What is the acceptable potassium level range in mEq/L?

The acceptable potassium level range in mEq/L for a healthy adult is typically between 3.5 and 5.5. This range is critical because potassium plays a vital role in many physiological processes, including nerve function and muscle contraction, particularly in the heart. Maintaining potassium levels within this range is essential in hemodialysis patients, as they often face challenges in regulating electrolyte balance due to impaired kidney function. Deviations from this range can lead to serious complications, such as hyperkalemia (elevated potassium levels) which can result in dangerous cardiac arrhythmias. Thus, recognizing that 3.5 to 5.5 mEq/L is the standard for normal potassium levels highlights the importance of monitoring and managing potassium levels appropriately in patients undergoing hemodialysis.
