Use our Sodium Deficit Calculator to quickly determine the necessary sodium replacement for patients with hyponatremia. This essential clinical tool helps healthcare professionals estimate the mEq of sodium required, aiding in precise fluid and electrolyte management. Input current Na, desired Na, patient weight, and gender for an accurate calculation.
Formula:
Sodium Deficit (mEq) = (Desired Serum Na - Current Serum Na) × Total Body Water (TBW)
Where:
TBW (Total Body Water) for Males ≈ Weight (kg) × 0.6
TBW (Total Body Water) for Females ≈ Weight (kg) × 0.5
Current Serum Na: Current measured serum sodium level (mEq/L)
Desired Serum Na: Target serum sodium level (mEq/L)
Weight: Patient's body weight (kg)
