Web19 feb. 2024 · Hyperkalemia is defined as a serum or plasma potassium level above the upper limits of normal, usually greater than 5.0 mEq/L to 5.5 mEq/L. While mild hyperkalemia is usually asymptomatic, high potassium levels may cause life-threatening cardiac arrhythmias, muscle weakness, or paralysis. WebNormal potassium levels are generally between 3.5 and 5.5 mEq/L. Definitions can vary by weight, but most define hyperkalemia as >6 mEq/L in newborns. Hyperkalemia is common in extremely low birthweight infants. This is the most serious of electrolyte abnormalities because it can cause fatal arrhythmias.
