Hypokalemia is a common and potentially life-threatening electrolyte disturbance.
This article reviews normal potassium homeostasis and transcellular potassium movement.
In addition, extrarenal and renal causes of hypokalemia are discussed. The authors
conclude this article with a simple approach to evaluation and management of hypokalemia
in the intensive care unit setting.
