A nebuliser is an apparatus used by cystic fibrosis sufferers. Cystic fibrosis is a congenital disease that causes mucous build-up in the lungs. A nebuliser fits into your mouth and delivers a fine mist of medicine to your lungs. You may need to dilute the medication with saline solution in some cases. A saline solution is salty water that is similar to the body's own fluid composition. If you choose to make your own saline solution, ensure all the instruments and ingredients you use are sterile.
