Abstract
The potassium concentration within human cells is approximately 70 mmol per liter, yet extracellular potassium concentration is normally 3.5 to 5.0 mmol per liter.(1),(2) Hyperkalemia is defined as a plasma potassium level of greater than 5.0 mmol per liter. Mild hyperkalemia (>5.0 to 5.9 mmol per liter) requires monitoring and the avoidance of a high intake of potassium and, often, changing therapies that may be increasing potassium levels. Greater degrees of hyperkalemia - potassium levels of 6.0 to 7.0 mmol per liter (moderate hyperkalemia) and more than 7.0 mmol per liter (marked hyperkalemia) - may lead to cardiac arrhythmias . . .
