Calcium can be administered IV to patients who present with symptomatic hypotension or heart block, as follows [5, 6, 7] :

  • Calcium gluconate, 30 mL of 10% solution, infused over 10-15 minutes in adults
  • Recommended pediatric dose of calcium gluconate is 60 mg/kg, with a maximum dose of 1 g [8]
  • Calcium chloride (1-4 g) is preferably given via central line, slowly
