The appropriate dose of calcium chloride for hyperkalemia is 1to10 mL of 10% solution (equivalent to 27 mg Ca++/mL), administered no faster than 1mL 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.
