyponatremia, one must know how sodium distributes in the body in order to calculate how much sodium is needed to raise the serum sodium concentration by a desired amount. Most clinicians recognize that while sodium is primarily restricted to the extracellular space it appears to distribute over total body water. 1 However, the reason …
