What is the normal range for potassium levels in the blood?

The normal range for potassium levels in the blood is typically between 3.5 and 5.5 milliequivalents per liter (mEq/L). Potassium is a crucial electrolyte that plays a vital role in various physiological processes, including nerve conduction, muscle contraction, and maintaining fluid balance. Maintaining potassium levels within this normal range is essential, as both low (hypokalemia) and high (hyperkalemia) levels can lead to serious health issues, such as cardiac arrhythmias.

The range given covers the majority of healthy individuals and aligns with standard laboratory criteria. Thus, recognizing the normal potassium range is particularly important within the context of hemodialysis, where patients often face challenges in maintaining appropriate electrolyte balances due to their treatment and underlying conditions. Understanding this range helps technicians monitor and manage patients effectively during their dialysis sessions.
