Overview
Hyperkalemia develops when blood potassium levels are more than 5.1meq/L.Hyperkalemia can be classified based on the potassium levelas as mild,moderate and severe.It is also classified on basis of duration as hyperacute,acute and chronic.Causes of hyperkalemia can also be used to classify.
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
- 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.
