Often when a person is admitted to the hospital, an intravenous solution of normal saline is begun, since this does not harm the patient, because normal saline is isotonic to your blood
Isotonic solutions are those that have the same amount of water and other solutes in them as the cytoplasm of a cell. Since there is no net gain or loss of water, placing cells in an isotonic solution will not cause them to either shrink or swell. Salt and water are combined to make saline.
Because of its salt content (0.9% saline), which is comparable to that of tears, blood, and other bodily fluids, a normal saline solution is known as normal. Isotonic solution is another name for it. The 0.9% strength sodium chloride (salt) solution in water is referred to as "normal saline." Because its osmolarity is so close to that of blood, only this concentration of sodium chloride solution is referred to as "normal" saline.
