Hyponatremia in hemodialysis patients

Formula 1: Increase in serum sodium at the end of hemodialysis session

Formula 2: Blood flow rate (Qb) needed for a slow rise in serum sodium

Formula 3: Volume of D5W needed to slow down the rate of serum sodium rise

Hypernatremia in hemodialysis patients

Formula 4: Volume of 3% saline needed to slow down rapid the rate of serum sodium decline

Hyponatremia in CRRT

Formula 5: Volume of D5W needed to slow the rate of serum sodium rise in CVVH

Formula 6: Volume of D5W needed to slow the rate of serum sodium rise in CVVHDF

Formula 7: Increase in serum na after 1 hour of CRRT

Hypernatremia in CRRT

Formula 8: Volume of 3% saline to slow the decline in serum sodium in CVVHDF

Formula 9: Decrease in serum sodium after 1 hour of CRRT
