In the hypo-osmolar state (serum osmolality less than 280 mOsm/kg), urine osmolality is used to determine whether water excretion is normal or impaired.
WebHypernatremia is defined as a serum sodium concentration exceeding 145 mEq/L. Sodium is the most important osmotically active particle in the extracellular space and closely linked to the body's fluid balance. An increase in the serum sodium concentration is most often due to a free water deficit caused by excessive fluid loss (e.g., diarrhea/vomiting, sweating, … WebHypotonicity, in turn, can lead to cerebral edema, a potentially life-threatening complication. 4 Hypotonic hyponatremia can be associated, however, with normal or even high serum osmolality if ...
