Pseudohyperkalemia, a rise in the amount of potassium that occurs due to excessive leakage of potassium from cells, during or after blood is drawn
Blood test, usually performed for another reason
Calcium, as calcium chloride, calcium gluconate, or [calcium] resonium, to increase the threshold potential, thus restoring normal gradient between the threshold potential and the resting membrane potential, which is elevated abnormally in hyperkalemia
Removal of excess potassium is usually necessary, by:
Stimulating urine production
What can you do about high potassium in blood?
You can give calcium. Or you can also remove extra potassium, through increasing urination, and using an artificial kidney.
