Calcium replacement (gluconate / chloride + elemental Ca)

IV calcium product math (AHA ACLS 2020, USP labeling): elemental calcium (mg and mEq) delivered by a gluconate or chloride dose, the equivalent dose of the other salt, and indication text.

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).

How this is calculated

AHA ACLS 2020 (Panchal, Circulation 2020;142:S366) for hyperkalemia membrane-stabilization calcium; elemental calcium per USP/product labeling: calcium chloride 10% ~273 mg (13.6 mEq)/g, gluconate 10% ~93 mg (4.65 mEq)/g, so chloride carries ~3x the elemental calcium per gram. Read the source ↗
