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 aldosterone.
