TEJADA CIFUENTES, Francisco. Changes in potassium: Hypokalaemia. []. , 2, 3, pp.129-133. ISSN 2386-8201.

Hypokalaemia is a condition in which the level of potassium in the blood is below normal. Potassium, an essential electrolyte, aids in the conduction of nerve impulses and the contraction of skeletal and smooth muscles, including the heart muscle. It also facilitates cell membrane function and proper enzyme activity. Levels must be kept in a proper (homeostatic) balance for the maintenance of health. The normal concentration of potassium in the serum is in the range of 3.5-5.0 mEq/l. Hypokalaemia occurs when serum levels of potassium ions fall below 3.5 mEq/l. Hypokalaemia can result from two general conditions: either from an overall depletion in the body’s potassium or from excessive uptake of potassium by muscle from surrounding fluids.
