@lorifilipek You make a good point and it did make me wonder a bit if the results could have been skewed to show PulmoSal killed the bacteria better to better sell their product. For me it's all about the acidity. In the early stages of my coughing history I was diagnosed with LPR (laryngopharyngeal reflux) or Upper Airway Reflux as the reflux can actually get down into your bronchi. Long story there but I got that under control with lifestyle changes. But I believe the damage to my airways from that reflux caused my bronchiectasis, I believe then I got NTM/MAC which made the BE even worse.
Reflux consists mainly of HCl (acid) and pepsin. It has been shown that pepsin is the really bad player in LPR as it is the enzyme that breaks down protein in your stomach. Pepsin has the ability to attach itself to tissue such as the delicate lining of your airways for a long time until it is activated by anything acidic in nature, at which point it starts to eat away at the lining of your airways causing damage. So I want to always make sure I am not inhaling anything acidic into my lungs. I used a pH strip to compare the acidity of PulmoSal (the pH was about 7) vs HyperSal (the pH was about 6). On the pH scale a 6 is 10X more acidic than 7.
