What potassium level is indicative of hyperkalaemia?

Hyperkalaemia is a condition characterized by an elevated level of potassium in the blood. The normal range for serum potassium is typically between 3.5 and 5.0 mmol/L. When the potassium level surpasses this threshold, specifically exceeding 5.0 mmol/L, it is considered hyperkalaemia.

The significance of identifying hyperkalaemia lies in its potential health risks, such as cardiac arrhythmias, muscle weakness, and other serious complications. Monitoring potassium levels is crucial in clinical settings, particularly for patients with renal impairment, certain medications, or conditions that affect potassium balance. Therefore, a potassium level greater than 5.0 mmol/L is the clear indicator of hyperkalaemia, highlighting the necessity for prompt evaluation and intervention to prevent adverse effects.
