A gradual increase in potassium, as may occur with chronic renal failure , may be better tolerated than a sudden increase. Slightly higher than normal potassium levels may be well tolerated by some persons with chronic renal failure. Tests Reflexes may be reduced or absent. Paralysis may be present or may occur. The pulse may be slow or irregular.
Serum potassium is high.
Hospitalization and close monitoring is required. The goal of acute treatment is to protect the body from the effects of hyperkalemia. This may include protective measures, shift of potassium into the intracellular fluid, and reduction of total body potassium. Emergency treatment is indicated if the potassium is very high, or if severe symptoms are present, including changes in the ECG . Intravenous calcium may be given to temporarily counteract the muscular and cardiac effects of hyperkalemia, including paralysis or cardiac arrhythmias .
