Calcium and Phosphate Concentrations in a PN Bag
Calcium (mEq/L) and phosphate (mmol/L) concentrations in a PN bag, their sum, and the amino acid percent.

Example
- Final volume
- 1000 mL
- Calcium entered as mEq (mEq) or mL of calcium gluconate 10%
- mEq of calcium
- Calcium amount
- 10
- Phosphate entered as mmol (mmol)
- mmol of phosphate
- Phosphate amount
- 15
- Your limit is a maximum calcium at this phosphate (max-calcium) or a maximum sum
- Maximum sum: calcium mEq/L + phosphate mmol/L
- Your limit, from your own curve or software
- 30
Result: Calcium 10 mEq/L and phosphate 15 mmol/L (sum 25): at or under your limit of 30 for the sum.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Final volume
- Calcium entered as mEq (mEq) or mL of calcium gluconate 10% (mL-gluconate)
- Calcium amount
- Phosphate entered as mmol (mmol), mL of potassium phosphates (mL-kphos) or mL of sodium phosphates (mL-naphos)
- Phosphate amount
- Amino acids (optional)
- Volume at the point of lowest dilution (optional)
- Your limit is a maximum calcium at this phosphate (max-calcium) or a maximum sum (sum)
The other 3 fields
- Your limit, from your own curve or software
- Calcium mEq per mL from the vial (only if the label figure is withheld)
- Phosphate mmol per mL from the vial (only if the label figure is withheld)
