saltvannsløsning

Saltvannsløsning, also known as saline solution, is a mixture of sodium chloride (table salt) and water. The concentration of salt in the solution can vary depending on its intended use. A common type is physiological saline, which has a salt concentration of approximately 0.9%. This concentration is isotonic with human body fluids, meaning it has a similar osmotic pressure.

Physiological saline is widely used in medicine. It is employed as an intravenous fluid to rehydrate patients, to administer medications, and as a cleansing solution for wounds and medical equipment. Its isotonic nature makes it well-tolerated by the body, minimizing cell damage. In laboratory settings, saline solutions are also used for various research purposes, including cell culture and sample preparation.

Beyond medical applications, saline solutions have other uses. For instance, a mild saline solution can be used for nasal irrigation to relieve congestion. In some DIY contexts, it might be used for cleaning or as a component in homemade remedies. The preparation of a saline solution involves dissolving the correct amount of salt in purified water. Safety precautions are important, especially when preparing solutions for medical use, to ensure sterility and the correct concentration.
