                                Hypertonic saline is a crystalloid intravenous fluid with a sodium concentration higher than that of normal blood serum. While normal saline (0.9% NaCl) contains 154 mEq/L of sodium, the concentration in hypertonic saline can be significantly higher, reaching levels such as 513 mEq/L in a 3% solution. This makes it a powerful tool for shifting fluids in medical emergencies.
