@franthony Hi. 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. Since you are not coughing, you may not need the saline at this point. You may want to discuss with your dr as to whether it would be a good prophilaxis (preventative measure).

Here is the saline (sodium chloride) chart Across the top is the % (strength) of the saline. Down the far left column is the list of the bacteriums that it kills. The chart shows that 7% saline will help to kill back mac, and mai. I presently test negative on everything, but doing the saline treatment helps keep it away. I hope this helps you to understand why we use it.
