IV calcium supplementation with 100-300 mg Ca2+ raises serum Ca2+ by 0.5 – 1.5 mEq
For acute but mild symptomatic hypocalcemia: 200-1000mg calcium chloride IV or 1-2g IV calcium gluconate over 2 hours
For severe hypocalcemia: 1g calcium chloride IV or 1-2g IV calcium gluconate IV over 10 minutes repeated q 60 min until symptoms resolve
