Calcium replacement (gluconate / chloride + elemental Ca)
IV calcium product math: elemental calcium (mg and mEq) delivered by a gluconate or chloride dose, and the equivalent dose of the other salt.

Example
- Calcium product
- Calcium gluconate 10%
- Dose
- 1 g
- Indication
- Hyperkalemia (membrane stabilization)
Result: 1 g calcium gluconate 10% (10 mL) = 93 mg (4.6 mEq) elemental calcium = 0.34 g calcium chloride 10% (3.4 mL).
The tool opens with these values already filled in. Replace them with your own.

Citation
AHA ACLS 2020 (Panchal, Circulation 2020;142:S366) for hyperkalemia calcium. Elemental calcium, dose ranges and maximum rates: the calcium gluconate (9.3 mg/mL) and calcium chloride (27 mg/mL) injection labels, so chloride carries about 3x the calcium per gram.
