The appropriate dose of calcium chloride for hyperkalemia is 1to10 mL of 10% solution (equivalent to 27 mg Ca++/mL), administered no faster than I mL per minute, preferably diluted in an equal volume of sterile water for injection or normal saline solution (may be given undiluted during cardiac arrest), Calcium gluconate on the veins; however, it is 3 times less potent than calcium chloride. The dose for calcium gluconate is 3 to 30 mL of 100% solution (equivalent to 9.3 mg Ca++/mL), administered no faster than 2 mL per minute, diluted in normal saline solution or undiluted.
