Sodium chloride is an electrolyte supplement. Sodium and chloride are important electrolytes in the body, mainly present in extracellular fluid, and play a very important role in maintaining normal blood and extracellular fluid volume and osmotic pressure. The normal serum sodium concentration is 135-145mmol/L, accounting for 92% of plasma cations and 90% of total osmotic pressure, so the amount of plasma sodium plays a decisive role in osmotic pressure. The normal serum chloride concentration is 98-106mmol/L. Sodium and chloride ions in the human body are mainly regulated by the hypothalamus, posterior pituitary and kidneys to maintain the stability of body fluid volume and osmotic pressure.

Converted into bicarbonate ions in the body to regulate acid-base balance and maintain normal physiological functions; lactate ions can correct metabolic acidosis and allow potassium ions to enter cells from blood and extracellular fluid.

Sodium is the most important cation in extracellular fluid and is the main substance for maintaining constant body fluid osmotic pressure and extracellular volume.

Potassium is the main intracellular cation and plays an important role in maintaining normal neuromuscular excitability.

Calcium ions act as second messengers in cells and are closely related to many functions of the body.

Potassium is the main cation in cells, with a concentration of 150-160 mmol/L, while the main cation outside cells is sodium ions, and the serum potassium concentration is only 3.5-5.0 mmol/L. The body mainly relies on Na+-K+ ATPase on the cell membrane to maintain the difference in K+ and Na+ concentrations inside and outside 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 inside and outside 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 cells are closely related to certain functions of cells, such as carbohydrate metabolism, glycogen storage and protein metabolism, excitability and conductivity of nerves and muscles including myocardium, etc.
