Saline solution 7% vs 9%: Anyone switched?

Posted by dee65 @dee65, Jun 8, 2022

My med and nebulizer supplier has recently told me they won’t be carrying 7% saline anymore because most doctors have switched to 9% now. Mine has not. Have any in the group been switched?

Interested in more discussions like this? Go to the MAC & Bronchiectasis Support Group.

At NJH, I was told that the standard salinities for airway clearance are 3%, 7%, and 10%. 5% is not a standard, so those who get it need to have it made at a compounding pharmacy. NJH say that 10% is typically hard to use by patients with COPD or asthma. 3% is the threshold for survivability of NTM, which is the salinity of sea water. This is why they say that swimming in sea/ocean water is safe versus swimming in a pool or body of freshwater.

Hi Everyone!
.9% is isotonic, the same as our body fluids. It is the lowest percentage to nebulize. The next is 3% and then 7% and they are hypertonic, saltier than our body fluids. There is the possibility that 3 and 7% have antimicrobial properties in addition to hydrating our airways. With .9% those anti-microbial properties wouldn’t be there, but the solution would still moisturize and help liquefy mucus. When I’ve had some rough patches with a sore throat, My doctor suggested switching to .9% or 3% for a period of time.

NTMir just released this video by Dr Kevin Winthrop, on the benefits of nebulizing Hypertonic saline for patients with NTM including MAC and other bacteria. https://www.youtube.com/watch?v=eNMGH8PTwRI

Thanks! That was a great video — I was interested in him saying that he recommended for his stable MAC patients to only nebulize once a day, but to then vigorously exercise in the afternoon as their second airway cleanse.
Aerobic exercise DOES open the airways and brings up sputum, so I am going to try that instead of nebbing twice a day and see if it works

@poodledoc Thanks for sharing that video with us. I do not use a device after nebulizing as it never seemed to help in the past but after viewing I will give it another shot. I am able to bring up sputum with just the hypertonic saline. I guess the more productive, the better. Also, he inspires to do more aerobic exercise. I liked his come from.....maybe because he is just one laid-back dude.
Best wishes for good health in the coming year.

I could have had Omicron COVID--no fever, but my sinuses went crazy and affected my lungs which are not usually productive. I was nebbing 4xday. I decided to up the percentage to 9%. (I have a %15 saline solution that I half with sterile water, usually get the 7.5%.) I found the 9% to be effective with no adverse reactions.

PS Although my rapid test for COVID was negative, I lost my sense of smell for ten days.

The title of this original post "Saline solution 7% vs 9%: Anyone switched?" has unfortunately created a lot of confusion. The 9% should actually read 0.9% which is normal saline. Is there a way to get that changed?

That is correct. 0.9% is the same as the body naturally has and what you might give to a child or baby. It does very little for me. 3% also did not work well enough for me. 7% does more to avoid exacerbations (for me). But they might make a 9% not to confuse things. I know they make a 12% which would be very strong.
