Potassium is the main cation in cells, with a concentration of 150-160mmol/L, while the main cation outside cells is sodium ion, and the serum potassium concentration is only 3.5-5.0mmol/L. The body mainly relies on Na-K-ATPase on the cell membrane to maintain the concentration difference between K and Na in cells. The acid-base balance in the body has an impact on potassium metabolism. For example, when acidosis occurs, H enters the cell. In order to maintain the potential difference between the inside and outside of the cell, K is released outside the cell, causing or aggravating hyperkalemia. Metabolic disorders can also affect acid-base balance. The normal potassium ion concentration and concentration difference inside and outside the cell are closely related to some important functions of the cell, including maintaining carbohydrate metabolism, glycogen storage, protein metabolism, intracellular osmotic pressure and acid-base balance, and myocardial excitability.
