@glendamoseley This is how the inhaled saline can be beneficial. The saline is 7% sodium chloride. It is inhaled as a mist by using a nebulizer. The benefits are that it adds moisture to the phlegm making it thinner and easier to cough up. Phlegm is often very sticky and clings to the insides of your lungs and bronchial tube. Thick phlegm is attractive to mac and pseudomonas. They look for goo to colonize in. It also causes a mild irritation which sometimes will induce coughing. You want that. You want to cough up as much gunk as you can. Did your mom ever tell you to gargle with warm salt water for a sore throat? Well, it is kind of the same concept. You are putting a salt mist into the lungs. The salt kills bacteria or at leadt makes it inhospitable to bacteria. It is good lung hygiene to nebulize saline twice a day. I will pull the saline chart next for you to look at. Back in a minute.....
