Overview
Hyperkalemia develops when blood potassium levels are more than 5.1meq/L. Hyperkalemia can be classified based on the potassium levels, duration of onset and the cause of hyperkalemia.
Classification
Hyperkalemia may be classified according to the potassium levels as:
- Mild- potassium levels between 5.1-6.0 mEq/L.
- Moderate- potassium levels between 6.2-7.0 mEq/L.
- Severe- potassium levels more than 7.0 mEq/L.
Hyperkalemia can be classified on the basis of duration as:
- Hyperacute- develops in a few hours, usually in tissue breakdown or parenteral potassium supplement.
- Acute-develops within 48 hours, could be due to acute kidney injury.
- Chronic-develops gradually, usually due to chronic diseases such as chronic kidney disease.
Hyperkalemia may be classified into several subtypes based on its cause:
- Excessive intake
- Transcellular shift
- Impaired elimination from body
- Hormone deficiency such as hypoaldosteronism
