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.

Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
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.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Potassium channel Kv1.2, structure in a membrane-like environment. Calculated hydrocarbon boundaries of the lipid bilayer are indicated by red and blue lines. Potassium channels are the most widely distributed type of ion channel found in virtually all organisms. [1] They form potassium-selective pores that span cell membranes.
BK channels (big potassium), are large conductance calcium-activated potassium channels, [1] also known as Maxi-K, slo1, or Kca1.1. BK channels are voltage-gated potassium channels that conduct large amounts of potassium ions (K + ) across the cell membrane , hence their name, big potassium .
Hypercalcemia, also spelled hypercalcaemia, is a high calcium (Ca 2+) level in the blood serum. [1] [3] The normal range is 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), with levels greater than 2.6 mmol/L defined as hypercalcemia.
