How to Use Saline in a Nebulizer

Using saline solution in a nebulizer is an excellent and safe way to help lung congestion. The saline solution helps break up mucus in the lungs so that it may be expelled by a cough. It can also soothe throats and airways that have become irritated from too much coughing. Since saline solution is just sterile salt water and not an actual medication, it is completely safe and free of side effects.

Assemble your nebulizer.

Detach the tubing from the nebulizer. Allow the compressor to run until all moisture inside the tube is gone, and then turn it off.

Disassemble the nebulizer and rinse all parts with warm, soapy water. Allow the parts to dry thoroughly on a clean paper towel before the next use.
