Sodium Deficit Calculator
This estimates sodium needed to raise serum sodium. Final fluid choice and correction rate depend on symptoms, volume status, chronicity, and local protocol.
References and Safety Notes
The sodium deficit formula estimates sodium required to raise serum sodium by a selected target amount. Do not use it as an automatic infusion order; correction rate and fluid choice depend on symptoms, chronicity, volume status, and repeat sodium monitoring.
