What is normal potassium balance
Approximately 98% of total body potassium resides inside cells, making it the most abundant cation in the intracellular fluid (ICF). The total body stores approximately 3000 mEq or more (approximately 50 to 70 mEq/kg body weight) of K + , with the skeletal muscle cells providing the biggest storage site for intracellular K + . ICF concentration of potassium is approximately 140 mEq/L compared to only 4 to 5 mEq/L in the extracellular fluid (ECF).
