Mild or moderate symptoms

 • Goal: Normalization

 • Fluid restriction alone if etiology rapidly reversible. Otherwise, hypertonic saline at 1 mL/kg/h until substantial normalization

Chronic Hypotonic Hyponatremia (duration known to be >48h or duration uncertain)

Severe, moderate, or mild symptoms

 • Goal: 4-6 mEq/L in 24h 

 • Limit: 8 mEq/L in any 24h period
