Hyperkalemia is an elevated level of potassium (K +) in the blood. [1] Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels above 5.5 mmol/L defined as hyperkalemia.
As an example, assume that 22.45±0.03 cm 3 of the sodium hydroxide solution reacts with 781.4±0.1 mg of potassium hydrogen iodate. As the equivalent weight of potassium hydrogen iodate is 389.92 g, the measured mass is 2.004 milliequivalents. The concentration of the sodium hydroxide solution is therefore 2.004 meq/0.02245 L = 89.3 meq/L.
20 mEq (781 mg) potassium from potassium gluconate (4680 mg), or potassium citrate (2040 mg), mixed with a half-cup (1.12 dL) water, taken two to four times a day, may be used on a daily basis. [ 31 ] [ 32 ]
Potassium resides mainly inside the cells of the body, so its concentration in the blood can range anywhere from 3.5 mEq/L to 5 mEq/L. [14] The kidneys are responsible for excreting the majority of potassium from the body. [14] This means their function is crucial for maintaining a proper balance of potassium in the blood stream.
Because of the risk of small-bowel lesions, the US Food and Drug Administration (FDA) requires some potassium salts containing more than 99 mg (about 1.3 mEq) to be labeled with a warning, [14] while recommending an adult daily intake of 4700 mg (about 63 mEq).

Acutely, repletion with 10 mEq of potassium is typically expected to raise serum potassium by 0.1 mEq/L immediately after administration. However, for those with chronic hypokalemia, repletion takes time due to tissue redistribution. For example, correction by 1 mEq/L can take more than 1000 mEq of potassium over many days. [6]
