Contributor(s): Kathleen P Freeman, Elisa Mazzaferro, Rhea Morgan

Introduction

  • Definition: serum potassium concentration > 5.5 mEq/L.
  • Potassium balance is regulated by potassium intake, serum pH, serum insulin concentration, cell breakdown, and potassium excretion.
  • Acute increase in serum potassium > 7.5 mEq/L is life-threatening due to negative cardiac effects.
  • Serum potassium > 7.5 mEq/L is usually clinically significant.
